Staff Software Engineer, Core Services

Location: United States (Remote), Canada (Remote)

Department: Engineering

Location Type: REMOTE

Employment Type: FULL_TIME

 
About The Team:
OneSignal powers billions of messages and HTTP requests every day. We’ve achieved this scale by pairing modern, high-performance data stores with efficient technologies such as Rust, creating reliable systems that maximize performance and resource utilization.

The Core Services team builds and operates the foundational services behind OneSignal’s platform, including our delivery pipeline, gRPC services, Kafka infrastructure, and other systems processing hundreds of thousands of events per second. You’ll work with technologies including Rust, gRPC, Redis, Kafka, Scylla, ClickHouse, Pulsar, PostgreSQL, and occasionally Golang and Ruby.

As OneSignal evolves into a fully autonomous platform, the Core Services team will build and scale the high-stakes services that our products and engineering teams rely on. As a Staff Software Engineer, you’ll lead significant projects and directly shape the reliability, performance, and future of our platform.
 
What You'll Do
  • Collaborate with engineers to architect and implement high-performance services that are durable and reliable
  • Participate in code reviews, design reviews, and production on-call rotation
  • Work together with the team to resolve production issues and ensure system scalability
  • Conduct data analysis, performance monitoring, and system optimization through benchmarking/profiling.
  • Work independently to drive experiments and solutions for business needs
  • Design synchronous and asynchronous APIs for communicating between services in a large distributed system
  • Design schemas for relational and non-relational databases

 
What You'll Bring:
  • 8+ years of experience working as a software engineer
  • Experience operating reliable production systems at scale
  • Experience writing high-performance code in a compiled language such as Rust, C/C++, or Golang
  • Ability to reason about how data flows through distributed systems
  • Experience using LLM-powered coding tools, such as Claude, to accelerate development, improve code quality, and enhance engineering workflows. 
  • Bias towards automating the boring stuff

 
We value a variety of experiences, and these are not required. It would be a added bonus if you have experience in any of the following: 
  • Experience with any of Redis, Kafka, Postgres, ClickHouse, gRPC
  • Experience profiling applications to improve performance in terms of time/CPU/memory
  • Experience debugging issues in distributed systems

The New York and California base salary for this full time position is between $200,000 to $220,000. Your exact starting salary is determined by a number of factors such as your experience, skills, and qualifications. In addition to base salary, we also offer a competitive equity program and comprehensive and inclusive benefits.
