- Strong debugging skills β youβre comfortable fixing production issues quickly and safely.
- Experience executing from technical design docs or ADRs and delivering reliable, high-quality code.
- Practical understanding of queues, background jobs, retries, idempotency, and distributed system basics.
- Solid database knowledge β Postgres schema design, migrations, and query optimization.
- Comfortable working asynchronously with teams across time zones.
- Bonus: OpenCV or computer vision exposure, or experience integrating LLM/AI microservices.
What Success Looks Like
- Youβve resolved production issues that previously took hours to debug.
- Youβve implemented a new backend service end-to-end following an ADR.
- Youβve refactored messy legacy code into clean, testable modules.
- Youβve added metrics that make performance bottlenecks visible and actionable.
- Youβve earned trust by delivering stable, maintainable code week after week.
Compensation & Setup
- Competitive global salary
- Equity options
- Performance and quarterly bonuses
- Home-office stipend & hardware budget
- Learning and professional development support
Remote-first. Preference for candidates within Β±4 hours of London (GMT).

You will be part of a mission-critical product that collects, transforms, and transmits data for dynamic visualization on tactical maps and for integration with external analytical systems. The speed and reliability of your code will directly impact how this data is used in real-world decision-making processes.
If you want to work on a product with purpose, where your code has real-world impact - weβd love to meet you.
What You Will Do
- Build and maintain backend services for ingesting, processing, and distributing real-time geospatial data
- Design RESTful and WebSocket-based APIs to serve both internal systems and third-party integrations
- Optimize data flow and system performance to minimize latency and maximize throughput
- Write clean, tested, and maintainable code using modern Python frameworks (Flask or FastAPI)
- Collaborate with front-end engineers, DevOps, and analysts to ensure consistent delivery of reliable data
- Contribute to architecture and system design discussions focused on performance and scalability
What You Need to Join Us
- Proficiency in building Python backend services β you write clean, efficient code and know how to ship reliable systems.
- Experience with Flask (or FastAPI), REST APIs, and Socket.IO (or WebSocket) communication.
- Basic knowledge of NumPy and Pandas
- Solid understanding of PostgreSQL and MongoDB databases.
- Experience with Python testing frameworks (e.g., pytest)
- Fundamental understanding of interaction between frontend and backend
- Understanding of programming patterns and their practical application
- Familiarity with handling sensitive data and basic principles of secure backend architecture.
- Ability to optimize database performance for speed and scalability.
Nice to Have
- Basic understanding of CI/CD pipelines and cloud deployment (e.g., AWS, FluxCD).
- Familiarity with analytical geometry or geospatial data: coordinates, shapes, movement modeling.
- Experience working with real-time systems or high-throughput applications.
Why Join Us
- Make Real-World Impact - Our tech is proven in national defence.
- Challenging Work - Youβll build what hasnβt been built by anyone before.
- Military deferment - For full-time employees.
