Web3 Engineer.

A Bitcoin-aligned Layer-2 protocol foundation had closed its Series A and was scaling the engineering bench ahead of a mainnet upgrade. The brief sat at a rare intersection — protocol-grade engineering depth combined with genuine Bitcoin-native fluency. We ran it on an exclusive contingent basis and closed in seven weeks.

The brief

What this seat existed to do.

The foundation was at the point in its arc where the protocol roadmap was outpacing the bench. A small founding engineering team had carried the work through testnet, and the next eighteen months required senior contributors who could own substantial surface area independently. The hire needed to operate at protocol level — consensus, bridge security, execution semantics — rather than as an applications engineer working against an existing chain.

The non-negotiable was Bitcoin-native fluency. Many strong protocol engineers exist in the EVM world; far fewer have spent meaningful time inside Bitcoin's scripting model, security assumptions, and Layer-2 design space. The foundation was prepared to be patient on geography and flexible on title in exchange for that intersection. Comp was set at the upper end of the Series A band, with a meaningful token allocation tied to a multi-year vesting schedule.

Market read

How we read the available pool.

The senior Web3 engineering market has fragmented along ecosystem lines. EVM-native engineers move readily between Ethereum, the major Layer-2s, and EVM-compatible chains; their toolchains, mental models, and shipping patterns translate. Bitcoin-aligned engineering sits in a much smaller pool — drawn from the historical Bitcoin Core orbit, from earlier sidechain projects, and from the small group of newer Layer-2s built directly on Bitcoin's security model. Most of that talent is already engaged on something, and most of it does not appear in standard search channels.

Our read going in was that the movable bench sat in two places: engineers a year or two into a Bitcoin Layer-2 who had shipped consensus or bridge code but were watching their roadmap stall, and engineers in adjacent ecosystems who had quietly maintained Bitcoin work on the side and were looking for a reason to consolidate. The lag in the market was that the foundations themselves were under-marketed — strong engineers did not know who was hiring, or what the next eighteen months actually looked like inside the more credible projects.

Shortlist

How we composed it.

We worked the brief across both pools and presented a shortlist weighted toward engineers with shipped Bitcoin-adjacent protocol code. The composition leaned senior — every candidate had owned a meaningful piece of consensus, bridge, or execution work in production — and was deliberately narrow on ecosystem fit.

  • Engineer from a tier-one Bitcoin Layer-2 who had shipped consensus changes to production and was looking for a smaller, more ambitious team.
  • Long-time Bitcoin Core contributor who had moved into Layer-2 work via a research foundation and wanted a more product-shaped environment.
  • Protocol engineer from an EVM-native Layer-2 with a multi-year history of Bitcoin-side contributions on personal projects.
  • Engineer from an earlier sidechain project whose roadmap had stalled and who was actively looking for the next credible Bitcoin-aligned bet.
Outcome

What was placed.

The hire came from the first archetype — an engineer at a more established Bitcoin Layer-2 who had shipped consensus-level changes and was ready to operate with more ownership and a shorter feedback loop than their current employer offered. The match on Bitcoin-native fluency was unambiguous; the question that took longest to settle was whether they would take on the broader scope the foundation needed.

The close landed in week seven, after a final conversation with the founding engineering lead that reframed the role as protocol ownership rather than a senior-IC slot. The candidate accepted within forty-eight hours of that conversation. The trigger was scope clarity, not comp — the offer terms had been agreed two weeks earlier and were not the point of negotiation at the close.

The firm's reflection

“The instinct on this brief was to widen the search by relaxing the Bitcoin-native requirement, and we held the line. The intersection of protocol depth and Bitcoin fluency is rare but not absent, and softening it would have produced a longer shortlist with weaker matches and a longer ramp. The lesson reinforced what we already believed about senior protocol searches: the foundation knew exactly which intersection they needed, and our job was to find it rather than to negotiate it away.”
