Responsibilities
- Write high-quality, performant code primarily in Go.
- Implement new microservices while helping us responsibly manage and migrate away from legacy services.
- Work closely with product managers, designers, and data scientists to turn abstract requirements into concrete technical designs.
- Ensure our systems stay responsive under heavy load, optimising for both latency and reliability.
Requirements
- 3+ years of experience (5+ years for seniors) building and maintaining scalable backend services.
- We use Go. If you know it, great. If not, we’ll interview you in your strongest language (Python, C++, Java, Ruby, etc.). We hire for engineering fundamentals, not syntax.
- In-depth knowledge of relational and NoSQL databases (PostgreSQL, MongoDB, Redis) and experience with message brokers like RabbitMQ or Kafka.
- At least 1 year of hands-on experience with mapping-related work such as processing noisy geospatial data, map-matching techniques, or road network graphs and routing algorithms.
Nice to have
- Driver-side intuition for navigation systems (rerouting behavior, GPS drift, missed turns, real-world edge cases).
- Experience with routing engines like OSRM.
- Proficiency in C++.
- Familiarity with open geospatial datasets such as OpenStreetMap.
