CTO // Co-Founder // Early Stage Engineer (LLMs, Go and React)
We're looking for a high-caliber engineer to join as a Founding Engineer. You should be deeply hands-on with code, technically opinionated, and capable of building production systems from scratch. This is a role for someone who enjoys execution but also has the potential (or ambition) to lead technology at a company-defining level.
What You'll Do
- Build and own core infrastructure and backend systems
- Design and implement APIs, data models, and scalable services
- Collaborate closely with founders on product direction and technical architecture
- Ship code fast, validate assumptions, and iterate
- Lay the groundwork for the future engineering team (tooling, processes, and architecture)
Core Technical Requirements
- Proficient in one or more modern backend languages (e.g. Python, Go, TypeScript, Java, Rust)
- Strong systems design skills - you can model real-world systems and reason about scale, latency, and trade-offs
- Comfortable building from zero - greenfield work doesn't scare you; in fact, you prefer it
- Experienced with cloud infrastructure - AWS, GCP, or similar; IaC (Terraform, Pulumi, etc.) is a plus
- Competent with databases and data modeling - SQL and NoSQL, designing schema for scale
- Comfortable writing tests and deploying production systems - you care about code quality and reliability
Bonus Experience (Not Required, but Valuable)
- Worked at a Pre-Seed or Seed-stage startup through to Series A
- Built or deployed software used by enterprise customers
- Experience with applied machine learning or MLOps (not just academic or notebook-based work)
- Exposure to event-driven architectures, streaming systems (Kafka, etc.), or real-time data pipelines
- Frontend experience in React, TypeScript, or similar modern frameworks
What We Offer
- Early-stage equity and the opportunity to shape foundational decisions
- High ownership, zero bureaucracy - build what matters, fast
- Founders who value engineers, ship code, and work closely with you
- A role that grows with you - if you have CTO potential, you'll have a path
You should apply if:
You're a product-focused engineer - you solve problems through code, you like building things that work, and you've got the technical depth to back it up.
