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.
