Role 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. - Own and build the money-grade double-entry ledger (PostgreSQL, serializable, multi-AZ, RPO 0): - Balances derived from postings - Idempotency on every mutation - Books that reconcile to the cent - A reconciliation job that pages on any discrepancy - Own determinism and recoverability: - A single sequencer per market - An append-only event log - Snapshot-plus-replay recovery that produces bit-identical state - Enforce fail-safe behaviour everywhere: - Pricing, risk, and no-arbitrage invariants as runtime assertions that halt the market and page - Stale data pauses - An unreachable engine yields a clean rejection — never fail open - Own the settlement service: - Event-time resolution with correct sequencing of dependent outcomes - Fictionalization only after reconciliation against an authoritative data source - An admin override / market-void path - Own infrastructure as code (AWS EKS, RDS multi-AZ, Terraform) and scaling for bursty, schedule-driven traffic — horizontally by market, since the engine is single-threaded by design - Set the platform architecture, run hard integration checkpoints so work-streams never diverge, and maintain a descope ladder that protects the ledger, determinism, and fail-safe guarantees under pressure - Lead a small senior team across engines, platform, and core & infrastructure; own stakeholder communication and go/no-go decisions Qualifications - Senior, hands-on experience building financial, exchange, trading, or ledgered systems where correctness and auditability are first-class - Deep command of double-entry accounting systems and the discipline of deriving balances from an immutable record - Event sourcing / CQRS in practice: sequencers, append-only logs, snapshot-and-replay, and why determinism matters for recovery and testing - Strong PostgreSQL depth (serializable isolation, replication, recovery objectives) and production ownership of AWS (EKS/Kubernetes, RDS), Terraform, and multi-AZ failover - TypeScript / Node.js fluency — the platform is TS end-to-end with shared types across engine, API, and frontend - A track record of leading small senior teams to a commitment and making the scope trade-offs that protect the core when something slips - Calm, direct stakeholder communication - Real-time matching engine or order-book experience, ideally with a maker / inventory-risk model - Integrating an authoritative, low-latency real-time data feed - Observability ownership at the SLO level (Datadog / PagerDuty / Sentry), treating business-risk metrics as paged, first-class signals - Familiarity with regulated / licensing-gated product paths (KYC/AML, responsible-use controls, SOC 2) Benefits - In addition to a market competitive compensation, we have a reward philosophy that expands beyond this - Fully remote - Opportunity to work with a truly global team - Flexible timings.
