Senior Full-Stack Developer Slipcase

The Role

For the past 8 years, we have worked in partnership with a top-tier development agency to bring our vision to life and oversee the maintenance of our systems. We’re now looking for our first in-house developer to join our team; a confident, capable full-stack engineer ready to take ownership of a mature, production-ready platform and lead it into its next chapter.

You’ll be at the heart of the product, working alongside a dynamic and entrepreneurial team to design, build, and ship features that thousands of professionals rely on every day. You won’t be alone; we’ll continue working with our long-term agency partner on larger projects and Dev Ops support. But day-to-day, you’ll be the key technical voice in the room. This is a unique opportunity to shape the future of Slipcase tech from the inside out.

What You'll Be Working On

• Driving the evolution of our web platform and native apps
• Leading development on new product features, from concept to deployment
• Supporting API integrations, backend systems, and our internal machine-learning engine
• Working directly with the business team to translate needs into scalable code
• Balancing quick iteration with smart architecture and long-term maintainability

Our Tech Stack

• PHP (Symfony) + MySQL + Twig
• Native Android & iOS apps connected via a Type Script REST API
• Hosted on AWS with Docker containers + CDK orchestration
• A custom-built machine learning/NLP engine for smart content curation
• Integration with multiple third-party APIs for distribution and analytics

About You

You’re not just a developer —you're a problem solver, architect, and tech lead rolled into one.

• Experience writing clean, PSR-compliant, SOLID code
• Confident working independently, from scoping out features to pushing them live
• Experience with full-stack development (especially in our stack!)
• Keep performance, uptime, and data security top-of-mind
• Comfortable updating documentation, expanding test coverage, and helping with our ISO
  27001 compliance journey where needed.

Bonus Points if you:

• Have got AWS certifications or strong hands-on experience with AWS tools
• Are open to manage occasional out-of-hours deployments (with the freedom that comes with it!)

What We Offer

• The chance to own and evolve a mature, production-ready platform
• Real autonomy and input into the product roadmap and technology choices
• A flexible work setup (hybrid, or office-first - you decide)
• Be the first in-house dev and help shape the future tech team
• Work at a company where tech is at the heart of the business, not an afterthought
• Lead developer, but with the support and experience of a team of experts by your side.
