Site Reliability Engineer, Europe

Do you want to shape the future of software delivery in the financial services industry?

Kosli is looking for a Site Reliability Engineer to join our growing team. As part of a fast-paced startup, this role is about building and maintaining a large scale data and compute cloud infrastructure that powers our SaaS platform.

About Kosli

Kosli’s mission is to change the way we deliver software in regulated industries. The world is built on mission critical software. It calculates our bank balance. It drives our cars. It diagnoses our illnesses.

We want to empower the engineers who make this software.

When you’re regulated, every change needs to be controlled. This typically means manual paperwork, meetings, delays, and more risk.

We believe this should be automated, and we’re building technology to make this happen.

We are an ambitious group of people and we want you to join us.

We are funded by leading VC investors such as Heavybit (investors in Snyk, LaunchDarkly, CircleCI, Netlify, Tailscale).

About the Role

As a Site Reliability Engineer, you will be responsible for building and maintaining Kosli’s infrastructure, ensuring our platform’s reliability, and developing solutions for both cloud and on-premise deployments. This role combines infrastructure management, data, observability, and platform development to deliver a robust, secure and scalable service.

As Kosli continues to grow, so does our data and cloud infrastructure.

Key Responsibilities

• Manage and evolve Kosli’s cloud infrastructure using Terraform and AWS
• Lead security implementation and compliance checks across our infrastructure
• Own and improve our monitoring and observability stack, ensuring it delivers actionable insights
• Take ownership of build and deployment pipelines using GitHub Actions
• Lead the development of our on-premise solution for customers
• Develop and maintain shared infrastructure components for customers including:
• Terraform modules
• Shared GitHub Actions and GitLab Pipelines

You Might Be a Great Fit If You Have

• Experience operating large scale data platforms
• Deep expertise with infrastructure-as-code (Terraform) and AWS cloud platform
• Experience building and maintaining monitoring/observability stacks
• Proficiency with CI/CD pipelines, especially GitHub Actions and GitLab
• A track record of improving system reliability and deployment processes
• Familiarity with Python, Go and shell scripting
• Passion for quality infrastructure code and modern SRE practices
• Strong problem-solving abilities and attention to detail
• Clear communication skills and ability to collaborate in a distributed team
• Enthusiasm for being an early user of tools you help build
• Curiosity about regulated industries and compliance requirements

What We Offer

• Competitive salary and generous equity - we want you to own part of what you’re building
• Remote-first environment with a focus on flexibility
• Regular team meet-ups across Europe
• Budget for learning and development
• A voice in shaping both our product and our company
• Real impact on how some of the world’s largest financial institutions deliver software
