Tech Lead / CTO at a European DeFi venture studio.

Tech Lead with CTO scope, reporting to the founder. You would lead the protocol engineering team and carry the external technical voice — protocol reviews, technical due diligence, integration conversations with investors, ecosystem partners and counterparties, the audiences that test whether you can defend the architecture under questioning.

About the firm

Anonymised by default.

A European DeFi venture studio. The firm builds and operates multiple consumer-facing protocols on a high-throughput chain. Engineering- and design-heavy, around 25 staff. The studio's flagship protocol is live in production; two further protocols are in pre-launch build. Backed by DeFi-native investors.

We name a client on the mandate page only where the firm has approved publication. Where not named, the description above is intended to be enough for a senior candidate to recognise whether their pattern fits the brief.

The brief

What this seat exists to do.

Tech Lead with CTO scope, reporting to the founder. The seat owns the studio's technical agenda across the protocol portfolio.

Direct line management of around eight senior engineers spread across protocol engineering, smart-contract security, and on-chain infrastructure. Hiring two further senior engineers in the first six months.

Sets the technical bar for protocol audits, on-chain risk parameters, and the studio's relationship with its external security partners. The seat is the named technical owner the studio's investors and ecosystem partners speak to.

Europe-based with quarterly off-sites in Lisbon. Light travel to ecosystem events expected; most work is remote-first and asynchronous.

What we are assessing for

  • Has shipped at least one DeFi protocol to mainnet at scale, with public history of holding the line on security through real incidents.
  • Comfort across protocol engineering, contract security, and on-chain infrastructure — the seat is not a layer-of-management role.
  • An IC instinct that does not get in the way of building a team. The studio is small; the Tech Lead will spend half their time in code and half running the bench.
  • Patterns: a senior protocol engineer ready for first head-of role; a CTO from a peer DeFi protocol open to a smaller stage; a security-engineering lead from a major DeFi protocol with broader architectural reach.
The firm's read

Spectrum's read on this search.

You would lead the protocol engineering team and carry the external technical voice — protocol reviews, technical due diligence, integration conversations with investors, ecosystem partners and counterparties, the audiences that test whether you can defend the architecture under questioning. Part of the work is still in code. A mishire here would cost the studio roughly a year of roadmap, and the founder is prepared for a multi-month process.

— Peter Wood, Partner & Chief Strategy Officer
