AI Full Stack Engineer

SoSafe is Europe's leading human risk management company, trusted by 6,000+ organisations to turn their people into a line of defence against cyberattacks. We've built something real, and we're nowhere near done.

This role is on the Adaptive Defence team, SoSafe’s newest most innovative product where we build products fast, AI-native from day zero, and we put it in front of customers before it's perfect. We iterate in fast cycles. We're not here to maintain a roadmap. We're here to build what's next.

We've got the distribution, the customers, and the brand. What we need are builders: people who've taken something from 0 to 1, who prototype before they specify, who use AI to move faster, and who have no patience for process for its own sake.

Title and years don't decide this. What you've shipped does. If you're a builder, let's talk.

Location: Hybrid from Lisbon.

What you'll own

Ship, don't specify

• Own a product problem end to end: from framing to prototype to production.

• Move in short cycles. Days and weeks, not quarters. Your output is working software in users' hands, not decks.

• Own the feedback loop. Get in front of customers, learn, and ship the next version fast.

Build AI-native

• Agentic coding and rapid prototyping are your default, not a side experiment.

• You're a multiplier: you ship at a pace a conventional team can't match.

• You'll help shape how we build with AI. That's a happy side effect, not the mission. The product is.

• Our stack is TypeScript, React, Node, and AWS. We care more about how fast you ramp than what you know today.

Own the outcome

• You own the quality bar and the judgement behind what you build, not just the output.

• Make product, design, and scope calls without waiting for a committee, and own them when you're wrong.

• When the brief is incomplete, you narrow it yourself and move.

• Your name's on what ships. You're measured on impact, not tickets closed.

   

What we're looking for

• You've built 0 to 1. You've taken something from nothing to shipped, and you can point to the calls you owned and what came of them. Founder, indie builder, or early employee with outsized scope all count. Coordinating other people's work doesn't.

• You're hungry and not afraid. New domain, new stack, hard problem: you run at it. You'd rather ship something imperfect and learn than polish something that never ships.

• You build AI-native. AI tools are core to how you work, not an add-on. You have opinions on what's actually useful, and the scars to back them. Tool-agnostic on the way in; you'll converge with the team here.

• You keep your edge inside a structure. You've done things your own way. You know the difference between autonomy, which you'll have, and authority over everything, which nobody has.

   

Strong signals

• You've prototyped something real and put it in front of users in days.

• You've built your own tooling or workflow to go faster, and you can show it.

• You've got taste: a point of view on what great security or B2B SaaS looks like.

• You've lived startup or early-stage, where nothing works until you make it work.

• You actually care about human risk and cybersecurity, not just the market.

What you get

• The best tools, no rationing. Frontier LLMs are your daily driver, not a budget line you fight for.

• A lean, senior team with full ownership. No waiting on other teams, no design-by-committee, no politics.

• Build the product that sets the next standard in cybersecurity, with SoSafe's distribution behind you from day one.

• Room to move at your own speed. We won't slow you down with process.

   

What we offer

• Work/Life balance: Flexible hours, 33 vacation days

• Wellbeing and financial support: Access to Open Up, corporate discounts

• Connection & community: Virtual events, collaborative team activities, and opportunities for local meet-ups

• Tech equipment, referral bonuses, dog-friendly HQ
