Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Product Engineer (Frontend/UI) - **Company:** Pailot - **Location:** Barcelona, Spain - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), Continuous Integration, DevOps, Python (Programming Language), Data Streaming, TypeScript, Backend, Fastapi, AngularJS, Front End Software Development - **Published:** July 1, 2026 - **Apply:** https://www.jobleads.com/es/job/e7dbf8e40dd7acc698617b9435086dc21 ## About the Role This is a frontend-focused role for someone who combines strong engineering with product judgment. You should be comfortable building high-quality UI in Angular and TypeScript, but also thinking beyond implementation: What problem are we solving? Is this the right scope? Is there a simpler or more robust way to do it?, * Strong Angular and TypeScript skills, including component design, stateful UI, forms/workflows, and maintainable frontend structure * Ability to turn repeated workflow problems into reusable components and interaction patterns * Product judgment: you ask what user decision the UI needs to support before implementing the requested screen * Ability to spot when a workflow hides important state, requires too many clicks, or makes the planner remember information the UI should show * Comfort working from incomplete specs by asking the right questions, proposing cuts, and validating assumptions early * Clear communication with product and engineering, including the ability to challenge unclear scope without becoming adversarial * Pragmatic execution: you know when to ship a small clean improvement, when to refactor first, and when to cut scope Helpful * Experience connecting frontend features to backend services and APIs * Some familiarity with Python, FastAPI, or similar backend frameworks * Experience in B2B SaaS, operational software, or workflow-heavy products * Exposure to manufacturing, APS, ERP, MES, production planning, or similar domains * Familiarity with CI/CD, deployment, observability, or performance topics * German language skills ## Description * Build and improve complex frontend workflows in Angular and TypeScript * Translate rough product ideas and complex domain requirements into clear, maintainable interfaces * Improve usability in areas where workflows are confusing, overloaded, or unnecessarily complex * Take product problems from rough idea to production, ship iteratively, and improve the solution after release * Work closely with product on scope, trade-offs, and solution design * Actively shape backend functionality where it affects the product experience, especially around APIs, data flows, and feature integration; implementation support is helpful but not the core focus * Improve component structure and interaction consistency in workflows that have grown organically * Significantly improve product usability * Contribute to a product that is used in operationally critical manufacturing environments, * Not a generalist full-stack role with equal depth expected across frontend, backend, DevOps, and architecture Example problems you might work on * Improving a planning board used by production planners * Designing workflows for resolving machine capacity conflicts * Making schedule changes after disruptions easier to understand and act on * Simplifying interaction patterns in complex planning and execution scenarios * Turning rough product needs into shippable, usable frontend improvements ## Related Videos - [Intro to FastAPI](https://www.wearedevelopers.com/videos/462-intro-to-fastapi) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Building an agentic software factory: How we rebuilt product development at Pipedrive](https://www.wearedevelopers.com/videos/100261-building-an-agentic-software-factory-how-we-rebuilt-product-development-at-pipedrive) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Building and Deploying Multi-Agent Systems with ADK and Vertex AI](https://www.wearedevelopers.com/videos/1918-building-and-deploying-multi-agent-systems-with-adk-and-vertex-ai) ## Related Articles - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023) - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023)
