Your mission as a Staff Product Engineer With Invopop, users build workflows by chaining Actions, each of which is managed by an App. An App is a standalone service focused on a single goal, such as reporting an invoice to a tax authority, synchronizing it with an external system, or transforming/enriching a document. As a Staff Product Engineer, you'll be the owner of several Apps end-to-end, from the initial research to maintaining them in production. ~ Investigate new countries and systems: read regulations and technical docs, turn ambiguity into clear requirements, and consult local experts when needed. ~ Design and build integrations in Go on top of our modular architecture (NATS, CQRS patterns, Kubernetes on GCP). ~ Drive product decisions: define what "good" looks like, choose trade‐offs, cut scope when needed, and ship. ~ Support customers using your Apps and iterate based on real feedback. ~ Raise the bar across the team: review PRs, mentor engineers, and influence product and technical direction (architecture, patterns, quality). ~10+ years building backend systems (APIs, distributed systems, or complex domains).

Golang is a plus, but not required. ~ Fluent English: it's our internal working language.



~ Strong product judgment: you can scope, prioritize features, and make trade‐offs under ambiguity. ~ Customer empathy: you're comfortable speaking with customers and translating feedback into product decisions. ~ A track record of high‐agency: you've led projects end‐to‐end, improved systems over time, and made teams faster through reviews, standards, and mentorship.

Compensation €90k–€140k base + Stock Options, depending on seniority level. Where you'll work We're based in Madrid (Calle Guadalquivir, El Viso), 5 minutes from Nuevos Ministerios. You are expected to be in the office 3–4 days per month; travel expenses are covered.

Real ownership: you research, decide, build, ship, and support your own Apps. Work closely with Sam Lown (founding CTO of Cabify) and a small, high‐bar team. Hyper‐growth: 15 launches planned in 2026 and a 3× growth goal.

Full room to experiment: frameworks, databases, schemas, AI tools — nothing is sacred, as long as you can justify the choice.

No politics: product, taste, and good ideas win.
