Bad software is everywhere, and we’re tired of it. Sentry is on a mission to help developers write better software faster so we can get back to enjoying technology.

With more than $217 million in funding and 100,000+ organizations that believe we’re on to something, we're building performance and error monitoring tools that help companies like Disney, Microsoft, and Atlassian spend less time fixing bugs and more time building products.

Sentry embraces a hybrid work model across our global hubs, with Mondays, Tuesdays, and Thursdays set as in‑office anchor days to encourage meaningful collaboration. If you like to selfishly build things that make your digital life better, come help us build the next generation of software monitoring tools.

About The Role

The security team is responsible for and committed to securing all things Sentry. From our customers, to our code, and everything in between, the security team is involved in all aspects of the business in pursuit of that goal.

Sentry is looking for a Senior Security Engineer to join our growing security team, working across application and platform security domains to drive security solutions for hardening our evolving cloud‑based application and Kubernetes platform. You will partner with engineering to mature Sentry’s holistic cloud platform security posture through effective security architecture, project‑specific threat modeling, and occasional coding.

In this role, you will

• Lead highly impactful initiatives to solve critical security challenges, from idea formulation to design and implementation
• Work on cross‑company objectives to influence and achieve security objectives
• Research and evaluate new technologies to enhance the company's security posture with an eye towards scalability
• Identify potential threats and vulnerabilities in our systems and data, as well as help develop and implement solutions to safeguard them
• Enable cross‑functional teams to implement security solutions aligned with Secure‑by‑Design concepts and standards

You’ll thrive in this role if you

• Want to be an early member of an agile and engineering‑focused security team
• Enjoy collaborating with passionate security, application, platform, and infrastructure engineers who are eager for ideas and action
• Are passionate about creating and collaborating on technical designs and plans
• Are motivated to continue developing and learning new skills

Qualifications

• 6+ years of industry experience designing, building, and supporting large‑scale distributed systems in production
• Strong fundamentals in computer science skills.
• Experience in securing container‑based environments in cloud platforms (e.g., AWS, Azure, GCP) and their SDKs/APIs.
• Degree in Computer Science or related field.
• Experienced and comfortable programming in at least one language, with a strong preference for Python, Go, or Rust.
• Applied knowledge of cryptography, PKI, TLS, and practical implementations.
• An up‑to‑date understanding of the threat landscape as it pertains to SaaS companies.
• Strong communication skills.
