Principal Software Engineer — Trade & Blockchain

What You’ll Do

• Write and own substantial amounts of production code in the most complex, high-risk, and business-critical areas of the platform. - Take end-to-end ownership of system behavior in production, especially under failure, stress, or adversarial conditions. - Operate confidently in ambiguous problem spaces, defining constraints, risks, and execution paths when clarity does not yet exist. - Anticipate and neutralize systemic technical, operational, and product risks through careful design, invariants, and operational discipline. - Simplify complex systems by eliminating accidental complexity, unsafe patterns, and brittle abstractions. - Set technical direction primarily through reference implementations, durable abstractions, and sustained ownership of core systems. - Act as one of the strongest technical coaches on the team through high-signal code reviews, design discussions, and example. - Influence product and technical decisions by deeply understanding system behavior, user incentives, and long-term trade-offs. - Participate actively in incident response, and ensure durable improvements through root-cause analysis and follow-through. - Raise the bar for correctness, reliability, and operability by making the right designs and behaviors the default for others. ## What We’re Looking For

We’re looking for exceptional individual contributors who consistently demonstrate strong performance across our core competencies, and who provide outsized leverage through a small number of exceptional strengths. In particular, you should have:

• A track record of owning and evolving complex, production-critical systems. - Exceptional engineering judgment in ambiguous, high-risk, or adversarial environments. - Deep comfort reasoning about failure modes, edge cases, and second- or third-order effects. - Strong operational ownership, including designing for observability, safe failure, and recoverability. - The ability to simplify complex systems without losing essential correctness or safety. - A demonstrated ability to influence others through code quality, design clarity, and technical credibility. - Clear, precise communication, especially when articulating risks, trade-offs, and system behavior.
