From the original posting

The Kubernetes teams make running MongoDB in and from Kubernetes so frictionless that it is the default database choice for cloud-native applications. Our operators let developers and platform teams provision, scale and operate MongoDB through Kubernetes-native APIs, in their own clusters or in MongoDB Atlas.

You will join the Kubernetes Capabilities squad. Our sister squad builds the shared platform layer of the MongoDB Controllers for Kubernetes; we build the capabilities on top of it that users actually adopt. That means bringing MongoDB features such as Search and Vector Search to Kubernetes, extending what our users can deploy and manage declaratively, and owning the Atlas Kubernetes Operator. Our work starts with a user problem and ends with a Kubernetes API that solves it.

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

With offices worldwide and over 67,000 customers, including AI-native startups and approximately 75% of the Fortune 100, relying on MongoDB for their most important applications, we’re powering the next era of software.
