Senior Full Stack Engineer

With SIMPLE as a partner in their pocket, users feel cared for and empowered to embrace - and stick to - new healthy habits.

We’re looking for a senior, product-minded engineer to join our technical marketing team and build web products, growth tools, integrations, and automation.

You’ll own initiatives end to end-from gathering requirements and researching solutions to shaping the UX, defining an MVP, designing the architecture, and shipping to production. We value strong engineering judgment, proactive ownership, and effective use of AI coding agents over a specific stack.

What you'll do:

• Own initiatives: clarify requirements, research options, define MVP scope, and deliver working solutions;

• Build web applications, APIs, automation, and internal tools using Node.js, Python, or Go;

• Create clear user flows, prototype interfaces, and turn ideas into intuitive, well-designed products;

• Make architectural decisions and balance delivery speed, reliability, and maintainability;

• Configure and improve agent-powered development workflows, integrations, and automated checks;

• Collaborate with marketing, product, and design; own testing, deployment, releases, and improvements after launch.

What we're looking for:

• 5+ years of professional software development experience, with proven ownership of products or substantial features;

• Strong backend skills in Node.js / TypeScript, Python, or Go—depth in one and flexibility across others; all three are not required;

• Hands-on frontend experience with React, Vue, or similar frameworks;

• Practical UX expertise and UI design skills: user flows, prototyping, usability, and visual consistency;

• Strong system design skills: architecture, data modeling, APIs, integrations, reliability, and scalability;

• Deep understanding and hands-on experience with AI coding agents and agent infrastructure: context management, tool integrations, task orchestration, and validation of generated changes;

• Experience turning loosely defined problems into production-ready solutions—not just implementing predefined tickets;

• Solid knowledge of SQL, relational databases, Git, CI/CD, and cloud infrastructure;

• Proactive execution, clear communication, and English for documentation and teamwork.

Nice to Have:

• Experience with marketing technology, analytics, experimentation, or growth engineering.

Perks and Benefits:

• Open-minded teams, a welcoming and inclusive company culture, plus the opportunity to make a real difference with a game-changing health tech product.

• A competitive salary package based on your unique expertise, skillset, and impact on the product plus stock options.

• Remote and hybrid work opportunities.

• The equipment whatever you need to be happy and productive.

• A premium SIMPLE subscription.

• 21 days annual leave, plus bank holidays (those observed where you live).

• Flexible hours. We focus on your results, not how long you spend at your desk.

About our values:

• Think deeper: We understand that in order to grow we need to make all our decisions reality-based and change our opinion based on what we learn. We appreciate data coming in various forms – quantitative and qualitative, feedback from users and colleagues, and strong and weak signals.

• Focus on impact: Results and speed matter. When we are competing to become an A-player in the digital health market, we don’t have the luxury of deliberation. We need to make decisions and changes quickly and, swiftly learn from our mistakes.

• Take ownership: We seek to improve all facets of our company even in ways beyond our job description. We seek and take responsibility for our actions and their impact.

• Push the limits: We encourage our team to explore new ideas, challenge conventional thinking, and continuously improve work.
