API Engineer

We’re looking for an exceptional API Platform Engineer who enjoys solving hard integration problems and building reliable data systems in secure cloud environments.

You will design and build high-performance APIs and data ingestion pipelines that power mission-critical applications supporting national security operations. These systems must operate reliably at scale, integrate with numerous external data sources, and run within AWS GovCloud environments.

This role is ideal for engineers who:

• Enjoy designing clean, well-structured APIs
• Think deeply about data flows, reliability, and performance
• Take pride in building elegant solutions to complex problems
• Like working with modern cloud infrastructure and distributed systems

You’ll work alongside business analysts, engineers, data specialists, and mission stakeholders (including 3rd party counterparts) to build systems that enable secure, real-time access to critical data.

WHAT MAKES SOMEONE GREAT IN THIS ROLE

• Top engineers in this role tend to:
• Take ownership of systems they build and continuously improve them
• Enjoy diagnosing complex problems across systems and data flows
• Think like system designers, not just coders
• Thrive in environments where engineering judgment matters
• Care deeply about clean architecture and elegant solutions

WHY ENGINEERS LIKE WORKING HERE

• Work on mission systems that support national security
• Solve real engineering problems, not just tickets
• Build systems using modern cloud architectures
• Collaborate with experienced engineers who value thoughtful design
• Opportunity to influence system architecture and engineering direction

What Your Day Might Include…

• Designing and implementing well-architected REST APIs that power mission applications.
• Building resilient data ingestion pipelines that move data across distributed systems.
• Developing cloud-native integrations using AWS services such as S3, Lambda, API Gateway, and event-driven architectures.
• Designing and optimizing PostgreSQL schemas and queries for high-performance workloads.
• Solving complex data integration challenges across multiple systems and formats.
• Building reliable ingestion pipelines capable of processing large volumes of operational data.
• Improving system reliability, observability, and performance across APIs and ingestion services.
• Collaborating with engineers and architects to evolve system architecture and platform capabilities.
• Troubleshooting production issues and continuously improving system stability and efficiency.
• Writing clear, maintainable code and well-documented APIs used across the platform.
• Helping drive engineering best practices across the team.
