About the Job:

We’re looking for a Principal Engineer to drive the vision and execution of our Core Engineering teams and to provide leadership across our entire engineering organization. Core Engineering is responsible for LaunchDarkly’s platform layer spanning core shared services (e.g. our internal orchestration engine) and our service platform layer (e.g. Kubernetes). In this role, you would have a wide impact on shaping the current state and north star for engineering architecture and practice at LaunchDarkly. Areas of focus would range from deployments, authentication, core services across products, data models and stores, AI engineering and beyond. You would work cross-functionally at the intersection of business priorities, customer scale, and technical requirements and constraints.

This is a unique opportunity to have an immediate and ongoing organization-wide impact.

Responsibilities:

  • Along with other senior engineering leaders, clearly articulate a vision for the LaunchDarkly service architecture and an incremental path to get there.

  • Define and maintain a prioritized platform roadmap that balances capability delivery, operational health, and bug fixing. In order to do so effectively, you must deeply understand the opportunities and pain points within LaunchDarkly’s engineering team.

  • Be the connective tissue between engineering teams across multiple products, domains, and technologies.

  • Coach, mentor, and grow engineering leaders across the organization.

  • Guide architectural decisions and contribute to code reviews and technical designs.

  • Foster a culture of collaboration, ownership, continuous learning, and inclusivity.

  • Stay current with technologies and software development trends, and drive their adoption where appropriate.

  • As part of our you-build-it-you-run-it culture, all engineers may be responsible of support applications in production, including on-call.

Qualifications:

  • 5+ years operating at a Staff+ level focused on building and operating production-grade web services.

  • Experience building and operating data stores such as CockroachDB or Aurora PostgreSQL.

  • Experience building serverless architecture as part of a larger service landscape.

  • Experience building with different authentication and transport protocols such as OAuth and REST.

  • Experience operating at the intersection of technical requirements and constraints, business priorities, and customer scale, and understanding how they all interplay.

  • The ability to track and drive metrics, and the wisdom to understand what they can and can't tell you.

  • Excellent communication skills with both technical and non-technical stakeholders.

  • A thoughtful, empathetic approach to leadership and collaboration.

About LaunchDarkly:

Modern software delivery was supposed to be the foundation for a thriving digital business but reality has proven otherwise. Slow, inefficient development cycles, costly outages, and fragmented customer experiences are preventing developers from building their best software. The LaunchDarkly platform helps developers innovate on new features faster while protecting them with a safety valve to instantly rewind when things go wrong. Developers can target product experiences to any customer segment and maximize the business impact of every feature. And by gradually rolling out new application components, they escape nightmare "big-bang" technology migrations.

The LaunchDarkly platform was built to guide engineers to the next frontier of DevOps by:

  • Improving the velocity and stability of software releases, without the fear of end customer outages
  • Delivering targeted experiences by easily personalizing features to customer cohorts
  • Maximizing the business impact of every feature through the ability to experiment and optimize
  • Coordinating the release and optimization of software to provide consistent experiences across mobile platforms and device types
  • Improving the effectiveness and productivity of engineering teams, by providing insights into engineering cadence and stability

We are an equal opportunity employer and value diversity at our company.
