Your opportunity

We’re supporting a remote-first team responsible for a comprehensive open-source developer platform that has processed over $5 billion in transaction volume. A pioneer in their space, their unified API and SDK layer simplifies the onchain developer experience and underpins games and apps used by millions. Built on scalable, fault-tolerant services, the platform delivers indexing, relaying, and analytics pipelines engineered for millions of requests per minute. Now, backed by top-tier investors and fueled by continued user growth, they are bolstering their team to build the scalability needed to keep pace with demand.

As a key member of the core platform engineering team, you will face unique situations and scaling challenges seen by few others (previous examples include hitting Postgres limits and discovering bugs in open-source libraries even the original developers hadn’t seen). Thousands of developers will rely on you to design, build, and optimize Go-based services that power core infrastructure, including indexers, relayers, metadata aggregation, payment proxies, and marketplace APIs, ensuring they perform reliably at scale.

Key responsibilities 

• Own core infrastructure services: architect, develop, and maintain Go-based services for data indexing, transaction relaying, metadata aggregation, and marketplace APIs; extend and evolve the platform toolchain for future extensibility

• Scalable, fault-tolerant design: design and implement services with high availability and resilience to handle millions of requests per minute; build robust architectural foundations so future engineers can build on your work with ease

• High-throughput optimization: tune databases and service configurations to support surging workloads and complex queries

• Cross-functional collaboration: partner with SDK, R&D, and product teams to define clear service interfaces; support internal teams consuming platform APIs; contribute to documentation and developer tooling used by clients

• Maintenance & innovation: rotate between refactoring, maintenance, and new feature development to balance platform stability with rapid delivery of capabilities

• Open-source contributions: contribute to shared libraries and tooling used across the ecosystem

Your know-how

• 7+ years of software engineering experience

• Deep expertise in designing and maintaining production-grade backend services at scale

• Experience working with distributed systems

• Practical experience with large-scale relational databases (e.g. Postgres)

• Hands-on experience with cloud infrastructure providers such as AWS, GCP, or Azure 

• A growth mindset; you actively seek out new technologies and enjoy solving complex problems

• Excellent communication skills

It’s a bonus if

• You have familiarity with blockchain data flows or Web3 development tooling 

• You’ve contributed to open-source Go libraries or large-scale projects

• You have experience working at a platform-first company, building products for other developers

• You have experience mentoring junior engineers or conducting thorough code reviews

• You have worked with container orchestration (Docker, Kubernetes) in production environments
