Job DescriptionCareer Renew is recruiting for one of its clients a Senior Golang Engineer - Crypto - this is a fully remote role for US/Europe based candidates. Salary range: 200-275K USD yearly plus benefits. We are a tiny team working on low-latency systems, live state, bursty traffic, and hard backend problems that have to stay correct under pressure. This is not a role for someone who wants a narrow ticket queue or a lot of process. It is for someone who wants real ownership, real scale, and real consequences. We’re looking for a Senior / Staff Backend Engineer with deep Go expertise and serious distributed systems experience to help build and operate the backend systems that power us. This person will own critical backend infrastructure end-to-end: blockchain read state, indexing pipelines, caching, database performance, service reliability, observability, and incident response. You should be comfortable stepping into an existing Go backend, understanding it quickly, and reshaping it into something that can handle launch-scale traffic and beyond. You should be fast, opinionated, highly autonomous, and product-minded. We use AI heavily to accelerate execution, but we expect engineers to drive architecture and decisions themselves. We want people who use AI as leverage, not as a substitute for judgment. What you’ll do * Own core backend systems powering our user-facing product * Design, build, and operate low-latency Go services that serve critical application and blockchain-related read state * Improve and harden our indexing, caching, database, and service architecture for scale, correctness, and reliability * Design systems that can absorb highly bursty traffic and recover cleanly under failure * Own observability across logs, metrics, tracing, alerting, profiling, and production debugging * Be directly involved in incident response, uptime, scaling, and backend reliability * Work closely with the founders on architecture, product shape, and technical tradeoffs * Propose better systems, better abstractions, and better product behavior instead of waiting to be told what to build * Help set the bar for backend engineering as the company grows What we’re looking for * Deep expertise in Go, including concurrency, context cancellation and deadlines, race detection, profiling, and strong testing practices * Proven experience building and owning production, user-facing, low-latency backend systems at meaningful scale * Proven experience building systems that handle bursty or highly variable traffic patterns * Strong distributed systems fundamentals, especially correctness under failure: idempotency, retries, ordering, consistency tradeoffs, caching, backpressure, and recovery * Strong database fundamentals, including schema design, transactions, indexing, query tuning, and performance debugging * Strong observability and production debugging skills across logs, metrics, tracing, and profiling * Experience operating production systems directly, including on-call and live incident response * Strong product ownership and the ability to independently drive system design, implementation, and operational quality * Comfort in a small, high-autonomy, docs-heavy, async-first startup environment * Strong infrastructure fluency across Docker, Kubernetes, AWS and/or GCP, and modern cloud deployment systems Bonus points * Experience with real-time systems such as websockets, pub/sub, streaming, or event-driven architectures * Strong security instincts and experience hardening backend systems * Crypto or Solana experience Who tends to do well here * Fast debuggers * Engineers who like ambiguity instead of needing everything pre-shaped * Builders who want to own a product surface, not just contribute code * People who move quickly without being sloppy * Engineers with strong opinions who can defend tradeoffs clearly * People who are comfortable working outside a narrow role when the company needs it Who usually won’t like this role * Engineers who need a lot of structure, layers of management, or tightly scoped ownership * People who want to stay strictly inside one lane * People who are uncomfortable being close to production * People who let tools make decisions for them instead of using judgment Why this role is interesting * You’ll join a very small team with outsized ownership from day one * You’ll work on real-time, low-latency backend problems that are technically hard and operationally meaningful * You’ll help shape the architecture early, while core decisions still matter * You’ll have direct influence over the product, not just the codebase * You’ll get equity and the chance to help build one of the most interesting companies in prediction markets from an early stage Compensation & Package * tokens + equity
