Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the role The Developer Experience team is growing in San Francisco! This is a hybrid role out of our main headquarters and must be based there. We’re looking for a hands-on builder with strong opinions on great developer docs. Are you someone who loves tinkering with the newest features in your favorite products? Do you enjoy taking the next random JavaScript framework for a spin and figuring out how to make them tick? Does it especially irk you when the code snippets are wrong, or the only docs for a feature are on X? Developer Experience at Sentry lives in the intersection of shipping really cool products and getting developers set up to use them. If you’re someone who is confident in partnering with Product and Engineering to test and ship the latest features, not afraid to jump in and go hands-on to solve problems for our biggest customers, and a good eye for what good docs looks like - this is a dream role. Developer Experience at Sentry is a team of builders who are constantly looking for ways to make it easier for every developer to use Sentry. We engage with the challenges facing technical communities, to support developers, gather feedback, and help our product and engineering teams ship new capabilities. An engineer in this role should be confident to “come with an answer," propose the product solutions, identify the content and/or execution plans and people to partner with, and go execute. In this role you will Attend and even host events and meetups in the developer community Have a point of view and aren’t shy about expressing it. You get your energy from both knowing the latest trends and having a POV on

Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the role AI and machine learning are reshaping how developers debug, monitor, and ship software, and Sentry is uniquely positioned to lead that shift. We sit on a novel and massive dataset of real production errors, spans, and logs from tens of thousands of engineering organizations — the kind of signal that makes ML genuinely useful, whether it's a clustering model that groups related issues, a ranking system that surfaces the right alert at the right time, or an agent that proposes a fix. We're looking for an Engineering Manager to lead and grow our Machine Learning Engineering team. This team owns the full spectrum of ML at Sentry: classical techniques like clustering, ranking, anomaly detection, and embeddings that quietly power core product surfaces today, alongside the LLM-based and agentic systems shaping where the product is headed. You'll partner closely with product, design, and engineering leaders to decide where ML belongs in our products, what kind of ML actually fits the problem, and how we translate that work into experiences millions of developers rely on every day. In this role you will Set technical direction across the team's full ML surface area — from classical models for clustering, ranking, and anomaly detection to LLM-based and agentic systems — and make sharp calls about which approach fits each problem Define how the team evaluates and monitors ML systems in production, from offline metrics to online experimentation to model and agent observability Stay hands-on enough to review code and model designs, contribute to architecture discussions, and unblock engineers on complex ML problems Define

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 already has a startup program: credits, partner deals with YC and a16z, a landing page with a terminal theme that developers actually think is cool. What we don't have is someone whose full-time job is making this program a real growth engine. That's this role. You'll own startup marketing end-to-end: the partner ecosystem, the community presence, the acquisition programs, the brand in rooms full of founders and early engineers. You'll take what exists today and turn it into something that makes Sentry the default monitoring choice for every new company shipping code. This role reports to the Head of Enterprise Marketing (yes, we get how this can be confusing, but she’s pretty cool) and works across Growth, Product Marketing, and DevEx. You'll have real autonomy to shape the strategy and build programs from scratch – but you'll also need to execute quickly, (kind of – we can explain more) measure what works, and kill what doesn't. In this role you will Build and scale startup partnerships. Expand relationships with accelerators, incubators, VC platforms, and startup deal aggregators. Make Sentry's credits program a no-brainer inclusion in every startup perks stack. Own the startup acquisition funnel. Design programs that move early-stage companies from free plan → credits program → paid customers → expansion. Instrument everything so we know where the pipeline is and where it leaks.

Getting it to the right customers, at the right time, in the right way, is where the real complexity lives. We're looking for a Senior Technical Program Manager to own the end of the EPD pipeline: the moment a feature is built to the moment it's successfully in customers' hands. This person will define what "good" looks like for product launches at Sentry, building the frameworks, playbooks, and operating rhythms that make every release more intentional, more coordinated, and more confident than the last. The foundation is there. Features ship. But the connective tissue between Engineering, Product, Legal, Marketing, go-to-market (GTM), and Sales needs someone who can see the whole system, diagnose what's broken, and build something durable. That's this role. If you're energized by ambiguity, love designing operating models, and want real ownership over a function that touches every team in the company, this is a rare opportunity to define the craft at a company that takes software quality seriously. What You'll Do Define the Launch Standard: Establish what a great product launch looks like at Sentry: the gates, the playbooks, the decision rights, and the rituals. You're not inheriting a fixed process; you're authoring it. Own Feature Flag & Cohort Strategy: Bring intentionality to how Sentry uses early access programs, beta cohorts, and staged rollouts.

You'll report to the Head of Technical Program Management and work closely with the VP of Platform Engineering, their staff, and partner teams across Engineering, Product, and Design (EPD). This is a high-visibility role with real influence. You'll work directly with the CTO and senior leaders, shape how the Platform org operates, and help Sentry scale through one of its most important chapters. In this role, you will: Drive strategic execution. Partner with the VP of Platform Engineering and senior EPD leaders to translate priorities into clear, measurable plans. Own sequencing, milestones, and key decisions, and make sure leadership always has reliable visibility into progress and tradeoffs. Build data-driven delivery health.
