Job Description
This full-time, on-site senior developer job is listed for the United Kingdom and works on the core and infrastructure side of Elasticsearch at Elastic. The team builds the shared platform features that keep the engine simple to use, fast, maintainable and secure. Its scope includes services, settings, scripting, the plugin model and the Painless scripting language, along with the logging and telemetry that make the engine observable. The group also orchestrates Elasticsearch in serverless environments and manages the CI/CD workflows used to deliver the product to serverless, cloud and self-managed customers.
The role is an individual contributor position with a leadership element, since the developer helps drive projects that span several teams. The ideal person is comfortable close to the codebase's low-level details and also lead technical conversations with a range of collaborators. Responsibilities include designing new scalable APIs and features, handling difficult performance and concurrency issues, and making cloud operations more transparent and easier to run.
The developer works in the open with the Elasticsearch group, customers and open source projects, and helps support engineers with harder problems. Ownership extends to operational investigations until the performance or stability problem is fully addressed. The listing gives a typical starting base range of CAD 128,300 to CAD 203,000, notes there is no variable pay, and says the role is eligible for Elastic's stock program. It also describes an employer-matched RRSP retirement savings account, with matching up to 6 percent of eligible earnings.
Responsibilities
- Help evolve the core infrastructure that Elasticsearch depends on
- Create automation that boosts developer productivity, including ways to fold agent-based tools into daily work
- Build new features and APIs that scale horizontally
- Work through complex performance and concurrency problems and recommend solutions
- Make Elasticsearch cloud systems easier to operate and observe
- Contribute in the open alongside the Elasticsearch group and external users
- Assist support engineers with difficult escalations
- Carry operational investigations through to resolution
Requirements
- Experience designing APIs and judging trade-offs
- Proficiency with algorithms and data structures
- Strong core Java, including its standard library, concurrency constructs and newer language features
- Experience with lower-level Java areas such as threading, parallelism and class loading
- Practical work with CI/CD tooling, including Buildkite, Argo CD and GitOps
- Experience directing large projects across engineering groups
- Ability to own work from design through delivery and to operate independently in a distributed setting
- Track record of using AI tools to speed development and debugging while staying responsible for results
Qualifications
- Knowledge of JDK internals such as modules, the memory model, garbage collection and caching
- Experience with OpenTelemetry or similar observability solutions
- Knowledge of Go
- Knowledge of containers and Kubernetes
- Familiarity with Gradle or Maven, with a preference for Gradle
- Background on a platform team or a developer productivity team
