About the Role

 

This opportunity is for a senior-level backend engineer focused on building and scaling high-performance data infrastructure. You will design and operate distributed systems that power large-scale applications, handling millions of queries per second across modern bare-metal environments.

 

This role requires deep expertise in Go and large-scale backend systems. You will contribute to mission-critical services that operate across dense, high-capacity infrastructure, ensuring performance, reliability, and scalability at extreme scale.

 

Work Arrangement: Fully Remote (U.S.-based). Overlap with Pacific Time required; proximity to Seattle is a plus.

 

What You’ll Do

 

* Scale production Go services to support hundreds of millions of users
* Design and build mission-critical data infrastructure powering API traffic
* Architect systems capable of operating across tens of terabytes of RAM and thousands of CPU cores
* Develop and maintain distributed backend services handling high query throughput
* Optimize performance across storage layers, including high-capacity NVMe systems
* Collaborate with engineers to improve reliability, observability, and system resilience
* Participate in design discussions and contribute to architectural decisions
* Continuously evaluate and improve infrastructure scalability and efficiency

 

Qualifications

 

* Strong foundational programming and software engineering skills
* Extensive professional experience with Go (5+ years preferred)
* Experience building and operating scalable backend systems handling high throughput (1M+ operations per second)
* Deep understanding of operating systems, networking, and storage systems
* Significant experience with relational databases such as Postgres, MySQL, or SQLite
* Experience with distributed data stores such as Cassandra, Scylla, Redis, or ClickHouse
* Experience working with search systems such as Elasticsearch
* Ability to thrive in a small, fast-moving engineering team
* Strong communication skills and the ability to work independently

 

Preferred Experience

 

* Experience building infrastructure for large-scale social or consumer applications
* Experience working in high-density bare-metal environments
* Familiarity with protocol-driven or federated systems architectures

 

Pay: $170,000 - $230,000 per year. Equity may be included as part of total compensation.

 

Work Environment & Benefits

 

* Fully remote team with required overlap with Pacific Time working hours
