Product Manager
Job Description
Halliday is a blockchain product lab building the unified cross-chain payments ecosystem for the next wave of onchain applications. Backed by a16z and Hashed, with a team from Stanford, Harvard, Compound, Meta, and Netflix, Halliday makes it easy for users to onramp, swap, and take onchain actions.

- Translate ambiguity into specs, prototypes, and artifacts that drive alignment across teams
- Run tight design-engineering-product cycles, shipping iteratively and fast
- Lead cross-functional execution across Engineering, Design, Partnerships, Legal, and GTM
- Own user research, competitive analysis, and feedback loops to inform product decisions
What we are looking for
- 4+ years of product management experience with a demonstrated track record of shipping user-facing products end-to-end
- UX instinct — can identify weak flows and work with design to fix them
- Spec discipline — can write PRDs that engineers actually want to build from
- Builder mentality: able to prototype, vibe-code, or wireframe to communicate ideas
- Startup fit: autonomous, high ownership, thrives without structure
