📋 Description

• Own the architecture and technical roadmap for how customers access and use Trading API, including identity, authentication, authorization, permissions, account models, partner OAuth, and customer-facing trading and account-management applications. • Design access models for complex account structures, including multiple users, sub-accounts, entity and advisor accounts, and delegated API and agent access. • Lead technical delivery of Trading API customer applications, including real-time market data, order entry, and positions and order views. • Drive migration from legacy monolith endpoints to a dedicated application backend with clear API contracts. • Set security standards for customer-facing systems, including session and credential handling, MFA, passkeys, OAuth flows, rate limiting, input validation, and security findings response. • Establish safe delivery standards through feature flags, staged rollouts, preview environments, testing strategy, and production observability. • Partner with Product, Design, Compliance, Security, Brokerage Operations, and engineering teams. • Lead design reviews, mentor engineers, and raise engineering standards. • Act as technical escalation point for production issues and drive durable incident prevention.

🎯 Requirements

• 8+ years of software engineering experience, with significant time on both backend services and customer-facing applications. Evidence of scope and ownership matters more than a strict year count. • Proven ownership of a production system where a defect could expose customer data, grant the wrong access, or cause financial loss. • Deep experience with authentication and authorization: OAuth 2.0 and OpenID Connect, session and token management, MFA, and role- or attribute-based permission models. • Strong backend expertise in Go, or deep experience in Java, Kotlin, C#, or Rust and a clear willingness to work primarily in Go. • Strong frontend experience with TypeScript and React, including complex, state-heavy applications. • Solid knowledge of relational databases (PostgreSQL preferred), API design (REST and gRPC), and service-oriented systems running on Kubernetes. • Demonstrated care for correctness and security: threat modelling, testing strategy, edge-case analysis, and safe production rollout. • Clear communication with engineers, designers, product managers, and compliance and security partners, including when requirements are ambiguous or still being defined. • Track record of technical leadership and mentorship across teams. • Product-minded approach and effectiveness as a teammate. • Experience with real-time data over WebSockets or other streaming protocols is strongly preferred.
