Shepherd | ONSITE | San Francisco, CA At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered. The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that. We just recently announced our $42M Series B! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building. (Hear from our CEO here: https://www.shepherdinsurance.com/blog/behind-our-42m-series... ) (Hear from our CTO here: https://www.shepherdinsurance.com/blog/the-road-to-autonomou... ) This year, we’re growing our engineering team from 25 to 40.

Loophole Labs | Senior Systems Engineer | REMOTE (Americas & Europe) | $150k–195k USD + equity | Go, Zig, Rust, C, eBPF, CRIU, Kubernetes We make Architect: a Kubernetes runtime that hibernates idle pods in place and wakes them in 50ms with TCP connections intact. Five engineers. You'd be the 6th. If tracing an x86 instruction in the morning and hunting a control-plane race in the afternoon both sound fun, and you insist on measuring rather than guessing, this is the job. Customers run Architect for workloads where cold starts hurt: real-time voice & video AI agents, long-warming JVM apps, stateful data services that can't be rescheduled cheaply. 1.0 shipped Q1 2026; you'd join mid-way through 2.0. Seed-stage, VC-funded, a few years of runway. Fully distributed across the Americas and Europe. What you'd work on: - Hibernation surface: containerd shims and CRUISE, our Zig-native CRIU replacement. - Control plane: per-node DaemonSet streaming checkpoints; admission controller resizing hibernated pods in place. - Networking and migration: eBPF/XDP at line rate; cross-node live migration to production; cross-cloud next. You're a senior generalist. Years across the stack: assembly to frontends, hardware-near, comfortable in x86. Tests ship with the code, decisions get worked out in writing, and you measure rather than guess. Strong in Go; willing to use Zig, Rust, or C. Bonus: eBPF/XDP, CRIU, Linux kernel internals, containerd, gVisor, live migration, or public writing in kernel/container/eBPF land. Strong systems depth and the willingness to pick up the rest is enough on its own. Apply: https://loopholelabs.io/careers - we respond within the week (typically a few days).

Burnin (London or NYC) | Founding Research Scientist + Founding Engineering Lead | Hybrid (Some on-site) | Full-time We are building the trust stack for AI code generation, targeted at high-stakes computing where wrong numbers cost real money: a statically typed functional language designed for coding models, a compiler whose guarantees double as audit-grade trust infrastructure, and a coding model fine-tuned on the language with compiler fitness as the training signal. Language and model are co-designed. Small team out of PyTorch, FAIR, and Meta. Strong institutional VC support from our pre-seed; active investor interest heading into seed. Founding Research Scientist: own the agenda across the language and the model. Type system design, compiler analyses that produce useful fitness gradients, and fine-tuning open-weight coding models on a language with no pretraining footprint. Publish in PL and ML venues. Strongest fits cross between machine learning, programming languages, and formal methods. PhD preferred, equivalent output equally fine. Stack is Rust, Lean 4, Python. Founding Engineering Lead: own engineering across compiler internals, language runtime, GPU backends, notebook and library tooling, and the AI infrastructure around training, evaluation, model release, and likely public inference. We already support x86 and ARM, CUDA and AMD, macOS and Linux, and the matrix grows. Real feel for statically typed functional programming expected; the kind of engineer who picks up Lean or Haskell on a weekend because they wanted to. Have led engineering before, formally or not. Stack is mostly Rust with Python where it earns its place, primarily on AWS. Both roles: comfortable with early-stage ambiguity, define your own roadmap, defend it with evidence.

You: - Fluent in Typescript, Python, and framework/tooling agnostic (Currently using things like NextJS, Supabase, Cesium) - Eager to learn about mining domain knowledge around the software. - Ownership of the codebase, and the systems that support the software (project management, CI/CD, monitoring, etc.) - Open to doing a yearly month abroad with Neil and I.
