Site Reliability Engineer, UK

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 at Kosli, you will play a pivotal role in embedding reliability into the core of our applications and infrastructure. This position combines expertise in infrastructure management, data analysis, observability, and platform development to ensure our services are robust, secure, and scalable. You will work closely with development teams to integrate reliability into the application lifecycle, leveraging your skills in Python and other languages to build resilient systems.

As Kosli continues to grow, our focus on reliability and scalability becomes increasingly important, and we need talented engineers who can bridge the gap between infrastructure and application reliability.

Key Responsibilities

• Design and Implement Reliability: Collaborate with development teams to integrate reliability into application design and development, focusing on building fault-tolerant systems.
• Cloud Infrastructure Management: Manage and evolve Kosli’s cloud infrastructure using Terraform and AWS, ensuring it supports scalable and reliable application deployments.
• Security and Compliance: Lead security implementation and compliance checks across our infrastructure, ensuring alignment with industry standards.
• Observability and Monitoring: Own and improve our monitoring and observability stack (Prometheus, Grafana & RollBar to name a few) to provide actionable insights that inform reliability improvements.
• CI/CD Pipelines: Take ownership of build and deployment pipelines using GitHub Actions, ensuring smooth and reliable software delivery.
• On-Premise Solutions: Lead the development of our on-premise solution for customers, focusing on reliability and scalability.
• Shared Infrastructure Components: Develop and maintain shared infrastructure components for customers, including Terraform modules and shared GitHub Actions and GitLab Pipelines.
• Service Level Management: Use your experience to assist in implementing and driving adoption of Service Level Agreements (SLAs), Service Level Objectives (SLOs), and error budgets to ensure alignment with business objectives and customer expectations.

You Might Be a Great Fit If You Have

• Experience with Large-Scale Systems: A background in operating large-scale data platforms or applications with a focus on reliability.
• Infrastructure-as-Code Expertise: Deep expertise with Terraform and AWS cloud platforms.
• Monitoring and Observability Skills: Experience building and maintaining monitoring/observability stacks to drive reliability improvements.
• CI/CD Proficiency: Proficiency with CI/CD pipelines, especially GitHub Actions and GitLab.
• Reliability Track Record: A track record of improving system reliability and deployment processes.
• Programming Skills: Familiarity with Python, Go, and shell scripting, with a focus on using these skills to enhance application reliability.
• SRE Practices and Service Levels: Knowledge of modern SRE practices, including the implementation of SLAs, SLOs, and error budgets to manage service reliability and availability.
• Passion for Quality Infrastructure: Passion for quality infrastructure code and modern SRE practices that prioritise reliability and scalability.
• Problem-Solving and Collaboration: Strong problem-solving abilities, attention to detail, and clear communication skills to collaborate effectively in a distributed team.
• Curiosity and Enthusiasm: Enthusiasm for being an early user of tools you help build and curiosity about regulated industries and compliance requirements.
