What this job asks for AI summary
An early full-stack engineering hire at a stealth-stage fintech/blockchain startup, responsible for building and owning features across a web application and API layer that handles real financial flows. The work spans TypeScript/Node.js backends, React/Next.js frontends, PostgreSQL, AWS infrastructure, and deep DeFi integrations — including smart contracts, oracles, and protocols such as Aave, Uniswap, and Pendle. Best suited to a senior engineer with strong DeFi hands-on experience who can operate with minimal oversight.

Why we read it this way (8)
No work location is specified in the posting; the role appears fully remote given the absence of any office or city requirement.
The title 'Full Stack Engineer' carries no seniority modifier, but the requirements describe a senior-level profile: 4+ years of experience, autonomous operation with minimal oversight, and end-to-end ownership — consistent with Senior.
DeFi/blockchain depth is framed as the primary requirement and is stated with firm language ('advanced', 'hands-on', 'able to design, integrate, and optimize'), so it is treated as a hard gate even though no single named protocol is individually mandatory. Centrifuge, Fireblocks, Pendle, Aave/Morpho, and Uniswap/Curve are listed as 'ideally' or contextual stack, so they are marked preferred.
Event-driven architecture (Kafka, Pub/Sub, or similar) is listed in the requirements block; Kafka is captured as the primary with Pub/Sub as an alternative.
Solidity and Rust are explicitly labeled 'Bonus' and are marked preferred accordingly.
Prior fintech experience (payment rails, ledger systems, compliance infrastructure) is labeled 'Bonus' and is a domain/context note rather than a named technology, so it is omitted from the skills list per extraction rules.
Compensation is stated as $140K–$200K base plus equity; equity terms are unspecified.
This posting reads as a fully-remote role, so it was scored against the national candidate pool rather than a single metro.
