Software Engineer 3

In practice, we build a platform for other engineers. Our users are developers and platform teams who expect self-service, sensible defaults and APIs that behave predictably. If you have built an internal developer platform, a Kubernetes controller, or any system whose customers are other engineers, you will recognise the problems we work on.

No prior experience with MongoDB is required. You will meet most of the team during interviews, and we pride ourselves on being an inclusive, collaborative group that Builds Together. Our core engineering values are Context, Predictability, Transparency, Focus and Craftsmanship.

This role can be based in our Dublin office, Cork office or remotely within Ireland.

The role

We are looking for a Software Engineer to join the Kubernetes Capabilities squad and help decide which MongoDB capabilities our users get on Kubernetes and how they work. You will own significant capabilities from design to production, make sound technical decisions under ambiguity, and raise the engineering bar of the team through design, review and mentorship.

Experience we value

What matters most is that you have built platforms, not only operated them. We value experience from any of these backgrounds:

* Building Kubernetes controllers, operators, CRDs, admission webhooks or other extensions against the Kubernetes API
* Building internal developer platforms: self-service provisioning, golden paths, platform APIs, CLIs or developer portals used by other engineering teams
* Building developer-facing infrastructure products such as SDKs, managed services, CI/CD systems or cloud provisioning tooling

Responsibilities

* Lead the design and delivery of new capabilities in our Kubernetes operators, from technical design through production support
* Work with Product and the teams behind MongoDB features to turn them into Kubernetes-native APIs our users can adopt
* Write technical designs that weigh trade-offs clearly and bring the team and stakeholders to a decision
* Shape our platform APIs with our users in mind: predictable, self-service and safe to operate
* Mentor engineers through pairing, code review and design feedback
* Partner with our platform squad, Support, Docs and other engineering teams, and help resolve complex customer issues
* Improve how the team works, including testing strategy, release quality and developer experience

Requirements

* Strong core software engineering skills and several years building production software in a modern language; we mostly use Go
* Proven experience building a platform for other engineers, such as Kubernetes controllers and operators, an internal developer platform, or developer-facing infrastructure products
* Deep working knowledge of Kubernetes, including its API model, reconciliation and the operational realities of running workloads on it
* Experience designing, testing and operating distributed systems in production
* A track record of leading projects through ambiguity and delivering them end to end
* Strong written communication, including technical design documents

Nice to have

* Experience with controller-runtime, kubebuilder or contributing to Kubernetes ecosystem projects
* Experience with multi-cluster Kubernetes, networking or service mesh
* Experience running stateful workloads or databases on Kubernetes
* Experience with a major public cloud provider

What is in it for you

* Generous compensation package (top-range salary, equity, comprehensive benefits)
* A diverse, highly collaborative team that values shipping fast and clean
* Time to learn on the job and grow into new technologies
* A high level of independence, focused on results rather than the appearance of work
