Description

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 experienced software development manager to lead the Engineering and R&D team within Leo Infrastructure and IP 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. You will grow and lead a multidisciplinary team of software engineers, applied scientists, and security engineers building a neuro-symbolic reasoning platform: large language model agents combined with a knowledge graph and real-time asset state store that ground every conclusion in verifiable fact, so every automated decision is auditable. The platform automates incident response, threat analysis, offensive security testing, and detection authoring, backed by a high-throughput streaming pipeline that takes a detection from concept to production in hours. This is a unique opportunity to build a security platform from early stage through global scale, at a consequence level few teams ever encounter.

Export Control Requirement

Due to applicable export control laws and regulations, candidates must be a U.S. citizen.

Key job responsibilities

You will own the full software development lifecycle for the platform: architecture and design reviews, roadmap planning with science and security peers, code review, operational excellence, on-call and live-site response, and the hiring plan that grows the team. You are a player/coach: you set technical direction, own delivery across every workstream, recruit and develop the team, and stay in the code and the data enough to lead designs, unblock investigations, and review the hardest changes yourself. You will set the bar on model alignment, evaluation, and the interaction patterns that make automated decisions trustworthy at scale, and you will identify where automation can replace manual security operations while maintaining rigorous controls.

A day in the life

You will review agent and detection designs before they reach production, ensuring new capabilities enforce guardrails, produce auditable decisions, and degrade safely when models are wrong. You will evaluate incoming threat intelligence with your team and let it reshape priorities: when new reporting shows an adversary capability that maps to a coverage gap, the roadmap moves. You will obsess over the two latencies that define the platform, the time from event to detection and the time from detection to containment action, and drive both down release over release. You will drive your engineers and scientists through sprint execution, make tradeoff decisions between research ambition and delivery velocity, and coordinate with the security operations teams the platform serves so it reflects the workflows it is automating. You will work closely with principal engineers and partner security teams on integration points including telemetry ingestion, detection deployment, and automated response. This is an R&D role with a production mandate: the platform runs continuously across a global site portfolio and executes actions with real operational consequences.

About the team

Leo Infrastructure and IP 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.

3+ years of engineering team management experience
7+ years of engineering experience
