Performance And Systems Engineer Jobs

About Sentry Software runs the world and the pace is faster than ever. Sentry helps developers fix errors and performance issues before users notice, so teams can spend less time firefighting and more time building. Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the role Agents are becoming the default way developers ship LLM-powered software, and they are miserable to debug. A single run fans out across model calls, tool calls, retries, handoffs between agents, and multi-turn conversations that only make sense as a whole. When one goes wrong, the developer usually has a log line and a shrug. Sentry's Agent Tracing turns that into something you can actually inspect: agent runs, tool calls, model interactions, token usage and cost, conversations you can replay message by message. As a Senior Software Engineer on the Telemetry Experience team, you'll own that product surface - Python/Django and Postgres on the backend, React and TypeScript on the frontend, sitting on top of Sentry's trace storage. You'll work with the SDK engineers who instrument the agent frameworks upstream and own everything customers touch downstream: the dashboards, the conversation views, the APIs, and the workflows that turn a confusing agent run into an obvious fix. In this role you will Own projects end to end. Take a problem from a rough customer complaint through scoping, design, implementation across the stack, rollout, and measurement. You'll write the design doc, cut the work into shippable pieces, and stay with it until the numbers move Build the views developers debug agents in. Multi-agent workflows, conversation replay, cost and token breakdowns, the moment where a run failed and why. Making a deeply nested, wildly variable trace legible is a genuinely hard interface problem Make the data underneath fast and queryable. Filtering and sorting millions of conversations, getting cost calculation ri

Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. Ready to build the future of mobile app monitoring? This is no ordinary engineering role. At Sentry, our Mobile SDK team creates the next generation of tools for developers worldwide, processing over a billion events every single day. We're looking for a talented Senior iOS SDK Engineer to join our team of experts. You'll dive deep into Apple's most advanced technology, from powerful new APIs and SwiftUI to Foundation Models. If you love using cutting-edge tech to solve complex challenges, you've found your team. What you will achieve in this role As the owner of our iOS SDK, you will guide its development from the core architecture to the final product experience. You'll pioneer exciting new features like Session Replay and next-generation performance monitoring, all while mastering Apple's latest innovations like modern concurrency and on-device AI. You will design robust, high-quality APIs built to handle massive scale, and you'll get to shape the overall vision for mobile at Sentry. Ultimately, you will be the go-to expert, helping our teams solve the most complex and interesting customer challenges. Why you will love this role We're looking for someone who is passionate about their craft and loves building elegant, intuitive tools that other developers are excited to use.

Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the role Sentry's SDKs instrument dozens of platforms and our ingest pipeline takes in billions of events every day. The Telemetry Experience team owns what happens next: the product surfaces and APIs where that telemetry turns into something a developer can actually debug with. As a Senior Software Engineer on Telemetry Experience, you'll own that experience across the sentry.io product - Python/Django and Postgres on the backend, React and TypeScript on the frontend. You'll work upstream with our SDK teams on what gets sent and with our ingest teams on how it arrives, then own the part customers actually touch: the APIs, the workflows, and the interfaces where it all lands. Your job is to make that feel native to every developer who uses it, whether they ship a backend service, a mobile app, or a game. In this role you will Own projects end to end. Take a problem from a rough customer complaint through scoping, design, implementation across the stack, rollout, and measurement. You'll write the design doc, cut the work into shippable pieces, and stay with it until the numbers move Work across the full stack of the Sentry monolith. React and TypeScript in the browser, Django and Postgres behind the API. Most projects here touch both, and the interesting decisions live at the seam Partner closely with SDK and ingest teams. Telemetry arrives exactly as the SDKs send it and as the pipeline shapes it. You'll shape those contracts together with the engineers who own them, rather than working around what shows up Collaborate daily with product managers, designers, and other product engineers.

Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the role Sentry is looking for an Engineering Manager to lead our Growth team (internally called "Value Discovery") and help expand our product-led business by helping customers discover and get the most out of our platform. At Sentry, we do growth with an explicit bias for customer value. Our experiments are rooted in strong product sense and empathy for developers, not conversion pressure. We never surprise developers with new charges or push features they don't need. In a binary tradeoff between doing good by the customer or good by the business, the customer always wins. You'll collaborate closely with several areas of the business including Product, BizOps, Data, Design, and GTM to identify the moments in a developer's workflow where Sentry can deliver more value, make that value easier to find, and support that your approach works with data. In this role you will You'll lead a team of engineers, set its priorities, and be accountable for the metrics it moves. This is a new role, and the roadmap is yours to define and execute in partnership with design and data teams. Lead work across Sentry's self-serve funnel — signup and onboarding, first-run activation moments in-product, trial and upgrade paths, and pricing and billing surfaces in partnership with the Billing team — largely in our Python/Django and TypeScript/React codebase Evolve our experimentation foundations, in close partnership with our Data team — flagging, instrumentation, and readouts are real but far from finished Run a fast, disciplined experimentation loop where hypotheses are argued before they're built Hold conversion and activation alongside ch

Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the role Ever wondered what it's actually like to intern at a company millions of developers rely on? Software Engineering Interns at Sentry write real code on real projects that ship to production. No fetch-the-coffee. Just you, a team that actually trusts you, and a codebase used by millions of developers every day, including the ones building the AI tools everyone's talking about. You'll land on either an SDK team or Ingest — and either way, you're in the critical path, not on the sidelines. SDKs are where past interns have shipped async support for our Python SDK and a faster AWS Lambda extension — real code running inside frameworks developers use every day. Ingest is the backbone: you'll get hands-on with the pipelines (including our open-source Relay and Symbolicator ) that process millions of events every minute. This is a 12+ week hybrid technical internship that treats you like a full-time Sentry engineer — not just "an intern." You'll be paired with a manager and a dedicated team mentor, get access to social events, and wrap up the program with a final presentation to the Sentry team. Don't just take our word for it — hear it from the people who lived it. Our intern blog is full of stories from past Sentaurs about the features they shipped and the teams they joined, and more than a few of them liked it enough to come back as full-time new grads. In this role you will Be matched with one of our SDKs , Product or Ingest teams, based on your interests and experience Design, develop, and ship a programming solution that drives real values to customers Receive meaningful feedback, coaching, and mentorship from yo

About the Role Sentry's blog, newsletter, and content programs need an owner — someone who can walk into ambiguity, decide what needs to exist, and just start making it happen. This is a self-starter role in the truest sense: no one is handing you a content calendar and asking you to fill it in, you're the one building the calendar. You should be quick with a draft and quicker to ship it — bias to action over polished process. You're technically savvy enough to keep up with a developer audience and write about our product credibly (or make an exec sound like they wrote it themselves). And you're proactive: you see the narrative before anyone asks you to go find it. You'll work collaboratively with Growth, Comms, PMM, and DevEx, with real ownership and editorial judgment to know what's worth writing and what isn't. In this role you will Co-lead blog strategy. Partner closely with Growth to run the editorial calendar, and scale the program by focusing on creating thought leadership, customer and employer brand content to create a robust narrative driven editorial program in collaboration with comms, devex and product marketing. Oversee the quality itself. Be the last line of defense on quality and prose — every post should read like it came from the same sharp, confident voice. Track the industry and get us into the conversation. Know what's trending in the developer and infrastructure world before it's obvious, and turn that into content that puts Sentry in the room. Collaborate with Comms and Marketing to push those narratives forward. Content partner for the exec team. Collaborate closely with core execs to support content

You'll partner closely with product and engineering teams to influence how features are designed and built from the start. You will work as a technical collaborator who helps make the secure path the obvious one. As Sentry expands our agentic product capabilities and development practices, you'll also find yourself at the frontier of a new set of security challenges. In this role, you will Support and help mature Sentry's security review program. From secure code review, to architecture review, and threat modeling. You'll help build the processes, tooling, and culture which make security a natural part of how we ship and operate. Contribute to mature vulnerability management practices.
