Fortivra · Stockholm (Hybrid) · Full-time

About the role

We're an early-stage, stealth-mode company working at the intersection of AI and enterprise security. We're building something new for a problem that large organizations spend enormous amounts of money on and still can't solve well. We can't say much more here - the interesting parts we'll share under NDA, on a call.

We have a working prototype, serious enterprise conversations underway, and a sharp, contrarian point of view about where this market is going. You'd join early, as a senior engineer with real ownership of major systems and a strong voice in the architecture - the kind of role where what you build is visible in the product, not buried in a backlog.

What you'll do

• Own features end-to-end - from data model and API through to the interface our customers rely on daily.
• Build core platform systems that turn large volumes of messy, real-world data into something structured, trustworthy, and useful.
• Design data and orchestration layers that have to be both fast and correct under real scrutiny.
• Drive technical decisions on the systems you own, and raise the bar for the engineers around you.
• Help set the engineering culture - how we test, ship, review, and move fast without breaking trust.

Our stack

You don't need every box ticked, but this is the world you'd work in:

• Frontend: React, Vite, TypeScript, Tailwind
• Backend: Python, FastAPI
• Data & orchestration: graph and streaming data systems, agentic AI orchestration
• Infra: Kubernetes, cloud-native deployment

What we're looking for

• 5+ years building and shipping production software across the full stack.
• Genuine range - comfortable owning a feature from database to pixels without needing a separate team for either end.
• Strong product instincts. You ask "should we build this?" before "how do we build this?"
• Comfort with ambiguity. At this stage the spec is often a conversation, not a ticket.
• Bias toward shipping, balanced with the judgment to know where correctness is non-negotiable.
• Clear written communication. Small team, high autonomy, low meeting overhead.

Nice to have

• Experience with LLM/agentic systems in production (not just demos).
• Background in a high-trust, regulated domain (security, fintech, infrastructure).
• Graph database experience.
• You've been early at a startup before and know what that actually costs and rewards.

Why join now

• Real technical ownership. You'll own major systems end-to-end and have a genuine say in the architecture - not a narrow slice handed down from above.
• A category in the making. A rare chance to help build something new rather than iterate on someone else's playbook.
• The frontier of AI and security. Hard, original problems with no answer waiting on Stack Overflow - the kind of work that makes you sharper.
• Proximity to what matters. Close access to the founders and to real enterprise customers shaping the product. High trust, low bureaucracy, fast decisions.
• Room to grow. As an early senior hire, you'll have a natural path to broader technical leadership as the team scales.

Logistics

• Location: Stockholm, hybrid. Strong remote candidates within EU time zones considered.
• Eligibility: Must have the right to work in Sweden/EU.
