Job description

The Best of Both Worlds

About The Company

At Maisa, we believe great work happens when people have the freedom to choose the setup that works best for them.

Prefer the flexibility of remote work?

You’re welcome to work remotely. Most of our roles are currently focused on Spain, although depending on the position and profile, we may be open to hiring from other locations.

Looking for some social energy?

Our hybrid setup gives you the option to connect and work alongside teammates at our hubs in Valencia, Barcelona, Madrid and Murcia. And as we grow, our spaces will grow with us: when we build a team of more than 10 people in a location, our ambition is to create a hub there too.

We also want the time we spend together in person to be worth it. Today, that includes weekly transportation from the city center to our Valencia headquarters and weekly team lunches in Valencia and Barcelona, with more experiences to come as our teams and hubs evolve.

The Culture is OURS to Create

We’re still shaping how we work together—and that’s part of what makes joining Maisa now specifically exciting.

Everyone who joins has the opportunity to influence how we collaborate, connect, and build our culture. Rather than inheriting a finished playbook, you’ll have a voice in creating it.

Remote when you want flexibility. Together when you want connection. And a culture you can help shape from day one.

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.
