xdof | Robotics Engineers, Infra Engineers, Product Engineers, GTM | SF Bay preferred, NYC & Remote possible for non-robotics roles

At xdof, we're at an inflection point. Frontier labs are racing to build general-purpose robots, and high-quality training data is the bottleneck. We're building the foundation behind the foundation models – the data collection systems, operational capability, exabyte-scale data warehouse, and software toolchain – to help our partners drive the field forward.

Founded by UC Berkeley Robotics PhDs and MechEs, this is a team that executes across software, hardware, and operations faster than I can believe sometimes. This speed and ability to deliver has led to partnerships with many of the top players in the space.

We are not quite yet out of stealth, so not able to share more details here, but are so understaffed relative to demand that I'd like to start semi-public hiring ASAP.

Cybersecurity/AI seed startup | Founding AI Engineer | Bay Area | Full-time

We're seed-staged, 3 people, building an AI for cybersecurity, looking for a founding AI engineer who wants to learn/apply SOTA techniques for AI. Ideal background is experience building production agentic AI systems (by this I mean something like Simon's definition: https://simonwillison.net/2025/Sep/18/agents/ definition) who also likes to think about WHAT to build and not just how.

We are a Golang/Python shop (although I'm not sure that matters so much any more).

CV: Available Upon Request

Email: poetic.artifice@gmail.com

I am a seasoned (>15 years experience) full-stack staff-level software engineer specializing in the backend, systems architecture, AI, platform engineering, internal tools, prototyping, and data engineering. In addition to strong programming and architectural skills, I'm a force multiplier for any team in either role through the three T's -- teaching, talking, and tooling. I also hold a US patent in the AI space.

In the past, I've taught a number of scientists and students to code in python; I've led and managed a number of high-impact engineering teams of up to 12; and pioneered a number of no- and low-code solutions for stream processing, data model and query generation, form building, workflow systems, and front-end construction for a variety of industries, including those with strong regulatory requirements and complex business rules such as healthcare and fintech. >10% of all medicare applications and millions of individuals currently flow through pioneering no-code systems I conceived and built and have ran in production for over a decade.

More recently, I've built a no-code automated form-filler; a no-code web scraper (and an AI for generating such scrapers from a spec and 1-3 example urls from a page); and a workflow engine for coordinating LLMs and other generative AI processes, and on top of this a platform for both minimizing hallucinations and working with documents that are far too large for existing context window inputs or outputs using a novel, patented process that I invented; and applied these tools to various contracted projects requiring analysis and and cross-checking of information and other forms of integrity across textual and video/audio corpus data in a variety of domains (fiction and non-fiction).

I am also an improvisational pianist, published poet, and I've created novel algorithms and tools for studying and composing both music and poetry, which I have given a talk on at a recent functional programming conference.

I have extensive experience working for and running startups, software consulting shops, with some mid-sized company engineering experience as well; these give me a unique insight into speaking with customers and internal stake-holders, translating between engineering and other departments, gathering requirements, aligning stake-holders across departments on a vision and attainable timeline, and architecting/building/taking ownership over significant internal and customer-facing areas of responsibility.

If any of the above seems like a match for you and your organization or project, don't hesitate to reach out. I am available for both full-time positions and short- and long-term contracts.

Unto Labs | San Francisco, CA | ONSITE (Hybrid OK), REMOTE (US) | Full-Time Unto Labs is developing the Thru Layer-1 blockchain (https://thru.org) 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.

GrackerAI | Backend Engineer | REMOTE | https://gracker.ai

We are building the infrastructure for the post-SEO era.

Kinelo | kinelo.com | Full-Stack Engineer (AI + Backend) | San Francisco | Onsite

Kinelo manages the new type of hybrid team that will emerge in the future: humans+AI working shoulder-to-“shoulder”.

Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike.

Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today).

We’re looking for high ownership individuals to join our small team and shape its direction. We also just opened a new SF office and new hires will have the ability to help shape company culture, engineering practices, architecture, and roadmap.

We’re well-funded (just raised another round), founded by a serial founder, anti-bureaucratic, and highly technical.

We’re looking for:

- Those who want to go 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product

- ~8 years professional experience, including the pre-LLM days with strong CS fundamentals

- A balance of wisdom from experience and optimism about the future

- Strong TypeScript and Postgres (or other RDBMS) experience at scale and with high reliability (SaaS apps, APIs, etc)

- Experience with a variety of technologies, including containerization, distributed systems, and at least one strongly typed programming language (Go, C++, Java, etc)

- Ideally experience with ML and AI systems (though expertise in ML, data science, etc is not needed for this role)

We can’t sponsor visas but relocation assistance to SF is possible.

Please apply here: https://job-boards.greenhouse.io/kinelo/jobs/4088659009 and also email jobs@kinelo.com, mentioning this post.
