ABOUT BASETEN Baseten powers mission-critical inference for the world's most dynamic AI companies, like Cursor, Notion, OpenEvidence, Abridge, Clay, Gamma and Writer. By uniting applied AI research, flexible infrastructure, and seamless developer tooling, we enable companies operating at the frontier of AI to bring cutting-edge models into production. We're growing quickly and recently raised our $1.5B Series F , led by Altimeter Capital, Conviction Partners, and Spark Capital. Join us and help build the platform engineers turn to to ship AI products. THE ROLE Baseten is building its own GPU infrastructure for large-scale inference. As we move into large scale, high-density NVIDIA systems, the hardest failures are intermittent, cross-layer, and difficult to prove: RoCE congestion, InfiniBand stalls, ECN/DCQCN mis-tuning, bad optics, RNIC issues, host kernel stalls, GPU driver problems, and workload symptoms that look like network problems, but are not. We are hiring a Lead Software Engineer to build a first-class observability and root-cause analysis system for GPU fabrics. This is a hard distributed systems problem, not a dashboarding problem. The system will collect high-volume signals from switches, hosts, active probes, and inference services; reduce and correlate them in real time; understand topology and service ownership; and produce actionable diagnosis while an incident is still unfolding. This role sits at the boundary between networking and inference software. RDMA data paths, GPUDirect transfers, prefill/decode disaggregation, KV cache movement, request routing, and workload backpressure can all create fabric symptoms or hide real fabric failures. The goal is to tell an operator, quickly and with evidence, whether an incident is caused by the fabric, host, NIC, GPU, RDMA path, scheduler, or serving layer — and what to do next. EXAMPLE INITIATIVES Real-time telemetry engine — Build the ingestion, reduction, storage, and query path for high-cardinality fab

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 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

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. Be Sentry's face in the startup ecosystem. Show up at demo days, founder events, and SF tech week. Build relationships with the people building the next generation of companies. Not because it's a line item, but because you'
