Job Description

About the position

We are seeking a Senior Cloud API Developer to maintain and develop our cloud APIs which allow users to interact with our photonic quantum hardware. In this role, you will maintain and expand a microservices ecosystem that orchestrates complex optimization jobs, manages user access, and connects high-level cloud APIs and low-level hardware controllers. You will be working in a hybrid environment, developing services that will run on cloud as well as on resource-constrained on-premise hardware stacks. This is a role that requires expertise in distributed systems, asynchronous event messaging, and strict API security standards.

Design, build, and maintain high-performance RESTful APIs using Golang and Python to support a broad ecosystem.
Architect asynchronous, event-driven workflows using RabbitMQ (or similar message brokers) to decouple job scheduling, hardware execution, and result processing.
Optimize service-to-service communication to ensure low latency and high reliability across a distributed stack.
Monitor system health and implement distributed tracing to debug complex microservice interactions.
Implement industry-standard security best practices for API authentication and authorization (OAuth2, OIDC, mTLS).
Work within existing deployment and testing patterns to add new services to CI/CD.

5+ years of professional backend software engineering experience.
Expert proficiency in Golang and Python for production services.
Strong background in message queuing systems (RabbitMQ, Kafka, or NATS) and event-driven architecture patterns.
Proven track record of implementing API security best practices, including OAuth2, JWT, and protection against OWASP Top 10 vulnerabilities (Injection, Broken Auth).
Experience designing scalable database schemas (SQL, NoSQL) and managing databases with indexing and TTL.
