Software Engineer (Backend)

About the role

What you'll do

• Design, build, and maintain backend services in Go and Python across a microservices architecture deployed on Kubernetes
• Own features end-to-end - from technical design through deployment and iteration
• Work closely with clients and client-facing teams to understand requirements and translate them into reliable, scalable solutions
• Write clean, well-tested, production-ready code and contribute to code reviews
• Contribute to architectural decisions and help raise the technical bar across the team
• Help maintain and improve existing client implementations alongside building new capabilities

What we're looking for

• 3-7+ years of software engineering experience with a strong backend focus
• Production experience with Go and Python - we primarily use Go, but if your Go experience is limited you can ramp up
• Strong understanding of microservices and distributed systems
• Experience with Kafka or similar message queue systems
• Familiarity with Redis (or equivalent in-memory data stores) and MongoDB
• Experience working with Kubernetes and containerised services in production
• Comfortable with AWS and GitHub Actions CI/CD pipelines
• Comfortable working in a fast-moving, ambiguous environment with high ownership
• Strong communication skills - you'll be working closely with clients and cross-functional teams
• Genuine curiosity about AI and how it's reshaping how products are built

Nice to have

• Hands-on experience with AI/ML systems, LLM integration, or agentic workflows
• Exposure to vector databases or retrieval-augmented generation (RAG)
• Experience in an early-stage or scaling startup
• Background in security architecture or SRE practices

Location

Fully remote. We have offices in Madrid, Barcelona, and Valencia - visiting is entirely optional.
