🧩 What you’ll own

As the team’s specialist on POS integrations, you’ll take full ownership of designing, building, scaling, and maintaining integrations with external POS providers and related services. This covers:

• Developing new integrations and extending current connectors
• Tackling integration incidents and root‑cause analysis
• Ensuring high reliability and performance as volume grows
• Architecting infrastructure for scalability, observability, and security
• Collaborating closely with product, backend, and DevOps peers

🎯 What we’re looking for

• Product mindset – you empathize with users (e.g., restaurants), prioritize impactful work, and communicate clearly across teams
• Backend focus – strong skills in server‑side development (TypeScript/Node, Python, Go, etc.) and database modeling
• Infrastructure expertise – experience deploying and maintaining services in cloud environments (GCP, AWS, Kubernetes, Docker, CI/CD, monitoring/logging)
• Integration know‑how – comfortable with REST / GraphQL APIs, webhook handling, message queues
• T‑shaped profile – deep backend + infrastructure skills, plus the ability to triage issues, propose solutions, and debug (inc. familiarity with observability)
• 2–5+ years building production services in SaaS or high‑volume systems
• Fluency in English and Spanish (we use both daily – Spanish for syncing, English for docs and code)

⚡ Extras we love

• Experience working with POS systems or in the restaurant/HORECA sector
• Familiar with domain‑driven design or microservices
• Background in incident response, SRE practices, or service-level objectives

🤝 Why you'll love it

• Ownership from day one – lead this mission-critical area as we expand
• Fast‑growing impact – integrations are core to scaling haddock into new markets
• Cross‑functional influence – work with product, customer success, and engineering to shape flow and experience
• Career growth – shape team practices, mentorship opportunities, and future technical strategy
• Great package – €35–50 k gross/year, hybrid remote, Urban Sports Club, snacks, central office near La Pedrera
