Founding Engineer for Hire

The first technical hire at a startup makes or breaks the product. We step in as your founding engineer — understanding your business, talking to your users, making the architecture decisions, and building your product. Without requiring equity or a full-time commitment.

Let's talk about your product →

What is a Founding Engineer?

A founding engineer isn't just a developer. They're the person who translates a founder's vision into a working product — making critical decisions about architecture, technology, and what to build first.

Understands the problem

A founding engineer sits with you, learns your business, talks to your users. They don't wait for a spec — they help figure out what needs to be built and why.

Makes architecture decisions

They choose the tech stack, design the data model, set up the infrastructure. These early decisions determine whether the product can scale or needs to be rewritten.

Ships production code

Not just strategy. A founding engineer writes the code, deploys it, monitors it, fixes it at 2 AM. They own the product technically from end to end.

How we work as your founding engineer

We don't just execute tasks from a backlog. We embed in your business and operate like a cofounder.

1

We learn your business

We start by understanding your market, your users, and the problem you're solving. We talk to your customers if needed. This is how we make the right product decisions — not by guessing, but by knowing.

2

We shape the product together

What should we build first? What can we skip? What's the simplest architecture that solves the real problem? We make these decisions with you, not for you.

3

We build with AI-amplified speed

We use AI coding tools daily to ship at a pace that feels unreasonable. Senior engineering judgment combined with AI tooling means a two-person team delivers like ten.

4

We iterate based on reality

Ship, learn, adjust. We stay close to your users and your metrics. The product evolves based on what actually works — not what a roadmap said six weeks ago.

Why a founding engineer instead of...

...hiring a CTO?

A CTO costs equity you don't want to give yet, a salary you may not be able to afford, and months of recruitment. A founding engineer gives you the same technical leadership on flexible terms — start in 5 days, pause when you need to.

...hiring an agency?

Agencies deliver code, not product insight. They execute specs — they don't challenge your assumptions, talk to your users, or care about the outcome beyond the contract. A founding engineer is invested in your product's success.

...hiring freelancers?

Freelancers are great for defined tasks. But they don't make architecture decisions, they don't shape the product, and they don't bring strategic thinking. You still need someone to decide what they should build.

What you get

Product thinking

We don't just ask "how should we build this?" — we ask "should we build this at all?" and "what's the fastest way to validate this with real users?"

Architecture decisions

Stack selection, data modeling, infrastructure, deployment strategy. The decisions that determine whether you're building on rock or sand.

Production-grade code

Not prototypes — real, tested, maintainable code. Elixir, Phoenix, React, Next.js, Rails. Whatever the problem demands.

AI-amplified velocity

We processed 2.5 billion tokens building our last product. AI isn't a buzzword for us — it's how we ship 483K lines of code in 2.5 months with two people.

Our track record

We're Piotr and Kasia. Between us, over 20 years of experience building products — from early-stage startups to systems serving millions.

We wrote about how the developer role is shifting toward exactly this — founding engineers who understand the problem, shape the product, and use AI to build at extraordinary speed.
