About Sentry

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.

The People function at Sentry brings together Talent Acquisition, People Operations, and Workplace Experience. Together, we exist to ensure Sentry attracts, retains, and activates exceptional talent—so people can do the best work of their careers while building a company we’re proud of.

Our mission is to help Sentry scale with intention: strengthening leadership capability, increasing accountability, and elevating performance—without defaulting to heavy, “big company” bureaucracy. We partner closely with leaders to build teams that are healthy, high-performing, and resilient as the business grows.

• Partner with leaders to identify and address performance gaps early, balancing high standards with fairness and empathy

• Manage complex employee relations matters, conducting thoughtful, objective investigations and recommending clear, appropriate outcomes that align with Sentry’s values and legal obligations

• Design and deliver practical, behavior-changing training for managers and leaders that translates directly into better team outcomes

• Use people data and insights to spot trends, surface risks and opportunities, and influence leadership decision-making

• Conduct attrition and sentiment analysis to identify drivers of turnover and advise leaders on interventions that increase retention and team effectiveness.

• Lead talent management efforts within assigned functions, including career pathing, skills development, and succession thinking

• Drive and contribute to cross-functional People initiatives that improve how Sentry operates and scales

• Help shape and implement People policies and programs that are clear, fair, and aligned with how we expect leaders to lead

You’ll Love this Role if You:

• Get real satisfaction from helping managers become better leaders

• Enjoy earning the trust of experienced leaders and influencing how teams are built and led

• Believe strong performance and strong culture go hand in hand

• Have a bias toward action and know when progress matters more than perfection
