Role
Who you are
- 5+ years of professional software development experience, with a strong emphasis on backend systems
- Deep proficiency in Go, and comfort working in a polyglot environment that may include JavaScript, Clojure, and bash
- Proven experience building and maintaining production-quality distributed systems at scale
- Strong software testing skills with experience writing comprehensive unit, integration, and end-to-end tests that ensure code quality and reliability
- Familiarity with Kubernetes and modern deployment practices
- A production-first mindset—you're comfortable monitoring live systems and resolving issues in real time
- A pragmatic approach to software engineering—using just enough code to solve the problem, while keeping complexity in check
Desirable
- Experience with AI/ML technologies or integrating LLMs into applications
- Knowledge of machine learning for test selection, build optimization, or predictive CI/CD insights
- Background in using AI to enhance developer tools or automate CI/CD processes
- Understanding of LLMs and their application in developer workflows
What the job involves
- Design and build reliable, observable, zero-downtime distributed systems that serve millions of builds across thousands of customers
- Collaborate with cross-functional teams to shape and refine foundational capabilities
- Own your work from concept to deployment and beyond—digging into production issues using tools like Honeycomb, Datadog, Grafana, and Rollbar to ensure system health
- Write clear, maintainable, and well-documented Go code, with observability and long-term maintainability built in
- Participate in architectural decisions and technical strategy development
- Lead complex projects and initiatives from inception to completion
- Mentor junior and mid-level engineers and provide technical guidance to the team
- Contribute to a culture of continuous improvement, helping your team and our customers succeed
- Continue your professional growth through increased technical scope, leadership opportunities, and strategic impact, supported by mentorship from experienced leaders and exposure to complex engineering challenges across the organization
Our take
Engineering has seen the rise of agile, containerisation and DevOps over the last few years. As a result, the idea of continuous integration and continuous delivery (CI/CD) has grown to be an important part of the engineering space. CircleCI is one company that taps into this field, offering a lightweight and open service.
There are now a lot more companies that have a culture of continuous delivery. CircleCI specifically helps automate all the steps that occur between the time developers make changes to the code and when the application gets in front of the customer. The company has a strong tailwind from this macro trend and their product is loved by engineers, putting them in a strong place to build a strong business.
Services in the sector have grown constricted and cost-heavy, but in 2022, CircleCI debuted a free tier service for engineering teams in a move away from this. By offering flexibility across an increased number of major platforms, including Docker, Windows, and MacOS, the company works towards its ultimate aim to empower technology-driven organisations.
