Trunk is an a16z funded dev tools startup, redefining software development at scale. We aim to solve problems that developers hate by bringing the tools usually built in-house at the best engineering orgs to every development team. We've built 4 products so far and have plans for more:
* Code Quality: a universal linter/formatter, available as a CLI, VSCode extension, and CI check; * Merge Queue: a merge queue, to ensure that PRs are tested in order before they're merged; and * CI Analytics: detects, quarantines, and eliminates flaky tests from your code base. Prevents flakey tests from producing noise and blocking CI. *Flaky Tests: Detect and eliminate Flaky Tests. In 2022, we raised a $25M Series A led by Initialized Capital (Garry Tan) and a16z (Peter Levine) Our tech stack: * Frontend: Typescript, React, Redux, Next.js * Backend: Typescript, Node, AWS, CDK, k8s, gRPC * Observability: Prometheus, Grafana, Kiali, Jaeger * CLI: C++20, Bazel * VSCode Extension: Typescript * CI/CD: GitHub Actions * General: GitHub, Slack, Linear, Slite Unlimited PTO (and we all actually take PTO), competitive salary and equity packages! Please apply here: https://trunk.io/jobsMENTZ builds software for public transit agencies and authorities. One big part of our portfolio is an intermodal journey planning system - think Google/Apple Maps, but with a strong focus on public transit.
We're looking for a C++ backend dev to join the team working on the public transit router. We are currently in an exciting phase where we're working on the current and next generation of that public transit router simultaneously, so this position combines the possibility of having an immediate impact on a widely used product and working on something brand new.

Freeform is deploying metal 3D printing factories at global scale and setting a new frontier in manufacturing. With AI, GPUs, and FPGAs working in tandem, our system monitors and corrects every microsecond of the process, delivering a level of precision, speed, and quality that’s never been possible—until now. This isn’t just an improvement; it’s a leap forward in how complex metal parts are made, with the ability to revolutionize industries like aerospace, defense, automotive, energy, and beyond. We are backed by top VCs including NVIDIA’s NVentures, Founders Fund, and Threshold Ventures.
It’s a small, tight-knit team and you’d have the opportunity to own significant and impactful greenfield projects throughout the entire development lifecycle and much more. Our software team comes from the likes of Google, SpaceX, and Apple, and believe in taking a first principles approach to solving hard problems.

We recently announced $14.4 million in funding to make blockchains & digital assets useful for the world. Founded by Jump Crypto alumni and core contributors to the Solana protocol and the Firedancer client (https://github.com/firedancer-io/firedancer), we’re tackling fundamental scalability, performance, and usability challenges in distributed ledgers. Our runtime conforms to the RISC-V specification—moving away from domain-specific VMs, DSLs, and bespoke compiler toolchains that limit developer and institutional adoption. Components are developed in C for maximal control over performance and resource usage.
Interesting problems you’ll tackle:
- Building and testing high-performance subsystems in C (cryptographic routines, consensus primitives, networking protocols)
- Designing robust process isolation on modern CPU architectures and tile-based multi-core layouts
- Optimizing memory hierarchies, cache utilization, and low-level I/O for commodity servers
You:
- 5+ years of systems programming in C/C++, Rust, or similar
- Deep expertise in CPU microarchitecture, memory subsystems, and low-level performance tuning
- Strong understanding of distributed systems design and consensus protocols
- Experience with high-performance networking and protocol design in real-time environments

I'm a team lead engineer at Annapurna Labs, the small company-within-a-company that designs AWS custom silicon. My organization designs and runs the Trainium and Inferentia machine learning (ML) accelerators. Our team is hiring engineers to help build the on-chip firmware stack for new and existing chips. This firmware is the lowest layer of the Neuron software stack; you can think of it as implementing a silicon-accelerated virtual machine that the Neuron compiler targets.
This is a bare metal, system software-oriented role (think C/C++); no specific ML experience is needed, but if you have experience writing GPU/CUDA kernels or microcode for other systems, we can definitely put your experience to work. If you're interested in machine learning, you'll be adjacent to people who have tons of experience with high performance compute, chip design, and ML algorithms.
We offer relocation to Austin or Cupertino; the team is split evenly between the two sites.
Ping me if you're wanting to chat about the team or the role: ghilliar -at- amazon.com. I'm an embedded systems engineer and I don't bite :)
