Software Engineer, Cloud Security Posture Management

About Oneleet:

Oneleet is on a mission to revolutionize the industry. We make cybersecurity easy, effective, and painless through a comprehensive platform that helps companies build, manage, and monitor their cybersecurity programs.

Backed by Y Combinator (S22) and top-tier VCs, our founding team brings over a decade of penetration testing and cybersecurity experience. Join our remote-first crew of opinionated rebels building a category-defining company to fix a broken, fragmented industry.

We value passionate self-starters with a growth mindset and a bias for action and personal accountability. If you love solving hard problems, thrive in ambiguity, and want to make a real impact, you’ll fit right in.

We’re especially drawn to:

• Rebels with a cause — frustrated with the status quo and eager to disrupt it.
• Opinionated (but not obstinate) builders — decisive yet collaborative, who help us move fast.
• Clear communicators — who own their ideas and follow through.

Our mission is simple: make effective cybersecurity painless. We believe cybersecurity should empower, not burden. This belief unites our team and drives every decision we make.

If you’re ready to challenge the status quo and help shape the future of cybersecurity, we’d love to meet you.

As a security platform for startups, our CSPM product monitors cloud environments across AWS, GCP, and Azure to ensure customers are configured securely. For example, we detect exposed storage buckets, verify encryption standards, identify overly permissive IAM policies, and track compliance with security frameworks.

You will extend and improve Oneleet's CSPM capabilities, working on everything from cloud provider integrations to security policy development. You’ll contribute to the design and implementation of cloud security monitoring features, build detection rules for new attack vectors, and ensure our CSPM product scales reliably as customers' cloud footprints grow. You’ll work with various security solutions including vulnerability assessments, compliance scanning, configuration monitoring, and risk scoring systems.

As a seed stage startup, you'll have the opportunity to collaborate with the founding team to understand business/customer needs and contribute to building the core technology that powers the Oneleet platform.
