# Senior Systems Engineer > Raydar · New York, United States · Full-time · Posted 2026-10-05 **Salary:** USD 200,000–300,000 **Workplace:** on_site ## Description About the company Our client is a fast-growing software company. The role Raydar is recruiting for this role on behalf of our client. Hands-on senior individual contributor who designs and delivers core infrastructure software for a large compute environment. Works side by side with technical leadership and a compact group of engineers, with ownership from initial concept through live operation. What you'll do \- Architect, build and scale infrastructure software that runs across a large pool of physical servers. \- Take charge of difficult storage, networking and scheduling problems as demand and capacity grow quickly. \- Partner with technical leaders and a small team of engineers to solve open-ended infrastructure problems from the ground up. \- Write and tune performance-sensitive code in systems languages, prioritizing speed, correctness and dependability. \- Drive infrastructure initiatives from first design to production rollout, supporting new product capabilities and bigger accounts. \- Use AI coding assistants to speed up delivery and automate parts of the engineering workflow. ## Requirements What we're looking for \- At least 5 years of experience creating and growing distributed software close to the operating system. \- Direct experience with operating-system internals such as kernels, file systems or Linux building blocks, where you built core components yourself instead of stitching together managed cloud services. \- A history of owning substantial distributed systems in a startup or a small team with high autonomy, rather than in a large established company. \- Working knowledge of virtualization technology, such as QEMU or a lightweight hypervisor. \- Experience with distributed storage at significant scale. \- At least 2 years in an early-stage or high-autonomy company, owning a system from start to finish while it grew. \- Strong, practical fluency using AI coding agents in daily development. \- Comfort with ambiguity and with building things from nothing in a fast-moving setting. \- A strong individual contributor who can influence the direction of those around them. \- This is a builder role rather than a DevOps or SRE position. Bonus points \- Systems programming experience in a language such as Go or Rust. \- Familiarity with configuration management tooling. \- Experience founding or scaling a well-known startup, or a record of publications, patents or conference talks. ## Benefits Compensation and benefits \- Base salary: USD 200,000 to 300,000 per year \- Equity \- Health, dental and vision coverage \- Retirement plan with employer match \- Flexible time off \- Paid parental leave Location and work model \- New York City, New York, United States \- On-site, 5 days per week in the office \- Full-time ## Apply [Apply at Raydar](https://apply.workable.com/raydar/j/046C621FB3/apply) --- Powered by [Workable](https://www.workable.com)
