7 days ago
We are looking for a Senior Software Engineer to join the Developer Tools Team. In this role, you will bring your expertise in programming languages and ecosystems to our distributed team of engineers from various technical disciplines. You will help to build, maintain, and support client libraries and framework integrations. An interest in working across a range of projects and programming languages, with a particular focus on C#/.NET and the wider Microsoft developer ecosystem is essential. Ideally, you will also have experience developing software in an open-source environment.
The Developer Tools Team is primarily responsible for creating libraries, SDKs, and other tools that simplify the integration of the Elastic product suite into user applications. Your role will involve developing and maintaining this software, engaging with developer communities, and contributing to both team-wide projects and cross-team collaborations.
You will be working on fully open sourced code that is embedded within user applications, so will need to understand the implications of writing software in the open, versioning and managing product releases, and interacting with users directly in a public setting.
Prior experience with the Elastic product suite is not essential, but is beneficial.
What You Will Be Doing- You'll be developing, maintaining, and supporting libraries and third-party integrations for the Elastic Stack, working in a mixture of languages including C#.
- You'll participate in the design and development of team-wide projects.
- You'll support users through GitHub issues, forums, and official support channels.
- You'll collaborate with maintainers of external projects (e.g., GenAI frameworks) to facilitate integration with the Elastic Stack.
- You'll represent Elastic within relevant communities and ecosystems.
- Proven experience in building, releasing, supporting and maintaining software products for a broad user base
- Minimum 8 years of software engineering experience
- Knowledge of client-server networking, HTTP, and RESTful APIs
- Knowledge of developing software within an open-source environment
- Knowledge of industry best practices in software engineering
- A strong focus on usability and developer experience
- A genuine interest in technology and an active interest in exploring multiple programming languages
- Excellent communication, collaboration, and interpersonal skills.
- A willingness and ability to work as part of a remote, globally distributed team
- Clear thinking, self-motivation, and the ability to learn and work independently
- A connection to tech communities through open source projects, blogs or talks (nice to have)
- Prior experience of Elastic products (nice to have)
