Site Reliability Engineer

Role Roadmap We are building a next-generation financial ecosystem (think NYSE or CME from scratch). We are a small team, which means your responsibilities scale very rapidly, and your contributions are clear and visible, not marginal. There is still a lot of green field at Kalshi and a lot of it (including entire systems) can be yours. What you’ll do Improve observability, reliability and availability by defining and measuring key metrics. Build automation and improve systems to eliminate toil and operations work. Collaborate with our core infrastructure team to performance tune and optimize our cloud deployments. (Think Docker, Terraform, Kubernetes, EC2, etc.) Collaborate with product teams to reduce service disruptions and automate incident response. Proactively find and analyze reliability problems across our business units and stack, then design and implement software to create step-function improvements. Educate, mentor and hold accountable the engineering team to improve the reliability of our systems and make reliability a core value of the Kalshi engineering culture. Write high quality, well tested code to meet the needs of your customers. Debugging extremely difficult technical problems, and making systems and products both work better and are easier to deploy, own, operate and diagnose. Review all feature designs within your product area and across the company for cross-cutting projects. Be an owner of the security, safety, scale, operational integrity, and architectural clarity of these designs. Build integrations with 3rd party vendors. Participate in an on-call support rotation to provide timely troubleshooting and resolution of urgent issues. What we’re looking for Attributes: You have at least 4 years of experience in software engineering. You’ve designed, built, scaled and maintained production services, and know how to compose a service oriented architecture. You write high quality, well tested code to meet the needs of your customers. You’re passionate about building an open financial system that brings the world together. You possess strong technical skills for system design and coding. Excellent written and verbal communication skills, and a bias toward open, transparent cultural practices. Strong skills around observability, debugging and performance tuning. Strong interpersonal skills working with engineers from junior to principal levels Demonstrated critical thinking under pressure. A willingness to dive into understanding, debugging, and improving any layer of the stack. On-call availability to ensure swift resolution of issues. Bonus points Experience designing and building reliable systems capable of handling high throughput and low latency. Experience with Datadog. Experience with Rust, Go and Terraform. Experience with AWS, GCP, or Azure. Experience working in a highly regulated environment. Experience writing company-facing blog posts and training materials. Our Culture Meritocracy is at our core, and we value people who take ownership and figure (usually hard) things out. We dream big. We love our craft deeply and are proud of what we put out in the world. We are committed to our vision of building something big… but also useful: a product that brings more truth through the power of markets. Kalshians are Kalshi’s most important asset: we pick Kalshians carefully, so we trust them fully on day 1. NYC Pay Transparency Disclosure: Salary Range: $100,000 to $250,000 annually plus equity and benefits. This salary range is based on the current available market data and represents the expected salary range for this role. Kalshi has minimal hierarchy and few titles, but a broad range of experience is represented within roles.
