Senior Backend Engineer
Builds scalable backend services in Go for cyber and electromagnetic systems, handling real-time data with graph databases, event-driven architectures, and high-throughput APIs on AWS. Requires 5+ years experience, Go proficiency, and graph DB expertise.
About the job
Responsibilities
- Design and implement scalable backend services in Go that improve operator decision-making and response.
- Build high-performance APIs that power customer-facing workflows and internal platform capabilities.
- Model complex relationships in graph databases and optimize schemas and queries for speed and clarity.
- Implement event-driven systems (e.g., with NATS) to process real-time operational data streams.
- Develop and maintain automated tests to protect correctness, security, and performance as the system evolves.
- Build and operate microservices deployed on AWS, with an eye toward resilience and cost-aware scaling.
- Create and improve CI/CD pipelines that enable fast, secure delivery of new capabilities.
- Partner with cyber operations experts to translate domain needs into robust product features.
- Collaborate with frontend engineers on API contracts and data structures that are efficient and usable.
- Evaluate new technologies and patterns that could unlock better operational outcomes.
Requirements
Must Have:
- 5+ years of professional software development experience building backend (or full-stack) applications.
- Strong proficiency with Go (Golang) and have shipped production services with it.
- Experience working with graph databases (Neo4j, AWS Neptune, or similar), including schema design and query performance.
- Working knowledge of event-driven architectures and message queues/streaming systems.
- Experience building and maintaining APIs (REST and/or GraphQL).
- Experience with cloud infrastructure, ideally AWS, and understand cloud-native deployment patterns.
- Hands-on experience with containerization and microservices architectures.
- Strong foundation in secure coding practices and can reason about security tradeoffs.
- Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
Nice To Have:
- Delivered software in defense, security, or other mission-critical environments.
- Built systems for analysts, operators, or high-tempo users where speed and reliability matter.
- Integrated AI/ML capabilities into production systems (inference, pipelines, or tooling).
- Experience with large-scale data processing and analytics workloads.
- Contributed meaningfully to open-source projects.
- Used observability tooling (metrics, tracing, logging) to debug and improve production systems.
