Forward Deployed Engineer

About Cala

AI is about to do a real share of the world's work. Whether we can trust it comes down to one thing: what it knows.

Cala is building the knowledge layer for that future. We're turning everything publicly known about the world (every company, person, filing and regulation, and every connection between them) into a single graph of verified facts that any agent can query. What Bloomberg and LexisNexis became for human professionals, Cala is becoming for AI: built with agents, for agents, at a scale no team of people could ever reach.

We raised a €7M pre-seed led by Lightspeed, launched in June, and global enterprises already run on Cala in production. We're based in Barcelona and San Francisco, and still small enough that everyone who joins now helps define what Cala becomes.

About the Position

We're looking for a Forward Deployed Engineer who enjoys building and also enjoys working with customers.

You'll be the technical person next to our enterprise customers and the developers building agents on Cala. You'll help them integrate our API and MCP server into their systems, build prototypes and demos with them, and solve the problems they find on the way. What you learn from them goes back to our product and engineering teams, and helps decide what we build next.

This is a high-impact role for someone who likes to understand a customer problem, write the code to solve it, and see the result in production.

Responsibilities

• Work directly with enterprise customers to understand their use cases and data workflows
• Help customers integrate Cala's solution into their products and AI agents
• Build production-ready solutions for enterprise customers, focused on workflows with real impact on their business (agents, RAG pipelines, tool integrations)
• Debug integration problems and find solutions together with the customer
• Turn customer feedback into clear requirements for the Product and Engineering teams
• Create documentation, examples, and guides that help other developers use Cala
• Contribute to a culture of clean, pragmatic, high-quality engineering

Requirements

Strong background in:

• Software Engineering, ideally with experience in customer-facing technical roles (solutions engineering, technical consulting, developer relations or similar)

Technical stack we commonly work with:

• Python
• APIs and integrations (REST, authentication, SDKs)
• LLMs and agent frameworks (function calling, MCP, retrieval / RAG)
• SQL and working with structured data
• AWS

Profile:

• 3+ years of hands-on software engineering experience
• Good communicator: you can explain technical things to engineers and to non-technical people
• You like to understand the problem first, and then build a pragmatic solution
• Curious about the AI ecosystem and modern developer tooling
• Comfortable in a fast-moving startup environment
• C1+ level in English (our customers work in English)

Nice to Have

• Knowledge graphs, financial data, or pharma data are a nice to have
• Builders at heart: hackathons, side projects, open-source contributions, active GitHub are all highly appreciated

We Offer

• Work alongside founders with a proven track record in AI and startups
• Build foundational AI systems with an "AI for good" focus
• High ownership, high autonomy, real technical challenges
• Join at an early stage and help shape both technology and culture
• A supportive, inclusive, and horizontal team environment

Locations

• Barcelona, Spain (On-site)
• San Francisco, United States (On-site)
