About us
We're an independent European digital product studio with a strong track record of delivering market-defining strategies and products for enterprises and governments. With about 200 talented people across three countries, premium AI capabilities and a diverse portfolio of international clients, we define, design and ship high-quality digital products, strategies and software. From global cloud-based platforms and large-scale apps to medical devices, banking software and augmented reality experiences. In a nutshell: if it lives and breathes digital, it’s what we do best.
Become a part of our team
At In The Pocket, you join a multidisciplinary team of designers, engineers, strategists and data specialists who care about the work as much as the people they work with. We work in small, autonomous teams that stay close to our clients and their users, and we give everyone the space to take ownership, speak up and grow. You’ll learn from colleagues across our studios, ship products that reach thousands or even millions of people and help shape what digital can do for leading organisations in Europe.
What you’ll do
As a Senior React Front-End Engineer, you design, engineer, test, improve, and deploy web applications that meet both user needs and business requirements. You’ve built deep technical expertise in modern web development, and now you also shape how your team builds: you guide features through their full lifecycle, set the technical direction on projects, and help the engineers around you grow. You take ownership of complex work, and your team and clients trust you to deliver consistent quality on your own.
- Architect, build, and deploy scalable and reliable full-stack web applications, from front end to back end, and make sound technical decisions that hold up as the product grows.
- Apply design patterns, steer the team away from anti-patterns, and actively drive improvements to the codebase and engineering standards.
- Own quality through test-driven development: you define the testing strategy for your projects and coach others on what’s worth testing.
- Design meaningful abstractions and shape the architectural decisions behind them, explaining the “why” to your team and stakeholders.
- Set up and improve deployment pipelines, own complex end-to-end releases, and put monitoring and observability in place for what you build.
- Build secure by default: you anticipate how attackers exploit weak spots, apply secure coding practices, and raise the security awareness of your team.
- Contribute to and help evolve design systems to deliver consistent, high-quality UI.
- Translate business requirements into robust, performant, and secure technical solutions, and challenge them where a better approach exists.
- Use AI tools (e.g. Claude, Codex) in your development workflow to write code, support reviews and work more efficiently.
- Act as a trusted technical point of contact for client stakeholders, keeping everyone aligned on priorities, trade-offs, and risks.
- Give and receive feedback openly, mentor and coach colleagues, and support them when they hit a challenge or ask a question.
Who you are
- You love building intuitive interfaces with solid UX.
- You understand the advantages and trade-offs of server-side rendering beyond SEO, and know when to choose which rendering strategy.
- You have a keen eye for building accessible applications following the WCAG guidelines, and you champion accessibility within your team.
- You know the OWASP Top 10 inside out and use it to build and review secure applications.
- You know how to build a robust and maintainable application that survives the test of time through extensive automated testing.
- You enjoy exploring new technologies and frameworks through pet projects or research, and you can judge when they’re ready for production.
- You have an open mindset: critical eye for quality, curious, eager to learn and not afraid to ask questions.
- You are a sparring partner and mentor for other engineers.
- You naturally take the lead on technical topics and guide the team through complex decisions.
- Expert in modern front-end development: HTML, CSS and component-based frameworks such as React.
- Strong software architecture skills and a deep grasp of software engineering best practices: Git, unit testing, code quality, CI/CD, documentation, dependency/version management, and monitoring.
- Solid back-end fundamentals: you know the difference between SQL and NoSQL databases and understand how OAuth and JWT tokens can provide a secure authentication experience.
- You master common API practices and know how to use OpenAPI or GraphQL specifications to build a type-safe front-end application.
- Hands-on experience with Docker and with cloud platforms like AWS, GCP, or Azure.
- Able to debug complex issues effectively using logs, stack traces, and error messages, including in production.
- Comfortable with the agility and pace of a growing or young company.
- Collaborative, proactive, and fluent in English.
- Bachelor’s in Informatics or Master’s in Computer Science (or equivalent experience).
- You embrace AI in your day-to-day development, stay critical about where it improves the quality of your output, and help your team do the same.
