Fullstack Developer — Startup

Salary: CHF 65'000 - 75'000 per year

Requirements:

• 1. Solid Laravel experience in production – you have shipped and
• maintained real applications, not just side projects.
• 1. React with TypeScript at a working level. You are comfortable on
• both ends, or ready to get there quickly.
• 1. You have worked with LLM APIs and understand how to build
• something reliable on top of them.
• 1. You take ownership. You will be our only developer – the CEO leads
• you on priorities and product, but the code is yours.
• 1. You write tests and you care whether things actually work.

Responsibilities:

• The company
• Intrinsa is a Swiss behavioural performance system. We show companies
• whether training and strategy actually change behaviour at work – or
• whether they only produced training hours on a report. Three products:
• a learning platform, an AI Companion, and an assessment module.
• Live with pilot customers in the DACH region.
• The team
• There are two of us. You become our developer – not one of several,
• the one. Direct line to the CEO, no layer in between.
• The CEO leads you on priorities, product and business context. On the
• technical side you take over from our current developer. The system is
• thoroughly documented, and he hands it over to you personally.
• Why Laravel and React
• We chose a mature, well-established stack on purpose. Laravel gives us
• development speed and brings most of what we need out of the box, the
• hosting stays affordable, and the community is large enough that
• answers are never far away. It was the right call for shipping fast –
• and it is a stack you can grow with.
• What you will do
• Take over the technical side: the products, the operations,
• eventually the roadmap.
• Develop the products further, with a focus on the AI Companion.
• Make it easy to set up new customers.
• Keep the quality high. The test suite exists and stays.
• Send us:
• CV
• References and certificates, if you have them
• One example of your work: repo, live project, screenshot, anything
• A few sentences on how you would approach scaling a product like this
• No cover letter. Show us what you have built instead. I'm more interested who you are in person than what I read on paper.
• We reply within a week. If you would rather talk directly, call me:
• +41 79 933 66 22. I learn more in ten minutes on the phone than in
• ten pages of application.

More:

Intrinsa was founded on a simple observation: companies invest heavily in training and strategy, and almost none of them can tell whether anything changed afterwards. Attendance gets measured. Behaviour does not.

We build the system that closes that gap. Our products combine a learning platform, an AI Companion that supports people in their daily work, and behavioural measurement – grounded in behavioural science, not in dashboards for their own sake.

We are a small Swiss company working with enterprise customers across the DACH region. Small team, real customers, decisions made in days rather than quarters.
