Role Overview
We’re looking for a Software Development Engineer IV (Full Stack) with strengths in backend systems and frontend architecture. You’ll help shape how we build our writing and editing tool, ensuring it is modular, scalable, extensible, and maintainable as we continue adding features.

On the backend, you’ll design APIs and services that integrate seamlessly into the editor while supporting millions of users. On the frontend, you’ll bring structure and clarity — building modular, performant systems that make the editor easy to extend and maintain. You’ll thrive in environments with ambiguity, where not everything is fully defined yet, and where strong product thinking and design sense help shape the right solution.

Responsibilities

• Architect and implement modular backend systems and APIs that power the writing and editing experience.
• Shape the frontend architecture, ensuring it is modular, scalable, and capable of supporting complex editing workflows.
• Build user-facing features (React, TypeScript, CSS) with a strong emphasis on UX and performance.
• Ensure excellent developer experience (DX) by writing clean, self-documented, and reusable code.
• Balance backend flexibility with maintainability, designing systems that empower frontend teams to move quickly.
• Collaborate closely with product managers, designers, and engineers to shape both technical architecture and product experience.
• Prototype quickly, iterate often, and bring clarity to evolving product ideas.
• Mentor teammates and raise the bar on technical and architectural decision-making.

Qualifications

• 7+ years of professional full-stack production experience.
• Proven experience designing scalable APIs and modular backend systems.
• Strong frontend expertise (React, TypeScript, design systems, performance optimization).
• Experience structuring complex frontend applications (e.g., editors, dashboards, or large-scale products).
• Strong practices in testing, documentation, and code quality.
• Excellent communication and collaboration skills in cross-functional teams.

Bonus Points

• An eye for design and UX — translating product ideas and mocks into polished user experiences.
• Experience with design systems and component-driven development.
• Comfort working in ambiguous, evolving product spaces where iteration is the norm.
• Strong sense of product ownership and ability to think from the user’s perspective.
• Previous experience in SaaS, AI-powered products, or large-scale platforms.

Benefits & Perks

• Competitive salary & annual bonus
• Pension plan through the Zwitserleven Pension Fund
• A minimum of 33 days paid time off (including 7 public holidays and a day off on your birthday)
• A yearly personal development budget of €500
• Free consultations at OpenUp
• Discount and extra credits on a ClassPass monthly subscription
• A remote-friendly culture, including working abroad for up to 3 months
• The flexibility to work from home, including a monthly working from home allowance of €60 per month
• Parenthood: minimum of 6 weeks fully paid partner leave & 16 weeks fully paid maternity leave
• Travel allowance: (NS business card or kilometre allowance of €0.23/km)
• Healthy lunch and snacks at the office
• Employee referral program
• Premium access to QuillBot & LanguageTooler
