Forward Deployed Engineer (FDE)

The Role

As a founding Forward Deployed Engineer (FDE), you will help shape how we solve problems for our partners, and set the patterns that will be inherited by the customer-facing hires that follow. Working alongside Ferenc and Craig, you'll be at a design partner's whiteboard as much as you're in our codebase. The role is just as much discovery and translation as it is development and deployment. Your work will be instrumental in figuring out how formal verification should fit into the rapidly evolving stack and workflow of the most sophisticated engineering teams on the planet.

Your work will include:

• Leading discovery by joining early customer meetings, owning technical scoping, and bringing research depth to prospective partner conversations
• Diagnosing which of a prospective partner's systems are fit for verification and proof of concept (POC) work
• Designing POCs and initial customer solutions with us, translating observations and requirements into tightly scoped deployments a small team can deliver rapidly
• Identifying capability gaps which recur across partners and feeding those signals directly into our research and development direction: what we train for, what we build
• Eliciting real specifications from complex systems and world-class engineering teams. Building trust while translating between prospective partners and the frontier where AI meets formal verification
• Staying hands-on between partner conversations. You are a key member of technical staff, building alongside the wider team

Requirements

We're looking for someone who has time spent inside or close to a high-accountability engineering culture in the mould of a Stripe, Cloudflare, AWS, Datadog, MongoDB or similar; you understand the value of correctness and verification. Domain expertise in formal methods or verification, either from research or from practical application. An understanding of specification-aware programming (Verus, Dafny, Viper), proof assistants and verification tools (TLA+, Lean, Roq, Isabelle). Experience building relationships with senior engineers and CTOs. Genuine interest in the commercial side of our work. Comfort with and excitement about the early-stage version of this work: consistently world class output, despite ambiguity, hands-on scrappiness, and rapid iteration.

• Active contribution to formal verification or program synthesis projects: Verus, Lean, Dafny, or similar
• Experience running production back-end services at scale; you've felt the pain of what testing can't prove
• Experience being accountable for distributed systems; you respect the failure modes that emerge from concurrency, consensus, and partial failure

Bonus Points

• If you actively contribute to formal verification or program synthesis projects: Verus, Lean, Dafny, or similar
• If you have run production back-end services at scale; you've felt the pain of what testing can't prove
• If you have been accountable for distributed systems; you respect the failure modes that emerge from concurrency, consensus, and partial failure

Benefits

• Compensation: Generous salary, with equity and additional benefits
• Location: San Francisco or London, with flexibility for customer and team travel - expect to be in-person frequently with Craig (SF, London) and Ferenc (Budapest, London)
• Visa sponsorship: available in both geographies for the perfect candidate
• World-class team and environment: an opportunity to build alongside deeply experienced founders, in a well-funded company that's backed by industry leading VCs and angels including Oriol Vinyals, Zoubin Ghahraman, Jonathan Frankle and Guy Podjarny, amongst many others
