Founding Engineer

Own the whole stack, you do it all: server-side, client-side UI, data, the memory engine at the core of the product, infra, security and DevOps. This is a full-stack-everything seat, not a specialized slice.

Build the product shoulder-to-shoulder with the founder/CPO: the founder owns product direction and stays hands-on on the product day to day, while you own the technical surface. You build it together.

Harden the platform to sellable-grade: performance, reliability, and the rough edges that stand between a working product and one you can sell with confidence.

Retire the technical single point of failure: today the whole stack rests on the founder. You take the technical surface off the founder's plate, freeing the founder to stay on as CPO, focused on product, not stepping away from it.

Build the self-serve path from connecting a tool to a working company memory, and grow the integrations library behind it.

Own the security surface: tenant isolation and the access boundaries that let a company and its people share one memory safely.

The entire technical surface: backend, frontend, data, the memory engine at the core of the product, infra, security and DevOps. End to end, all of it.

The self-serve path, from connecting a tool to a working company memory, end to end.

The integrations library and the framework new connectors plug into.

The security and tenant-isolation surface.

Engineering culture: you set it, as the first engineer.

You've shipped and operated real production systems, beyond prototypes.

Comfortable across the stack: data, backend, and enough frontend to be dangerous.

You think in terms of isolation, correctness, and what breaks at scale.

You want ownership and equity over a big title and a big team.

Deep technical interest in what we actually build: scaling infra and production, but also truly understanding the layers of the memory (how it stores what it knows and how it learns from use) and wanting your hands in all of it.

Advanced, hands-on with AI: you build AI-augmented every day and treat 10x–100x output as the baseline.

Genuinely excited by the idea of a digital memory for companies and the people in them, caring about the mission as much as the stack.

A real fit with how we work (see "How we work"), our values are how we choose teammates, not wall art.

Cash

up to €6,500/month gross (payroll), or up to ~€11,000/month via your own management company

Equity

1.5–3% (4-year vest, 1-year cliff), more equity, less cash; 1.5% takes the full listed wage

Structure

Your call on both the split and the engagement: at 1.5% equity you take the full listed cash, and you can dial equity up toward 3% for less cash. Belgian payroll up to €6,500/mo gross, or invoice up to ~€11,000/mo via your own management company, same cost to us (we'd otherwise carry employer charges on top of gross), and you optimize your own tax.

You are hire #1.

Work directly with the founder and the AI agents that run on the same shared memory.

Office-first and close-knit. We work hard, in the room together, in a living-room-style office. Live too far? We are open to remote within the EU or US, with a digital living-room office that keeps the team close.

We plan to move to San Francisco around when the pre-seed lands (or at the seed round). Belgium-based and remote-friendly across the EU and US until then.

A 49" Samsung G9: real estate matters when you run multi-terminal workloads side by side, we get it.

An M5 Max (highest-tier) 128GB laptop.

Into open-model infra? We're open to exploring building our own, think an in-house NVIDIA GPU rack that scales with cards, to self-host open LLMs. If that's your kind of fun, there's room to build it.

Top-tier AI coding and writing tools, and plenty of budget for AI and anything else you need to multiply your output.

Snacks and a JURA coffee machine at the office, après-5pm apéro (drinks & bites), nice team lunches, and the occasional team dinner and activity together. Our founder is a French-trained chef who loves to cook for the team and host proper gatherings.

A company iPhone and mobile plan, the number's on us.

Vacation: if your first question is "how many days?", this role probably isn't for you (said with a wink, but only half-joking). Belgian law gives you 20 days of paid leave on top of 10 public holidays, and we want you to take them: a week in summer and a week over Christmas as a baseline, adjusted to your own holidays, location and religion.

20% of the company goes to its staff over time, because we believe in sharing.
