Founding Engineer (Blockchain/Backend)
Founding Engineer (Blockchain/Backend)
Full Time • Los Angeles, CA
About ParlayX
ParlayX is an execution platform for sports prediction markets built for betting syndicates. We aggregate liquidity across venues and provide a single interface to execute trades.
About The Role
ParlayX’s mission is to become the premier execution and brokerage platform for sports prediction markets and the central hub connecting the ecosystem. We are hiring a founding engineer to help build the institutional grade product our syndicate clients rely on.
This role focuses on the blockchain and backend infrastructure powering our execution engine, venue integrations, and cross chain trade routing. As we close our fundraise and expand the team, this hire will have real ownership over technical direction, not just implementation.
Although backend focused, you will also work across the client application and ramp into new stacks as needed. We value engineers who learn quickly, take initiative, and push back. We do not assume the product vision or architecture is fully figured out and want someone who will speak up when they see a better path.
What You’ll Own
- Routing & Execution Engine: filling large syndicate orders across venues at best price
- Venue Integrations: Polymarket CLOB, SX Bet RFQ, and new venues
- Chain & Wallet Abstraction: Cross-chain Execution
- Technical Direction: shape architecture decisions and help drive the roadmap
Who You Are
- Strong systems/backend engineer with experience in prediction markets, DEX aggregators, or onchain execution.
- High integrity, low ego, and eager to learn.
- Take initiative and fail forward, you're not afraid to move fast and break things.
- Wants real ownership, not a ticket queue
Compensation & Logistics
Base Salary: 100-150k
Equity: Meaningful Equity
Location: In-Person Los Angeles (Remote Start Okay)
