Senior Software Engineer, Platform Engineering - Golang

Role Description

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 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 growth, they are bolstering their team to build the scalability needed to keep pace with demand.

As a key member of the platform engineering team, you will design, build, and optimize Go-based services that power core infrastructure:

• 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.

Qualifications

• 5+ years of software engineering experience, including at least 3 years building and operating Go services in production.
• 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.

Requirements

• Familiarity with blockchain data flows or Web3 development tooling is a bonus.
• You’ve contributed to open-source Go libraries or large-scale projects is a bonus.
• You have experience mentoring junior engineers or conducting thorough code reviews is a bonus.
• You have worked with container orchestration (Docker, Kubernetes) in production environments is a bonus.
