Ready to join a mission that matters? The future of cybersecurity starts with you.

The Lightning Team is seeking a Senior Software Developer (equivalent to a Staff or Sr Staff role in other companies). This product is responsible for the cloud services that provide security information to the endpoint agent in near-real-time. The services that store this information aren’t always near-real-time themselves, so we use a variety of strategies for caching, back pressure, and partial responses.

You’ll be building high-quality systems that scale cleanly and reliably, primarily in Go (and also some Python). We’re involved across the entire product line and you’ll work closely with other groups across the company. This role is hybrid, requiring 2-3 days per week on-site in one of the posted locations. It is a welcoming and flexible team that prizes collaboration over competition, providing opportunities to learn new skills, mentor developers at all levels, and contribute to the direction of both the team and its products.

It is a high trust environment where team members manage their own time, take time off as needed, and are rewarded with competitive salaries and equity.
