We are hiring on behalf of our client, a leading innovator in the blockchain space who is seeking a Senior Golang Engineer to join their core backend team. Our client has developed a real-time parimutuel prediction market platform built on Solana, designed to integrate ultra-fast, 60-second to 30-minute prediction markets directly into livestream environments and web platforms.

Following a successful $1M pre-seed round in April 2026 led by prominent venture participants in the Solana ecosystem, the organization is scaling its infrastructure to handle high-concurrency, traffic patterns. As one of the first backend engineering hires, the successful candidate will own critical systems responsible for market creation, settlement, and automated payouts during high-stakes global livestream events.

• Concurrency & Performance: Implement sophisticated Go concurrency patterns to manage real-time data flow and high-frequency transaction processing.
• Infrastructure & Scaling: Manage and optimize distributed systems, ensuring idempotency, consistent ordering guarantees, and robust failure recovery.
• Observability: Lead production debugging efforts using logs, metrics, tracing, and profiling to maintain 24/7 system reliability.
• Technical Autonomy: Operate with a high degree of independence in a fast-paced startup environment, shaping the foundational architecture of a novel product category.

Requirements

• Expert Go Proficiency: Deep technical expertise in Go, including context management, race detection, profiling, and advanced testing practices.
• Distributed Systems Experience: Proven track record of building and owning user-facing, low-latency systems at scale, particularly under highly variable or "bursty" traffic.
• Database Mastery: Strong fundamentals in schema design, transaction management, indexing, and performance tuning for high-throughput applications.
• Startup Mentality: Comfort operating in a small, high-ownership environment with minimal process and a strong emphasis on shipping quality code.
• Modern DevOps: Experience with Docker, Kubernetes, and cloud-native scaling strategies.

Preferred Qualifications

• Experience with real-time architectures (WebSockets, Pub/Sub, event-driven systems).
• Familiarity with the Solana ecosystem or blockchain-based settlement.
• Background in financial systems, parimutuel mechanics, or prediction markets.
• Experience hardening backend systems against security vulnerabilities.

Benefits

• Competitive Compensation: Base salary range of $200,000 – $275,000 .
• Equity & Incentives: Comprehensive package including tokens and equity.
• Remote Flexibility: 100% remote
• Innovation: Opportunity to work on a first-of-its-kind product backed by top-tier strategic investors.
