About the Role

Were looking for aPrincipal Product Engineer who pairs deep engineering craft with strong product instincts. Youll work across the stack - mobile web backend - wherever the highest-leverage problem happens to live that quarter. You dont wait for a perfectly scoped ticket; you partner with product design and data to figure out whats worth building then ship it end-to-end.

We expect breadth. We also expect real depth in the mobile app ecosystem - our customer-facing experiences live there. But were not hiring a mobile only specialist. Were hiring a generalist with mobile chops who can lead an iOS architecture review on Tuesday and untangle a backend latency regression on Wednesday.

This role is open to candidates based within a commutable distance (generally up to 1.5 hours) of Lisbon however we also offer flexible hybrid working.

What you will do

• Identify scope and ship the changes that move business metrics - across mobile web services and data layers
• Architect long-lasting systems that hold up under real production conditions: performance reliability scalability offline behavior consistency
• Lead technical design reviews across teams weighing trade-offs not just in code but in product impact time-to-ship and operational cost
• Drive operational maturity wherever its weakest - release management observability incident response performance monitoring - including in the mobile apps
• Partner with PMs designers and engineering leaders to shape what we build why and in what order; youre a peer in those conversations not a downstream implementer
• Set the technical bar for the org by example: write the prototype prove the pattern then teach it
• Communicate trade-offs clearly to engineers product partners and senior stakeholders

What were looking for

• 10 years of software experience with significant time still spent hands-on in code - track record of shipping product-impacting work end-to-end not just owning a layer
• Real depth in the mobile app ecosystem (iOS and/or Android with strong fluency in Swift and/or Kotlin and the surrounding ecosystem - offline sync push auth persistence networking REST/GraphQL) - and credible breadth beyond it
• Demonstrated breadth: youve worked seriously in at least one of web frontend backend services data/infra platform tooling alongside mobile and can hold your own in code review there
• Strong product judgment: youve made calls about what not to build and can defend them with evidence
• Comfort troubleshooting in production across stacks - crash analysis latency tracing release-health debugging
• Excellent cross-functional collaboration; you make the people around you better.

Nice To Have

• Background in marketplaces bookings or other transactional consumer products
• Time spent close to data - experimentation analytics instrumentation or ML-adjacent work
