Senior Golang Developer (Trading Exchange)

Due to growth and expansion, we’re looking for a Senior Go Developer to join our Trading Exchange team. We are building an options exchange for the U.S. market — a full-featured exchange with a matching engine, order book, and all the necessary components. The project complies with all regulatory requirements for derivatives exchanges in the United States.

We have a fresh codebase (less than 3 years old), no deep legacy, and minimal technical debt.

What we're building:

• An exchange for trading high-risk instruments (binary options, event-based options, etc.).
• A proprietary clearing system, used not only by our exchange but also by our partner exchanges.
• An SDK for market makers working on our platform.

Our tech stack and development approach:

• Golang is our primary programming language.
• A service-oriented architecture with a custom transport layer (a variation of RPC) inherited from our parent company. We use service discovery and code generation.
• PostgreSQL is the main database. We actively use stored procedures but avoid implementing business logic or complex logic in them.
• We generate statically typed functions for calling procedures — no ORMs or SQL code generation tools.
• Performance is a priority at the architectural level, and we’re planning deeper optimization after implementing the core business logic.
• We actively write unit, integration, and end-to-end tests.
• We also work with CI/CD, Docker, Kubernetes, and GitLab. However, infrastructure-related tasks are not part of our day-to-day responsibilities — we have dedicated engineers for that.
• We follow Scrum with SAFe framework: 2-week sprints, daily stand-ups at 12:30 GMT+3, retrospectives, and grooming sessions.

Team composition: 3 Go developers, QA engineer, 2 AQA engineers, and a team lead.

Tasks

• Developing backend components of the trading system, including: the matching engine, the clearing system, and internal reporting storage.
• Designing and implementing protocols and services for external system integration.
• Maintaining and evolving the existing codebase: fixing bugs, improving architecture.
• Ensuring service performance and fault tolerance.
• Participating in code reviews and architectural discussions as part of delivering stable releases.

Requirements

• 5+ years of commercial backend development experience.
• At least 2 years of experience in Go development (commercial experience or pet projects).
• Hands-on experience with PostgreSQL: query optimization, partitioning, and replication setup.
• Strong understanding of multithreading principles and distributed service/microservice architecture.
• Deep understanding of performance aspects: differences between low latency, high load, and high performance, and the ability to balance these with code complexity.
• A thoughtful approach to ensuring consistency and determinism in the system — minimizing dependencies on timing, delays, and randomness.
• A mindset focused on resilience — system failures must not compromise data consistency.
• Fluent in Russian and English at B1 level or higher.

Nice to have

• Experience in the Forex/Fintech industry (especially in exchange-based trading).
• Practical knowledge of trading on traditional or crypto exchanges.
• Understanding of networking and basic internet protocols.
• Development experience in C++ or PHP.
• Experience using PL/pgSQL.

We offer

• Full-time remote work model (Service Provider), with the opportunity for full-time employment based on your location.
• Competitive remuneration.
• 20 paid days off annually.
• Flexible working hours.
• Training and development opportunities.
• A friendly, enjoyable, and positive work environment.
