Role RoadmapAs a member of Kalshi's engineering team, you'll help build the next-generation financial ecosystem-similar in ambition to creating an NYSE or CME from scratch. As part of a small, fast-moving team, your responsibilities will scale rapidly, and your impact will be highly visible. Much of Kalshi's infrastructure is still greenfield, and entire systems can be yours to design, own, and evolve.
What You'll Do- Improve observability, reliability, and service availability by defining and measuring key metrics
- Build automation and systems that eliminate toil and reduce operational burden
- Collaborate with core infrastructure engineers to performance-tune and optimize cloud deployments (Docker, Terraform, Kubernetes, EC2, etc.)
- Partner with product teams to minimize service disruptions and automate incident response
- Identify and analyze reliability problems across the stack, designing and implementing software for significant, long-term improvements
- Mentor engineers and drive a culture where reliability is a core engineering value
- Write high-quality, well-tested code that supports internal and external customer needs
- Debug complex technical issues and improve system usability, operability, and diagnosability
- Review feature designs across the company and ensure security, safety, scalability, and architectural clarity
- Build and maintain integrations with third-party vendors
- Participate in on-call rotations to troubleshoot and resolve urgent issues
What You Bring- 4+ years of software engineering experience
- Experience designing, building, scaling, and maintaining production services and service-oriented architectures
- Strong system design, coding, debugging, performance-tuning, and observability skills
- High-quality coding practices with strong testing discipline
- Excellent written and verbal communication; comfort working transparently across teams
- Strong interpersonal skills across junior-to-principal engineering levels
- Ability to think clearly under pressure and dive into any layer of the stack
- Passion for building an open financial system that connects the world
- Willingness to participate in on-call rotations and swiftly resolve issues
Bonus Points:- Experience designing highly reliable, high-throughput, low-latency systems
- Experience with Datadog
- Experience with Rust, Go, and Terraform
- Experience with AWS, GCP, or Azure
- Experience operating in regulated environments
- Experience writing training materials or company-facing engineering content
