Job description

Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale — unleashing the potential of businesses and people. The Elastic Search AI Platform, used by more than 50% of the Fortune 500, brings together the precision of search and the intelligence of AI to enable everyone to accelerate the results that matter. By taking advantage of all structured and unstructured data — securing and protecting private information more effectively — Elastic’s complete, cloud-based solutions for search, security, and observability help organizations deliver on the promise of AI.

What is The Role:

We're looking for a Senior Software Engineer to join our Streams UI team, where you'll have the chance to shape and enhance our user interface, making it more intuitive and engaging for our users. In this role, you'll work on Fleet. Fleet is the central management experience for Elastic Agent in Kibana. You'll also work on Streams. Streams is our new tool for handling log data. This includes ingesting, organizing, parsing, enriching, and setting retention for the data. You will be part of a skilled group of engineers and designers. You will contribute your expertise and learn from others. If you enjoy tackling complex challenges and want to make a meaningful impact on our product, we’d love to hear from you.

What You Will Be Doing:

• Design and implement intuitive user interface components that enhance user commitment, using TypeScript, React, and Node.js. Integrate front-end elements seamlessly with back-end services to ensure a smooth user experience. Conduct usability testing and gather user feedback to drive continuous improvements.
• Own complex, loosely-defined problems end-to-end: shape the approach, split the work if needed, make the key technical decisions, and deliver.
• Lead discussions on architecture and system design. During these discussions, consider trade-offs. Also, think about backwards compatibility, performance, and scale.
• Establish coding standards and ensure the team adheres to them throughout the development process. Promote reusable components to improve efficiency and implement automated testing and deployment to maintain code quality. Evaluate new technologies for potential integration and document best practices to facilitate team-wide knowledge sharing.
• Conduct thorough code reviews to ensure adherence to coding standards and best practices. Offer constructive feedback and identify potential security vulnerabilities in the codebase. Focus on maintaining code readability and facilitate discussions with team members to address any findings from the code review.
• Collaborate async across timezones with a fully-distributed team, working in the open on GitHub and in Slack.
• Partner closely with designers and product managers to apprehend user experience goals and translate their mockups into functional UI components. Ensure a consistent visual design across all UI elements. Participate in brainstorming sessions to generate innovative ideas for enhancing the user interface.

What You Bring:

• Solid production experience with full-stack JavaScript, preferably TypeScript; React on the front end and Node.js on the back end. Some experience with Reactflow is a plus.
• A track record of leading non-trivial projects end-to-end, with real design ownership and minimal guidance.
• Proficient architecture and system-design judgment, including in large, existing codebases.
• Successfully designed and launched multiple user interface components that significantly increased user commitment.
• You should have experience using AI-assisted development tools. These tools can help you develop features faster, fix complex systems, and improve existing codebases.
• Exemplary written and verbal communication, and a genuine excitement for async collaboration and knowledge-sharing.
• A multiplier mindset! You make the engineers around you better.
• A generalist streak and a user-focused mindset, with consideration for the people using your software.

Bonus Points:

• Experience with the Elastic stack, observability tooling, or log/data-ingestion pipelines.
• Go, Kubernetes, or cloud-native application development experience.
• Experience building large user interfaces that manage a lot of data. This includes skills in search, filtering, and tables. You should also have experience working with streaming or real-time data.
• Prior open-source / working-in-the-open experience, or time on a developer-facing platform team.
• Experience mentoring engineers or leading a small project team.
