About the Role
We are looking for a Senior Backend Engineer to join our core engineering team and help build high-
throughput, low-latency services that power real-time trading at scale. What We’re Looking For
You are someone who has built backend systems in a regulated, high-stakes environment — ideally fintech, brokerage, payments, or banking. You think in terms of system reliability, data correctness, and operational
excellence. You take ownership of services end-to-end: from design and implementation through deployment, monitoring, and incident response. You communicate clearly, make pragmatic trade-offs, and hold yourself and
your peers to a high engineering bar. What You’ll Do
• Design, build, and own backend microservices for a real-time trading platform — from API contracts
through to production observability. • Work with databases, caches, and event-driven architectures to ensure high availability and data
consistency across distributed systems. • Build integrations with third-party financial services — clearing, settlement, identity verification, and
payment rails. • Define and enforce engineering standards — code reviews, testing strategies, API design conventions, and incident response processes. • Collaborate with product, design, and cross-functional teams to translate business requirements into
well-scoped technical deliverables. • Participate in on-call rotations and own production reliability for the services you build. • Mentor junior engineers and contribute to a culture of technical excellence and continuous improvement. Must-Have
• 5+ years backend engineering experience with Golang and Java in production. • Strong experience with PostgreSQL, Redis, and event-driven messaging (Kafka, NATS, or RabbitMQ). • Experience building and maintaining REST/gRPC APIs at scale with proper error handling, rate limiting, and versioning. • Understanding of financial systems — ledgers, reconciliation, order lifecycle, or payment processing.
• Experience with microservices architecture, API gateways, and service-to-service communication
patterns. • Familiarity with CI/CD pipelines, containerization (Docker/Kubernetes), and cloud infrastructure (AWS or
GCP). • Strong debugging and incident-response skills in distributed systems. Nice-to-Have
• Prior experience at a brokerage, wealth-tech, neo-bank, or payments company. • Experience with clearing broker integrations or introducing broker models. • Knowledge of compliance and regulatory requirements for cross-border financial products. • Experience with search infrastructure (Typesense, Elasticsearch). • Background in performance engineering — profiling, load testing, and latency optimization.
