Description
Who we are
CryptoNext Security is a deeptech startup specializing in post-quantum cryptography. Our solutions help businesses and institutions prepare for a future where quantum computers will challenge traditional data security. We work with leading clients in finance, defense, and telecommunications.
On a daily basis, you will
• Build and maintain, in Go, the connectors that link CryptoNext Platform to our clients' tools (CLM, CMDB…): extracting, normalizing and exposing data through REST APIs.
• Consume heterogeneous third-party APIs: handle pagination, rate limits, retries, idempotency and provider outages.
• Design and evolve the API contracts exposed to CryptoNext Platform: OpenAPI and versioning.
• Model and query PostgreSQL, use Redis, and process work asynchronously through RabbitMQ.
• Containerize your deliverables (Dockerfile, Docker Compose) and get your changes through GitLab CI.
• Instrument your services (logs, metrics, traces), diagnose incidents in staging and production, and contribute to root cause analyses.
• Write the unit and integration tests that back your features, including against test doubles of provider APIs, and give QA what they need to automate the rest.
• Review code and help onboard new team members.
• Work directly with Product and QA.
• Use AI coding tools as leverage under your own judgement, staying accountable for what lands in the repo.
• Propose architecture changes and refactorings, and explain the trade-offs you accepted.
How we work
A team of six engineers, within our 15-person R&D department. Connectors live in a monorepo and follow a hexagonal architecture. Three days a week in our Paris office, the rest remote. Short feedback loops, high standards. We ship a working version early rather than polishing in isolation, and keep solutions as simple as the problem allows.
