Careers

Amazon Leo is a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband network connectivity to unserved and underserved communities around the world. We are looking for an Applied Scientist to be a founding scientist on the Engineering and R\&D team within Leo Space Security. The team defends the manufacturing lines, launch sites, and global ground infrastructure behind the constellation from the most sophisticated threat actors on the planet. These requirements create open scientific problems at the intersection of agentic AI, real-time stream processing, graph-based reasoning, and behavioral analytics. You will build the science behind a neurosymbolic reasoning platform and the models that detect the behavior of sophisticated threat actors. This is an R\&D role with a production mandate, where you define the problem rather than solve a pre-scoped one, and every model, detection, and agent workflow you build becomes the system Leo's security teams use to protect the constellation. #### Export Control Requirement Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Key job responsibilities - Design and implement scalable, production-grade neurosymbolic systems that integrate symbolic reasoning over graph-based knowledge representations with LLM agents to deliver reliable, verifiable security outcomes. - Design and run reinforcement learning and fine-tuning pipelines (GRPO, PPO, DPO) to optimize language models for security reasoning, triage, and detection-authoring tasks. - Build behavioral and statistical models that detect threat actor behavior, and design the evaluation frameworks that measure model performance against that behavior before trusting a model in production. - Design and build multi-agent systems that autonomously triage, enrich, and contain security events, including the constrained reasoning, safety guardrails, and validation mechanisms that make automated decisions trustworthy at scale. - Own the end-to-end science lifecycle, from research and experimentation through production deployment, defining the metrics that measure system performance and real-world security impact. - Advance the state of the art through publications at top-tier venues, patents, or open-source contributions, and shape the scientific agenda and research culture from day one. A day in the life You will move between research and production in the same week: framing an ambiguous security problem as a scientific question, prototyping an approach, and partnering with software engineers to ship it as a capability the platform runs continuously. Security engineers on your team translate threat intelligence into the adversary behaviors that matter; you build the models that detect those behaviors and evaluate model performance against them. You will obsess over the two latencies that define the platforms, the time from event to detection and the time from detection to containment action, and design agents and detections that drive both down. You will backtest candidate detections against retained telemetry, review evaluation results before a model or agent capability graduates to automated execution, and deliver scientific artifacts that ship. About the team Leo Space Security protects the people, facilities, hardware, and supply chain behind a global satellite constellation. The Engineering and R\&D team within this organization builds the platforms and tooling the security pillar teams operate on, moving security operations from manual triage to correlation-based detection, automated response, and agentic AI. The team is composed of applied scientists, software engineers, and security engineers working across physical and digital security domains. #### Inclusive Team Culture In Amazon Security, it's in our nature to learn and be curious. Ongoing DEI events and learning experiences inspire us to continue learning and to embrace our uniqueness. Addressing the toughest security challenges requires that we seek out and celebrate a diversity of ideas, perspectives, and voices. #### Training & Career Growth We're continuously raising our performance bar as we strive to become Earth's Best Employer. That's why you'll find endless knowledge-sharing, training, and other career-advancing resources here to help you develop into a better-rounded professional. #### Work/Life Balance We value work-life harmony. Achieving success at work should never come at the expense of sacrifices at home, which is why flexible work hours and arrangements are part of our culture. When we feel supported in the workplace and at home, there's nothing we can't achieve.

Amazon Leo is a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband network connectivity to unserved and underserved communities around the world. We are looking for an Applied Scientist to join the founding cohort of the Engineering and R\&D team within Leo Space Security. The team defends the manufacturing lines, launch sites, and global ground infrastructure behind the constellation from the most sophisticated threat actors on the planet. The data is unlike anything you have worked with: badge and door-access events, asset movement, network telemetry, and industrial control signals from factories, ground stations, and launch facilities, all of which must be modeled, baselined, and defended. You will build the statistical and behavioral models that separate threat actor behavior from the noise of a global operation, and the privacy-preserving data representations that let detection science scale without exposing sensitive data. This is an R\&D role with a production mandate: every model you build becomes part of the system Leo's security teams use to protect the constellation. #### Export Control Requirement Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Key job responsibilities - Build behavioral and statistical models that baseline normal activity across heterogeneous security telemetry, including specialized industrial-control and factory-floor data sources, so detections extend to new environments with low false-positive rates. - Design privacy-preserving representations of sensitive security data, and verify that models and detections tuned against them remain accurate against the real data — turning data-protection guarantees into measurable, provable properties rather than assertions. - Define the methodology and own the analysis for difficult, loosely defined problems: gather complex data across domains, select the right techniques from a range of data science methods, and justify your approach with evidence. - Develop the metrics and evaluation frameworks that measure model and detection performance against threat actor behavior before a model is trusted in production. - Contribute to the team's neurosymbolic reasoning platform, adapting state-of-the-art techniques from the literature and shipping components at production quality. - Document your work with the rigor of a peer-reviewed publication, and communicate results clearly to both scientific and security-operations audiences. A day in the life You will move between analysis and production in the same week: profiling a telemetry source the team has never modeled, establishing what normal looks like for it, and shipping the baseline as a component detections build on. Security engineers on your team translate threat intelligence into the adversary behaviors that matter; you build and tune the models that detect those behaviors and evaluate model performance against them. You might spend a morning chasing a false-positive pattern to its statistical root cause, and the afternoon verifying that an anonymized dataset still preserves the signal a detection depends on. You will work semi-autonomously with guidance from senior scientists, backtest candidate detections against retained telemetry, and deliver scientific artifacts that ship.

Applied Scientists on the AWS Vulnerability Management (AVM) Builder Enablement team use program analysis, machine learning and generative AI for managing vulnerabilities and securing the software supply chain across AWS. Our scope covers the third-party open-source packages, language ecosystems, operating systems and kernels that AWS services are built on. Our goal is to take builders out of the remediation loop. When a vulnerability is disclosed or a package is compromised, our systems work out whether it actually affects AWS, generate the fix, check that it's safe and ship it at AWS scale, with one click or no clicks at all. New vulnerabilities are disclosed every day in the software AWS depends on, and finding and fixing them by hand doesn't scale. We build systems that detect vulnerabilities and work out whether the vulnerable code can actually be reached and exploited in a given service. They rank issues by real risk rather than raw severity scores, then fix them automatically. That can mean upgrading dependencies across ecosystems like Java, Python, JavaScript, Go and Rust, fixing breaking API changes, backporting patches, or patching operating systems and kernels across the fleet. Just as important, we check that each fix is correct and safe, so it can merge with little or no human review. Beyond known vulnerabilities, we protect the integrity of the software supply chain itself. Modern software is assembled more than it is written, and every dependency is a potential way in for attackers. Securing it means knowing what's in our software, where it came from and whether it can be trusted. Our work here includes building and analyzing software bills of materials (SBOMs), verifying package provenance and build integrity, and detecting malicious or compromised packages before they reach production. Our methods range from static and dynamic program analysis to LLM-based agents for code repair and upgrades. This is a chance to shape a fast-growing area that directly affects the security of AWS and its customers. You'll apply your technical depth in a fast-moving environment, and your work will reach thousands of AWS builders and services. Key job responsibilities • Design and build scientific approaches to vulnerability management. This includes vulnerability detection, reachability and exploitability analysis, dependency resolution, and prioritizing risk across third-party packages, operating systems and kernels. • Build program analysis techniques (static analysis, dataflow and call-graph analysis, binary and source analysis) that tell us precisely whether a vulnerability affects a given service or host. • Apply generative AI and agentic coding methods to fix vulnerabilities automatically. Examples include upgrading dependencies, fixing breaking API changes, backporting patches and migrating code across language versions. • Develop ways to check that automated fixes are correct and safe, such as test generation, behavior-equivalence checking, build and runtime checks, and confidence scoring, so changes can merge with little or no human review. • Own the design, experiments and delivery of well-defined science problems from start to finish. Turn ambiguous problems into measurable experiments and deliver solutions with measurable impact, such as faster time to fix, higher fix success rates and fewer false positives. • Work with engineers to turn research prototypes into production systems that run reliably across AWS's codebases and fleet. • Work with security, OS and kernel, and builder-tools partner teams to understand their remediation challenges and data. Find opportunities where science can make a difference. • Stay current with research in software security, program analysis, and ML for code. Contribute to internal and external publications where appropriate. • Share your knowledge through design reviews, documentation and mentoring of junior scientists and engineers. About the team The AWS Vulnerability Management (AVM) Builder Enablement team protects AWS from security risks in the software it depends on. Our mission is to take builders out of the remediation loop. We find the issues that matter, fix them automatically and ship the fixes safely at AWS scale. Scientists and engineers on the team work side by side, turning research in program analysis and generative AI into production systems that reach thousands of AWS builders.
