📋 Description

• This is a hands-on technical leadership role, not a pure management one. You own the core and infrastructure layer: the infrastructure, the ledger, and the settlement service — the parts of the system where being wrong damages trust irreversibly. • You also own the architecture of the whole platform, the integration discipline that keeps parallel workstreams from diverging, and the relationship with the client on scope and go/no-go decisions. • The money-grade foundations. A PostgreSQL double-entry ledger (serializable, multi-AZ, RPO 0) where balances are derived from postings rather than stored as mutable counters, with idempotency keys on every mutation and a reconciliation job that pages on any discrepancy. When real money arrives, it must be new posting types — not a new system. • Determinism and recoverability. A single sequencer per game, an append-only event log, and snapshot-plus-replay recovery that produces bit-identical state. This is also what makes the engine testable against the source simulations. • Fail-safe behaviour, everywhere. The pricing workbook's no-arbitrage checks (sum of YES asks > 1, sum of YES bids < 1, mids sum to exactly 1, YES/NO complements per outcome) run as runtime assertions that halt the market and page on-call when violated. • A stale feed pauses the market; an unreachable engine produces a clean order rejection. The system never fails open. • The settlement service. Mid-game TIE/GTL resolution with correct no-intermediate-tie sequencing, final-buzzer KTL resolution, a maturity fee on profit, and finalisation only after reconciliation against official scoring — plus an admin manual-override and market-void path for overtime, voided games, and league scoring corrections. • Infrastructure as code. AWS EKS, RDS multi-AZ, Terraform; autoscaling for bursty, schedule-driven game-night traffic; managed failover primitives. The engine is single-threaded by design (determinism), so it scales horizontally by game — each game's markets are independent — rather than by threads. • Risk as a first-class operational signal. The maker's live exposure — the L2 norm of its [KTL, TIE, GTL] position vector, residual absorption (U), distance to the throttle cap, and cancel rate — is monitored and paged like infrastructure health. • Delivery leadership. Hard integration checkpoints so workstreams never diverge, a pre-agreed descope ladder that flexes scope while protecting the ledger / determinism / fail-safe guarantees, the failure drills, and the launch-readiness review with the client.

🎯 Requirements

• Senior, hands-on experience building financial, exchange, trading, or ledgered systems where correctness and auditability are first-class — payments, brokerage, betting/wagering, or order-matching backgrounds all fit. • Deep practical command of double-entry accounting systems and the discipline of deriving balances from an immutable record. • Real experience with event sourcing / CQRS: sequencers, append-only logs, snapshot-and-replay, and why determinism matters for both recovery and testing. • Strong PostgreSQL depth — serializable isolation, replication, recovery objectives — and production ownership of AWS (EKS/Kubernetes, RDS), Terraform, multi-AZ failover. • TypeScript / Node.js fluency; the stack is TS end-to-end and the engine spec translates directly from the client's existing JS/TS code, so discrepancies surface fast. • A track record of leading small senior teams to a fixed external commitment and making the scope trade-offs that protect the core when something slips. • Calm, direct client communication — you'll run the scoping sessions (settlement edge cases, fee schedule, data-vendor selection) and the go/no-go review. • Nice to have: Prior work with a real-time matching engine or order book — ideally one with a maker/inventory-risk model (exposure caps, skew, unwinding). • Experience integrating a licensed sports-data feed (Sportradar / Genius Sports) or similar low-latency authoritative source; scraping is disqualifying for a money product. • Observability ownership at the SLO level (Datadog / PagerDuty / Sentry), including treating business-risk metrics as paged, first-class signals. • Familiarity with regulated/licensing-gated product paths (KYC/AML, responsible gaming, SOC 2) — relevant to the real-money roadmap that this architecture is built to absorb.
