Govra | Senior/Staff Full Stack Engineer | Hybrid (SF Bay Area) | Full-time

Govra builds the operating system modern governments run on. We turn dense statutes and tangled rules into executable workflows, embedding intelligence directly into the work so agencies make faster, more accurate and more consistent decisions at scale. We're starting with tax, one of the highest volumes in government, where better decisions mean more revenue, better public services and improved trust between citizens and the state. The result: government that works at the speed of the people it serves.

We are seeking a Senior or Staff Software Engineer to help build and scale Govra’s intelligent operating system for governments. You will work closely with the founders, customers and product design teams to ship vital real systems in a fast-moving, high-impact environment. This role is ideal for someone who can go deep technically, think from first principles about product and UX, and move quickly from customer workflows to production code.

Natural | SWE (Product, Data, Design, Infra, Payments), Product Designer, GTM, more | San Francisco, CA (Onsite)

We're building payment rails for AI agents; fully-owned rails across traditional banking and stablecoins, and the full set of funds flows that AI agents need to transact in the real world with businesses, consumers, and other agents (wallets, pay, request, credit, billing, and more).

We've raised from some of the most well-known operators in fintech & payments to shape how agents interact with the economy, from scratch.

I've decided to no longer post here after the incredible amount of spam I started receiving, both in terms of direct email submissions as well as unqualified and outright fraudulent applications to my application tracking system.

By fraudulent I mean: fake resumes, names stolen from real developers who work at well-known companies but either don't have a linkedin/portfolio or do have a linkedin/portfolio without a profile picture. So easily impersonated by a scammer.

It is a real shame, but this thread is now being scraped by plenty of other sites and bad actors.

Inbound hiring for remote teams is basically cooked at this point, signal is completely hidden in the noise. Curious if anyone else has had this experience or if it's just me?

Speckle | Head of Delivery | London (hybrid; UK-based) | Full-time | £120–140k base + variable (OTE ~£160k) + meaningful equity

Speckle is the open-source platform that makes 3D/AEC design data accessible, trustworthy, and queryable across every tool in the stack - Revit, Rhino, IFC, ACC and more. We've just launched Speckle Intelligence: ask your project models anything, trust the answer, and generate client-ready deliverables in minutes. 23 people, open-source core, enterprise tier on top, post-Series A. Repo: github.com/specklesystems

We're hiring our first Head of Delivery to own the enterprise post-sale motion: turning pilots with general contractors, owners, and large service providers into expanded production deployments. Forward-deployed role (think Palantir FDE, not SaaS customer success) - you sit inside the customer's real decision problem, make "trust the answer, take the action" true on their actual data, and feed what you learn back into product. We measure impact and not closed ticket counts.

Good fit if you've delivered technical/data products into heavy industry (AEC, construction tech, infra, or similar) and can read an enterprise's problem without a spec. AEC background a strong plus, not required. Comfortable with messy data and ambiguous orgs.

Annex Risk | Full-stack + Backend Engineer | Bay Area, Austin | Full-time

The cost of homeowners insurance, especially in natural catastrophe prone areas, has skyrocketed in recent years. Annex is solving this problem with better digital infrastructure for executing the transaction. Our platform enables insurance agents to quote and bind policies within 90 seconds vs. the current multi-day phone/email/fax-based transaction that is the status quo.

We grew 4x in 2025 and anticipate similar growth in 2026. We've done the above after deploying <$1.5m in funding. We have significant and growing momentum on both the insurance distribution and insurance capital sides of our business; our challenge now is scaling our engineering team to support that progress.

We're in that exciting early stage, where someone can contribute foundational new pieces to core parts of our platform.

Railway | Infra Eng-Storage, Infra Eng-Observability, Product Design, Infra Eng-General, Product Eng (full-stack) | REMOTE (Worldwide) | https://railway.com/careers

Do you feel scared and alone when opening the AWS console? Do you wish you could just tell Claude to manage your infra, and it would just work? Do you dream of a future where software is abundant and developers and normies alike are free to build their wildest dreams?

We're Railway, and we think infrastructure can be better. We're working at the forefront distributed systems engineering, interface design, and agentic computing to bring about the infrastructure platform we've always wanted. So far we've built out a platform loved by 3M+ users and we're just getting started.

Fair warning!

Lantern | Software Engineers (Python, Full-Stack) | NYC (Onsite) | Full-time | withlantern.com

Lantern is building AI-powered revenue intelligence—autonomous agents that turn cold outreach into warm conversations.

Trax | Analytics Engineer | REMOTE (Philippines, Costa Rica, US) | Full-time Contract

We're hiring an Analytics Engineer to help power our future. This is a really greenfield project where we need to define the data models that fuel all reporting, analytics, and ML/AI going forward. We do 'freight audit' - we save our clients money by making sure all their logistics spend is correct and as agreed.

At Trax, our data infrastructure is in the middle of a real transformation. We're building the data foundation that will power our next wave of AI features, and we need someone who can own that work end-to-end. This isn't a "run queries and make charts" role.

You'll be:

- Designing and maintaining data marts in dbt + Snowflake

- Building customer-facing dashboards that integrate into our platform

- Bridging the gap between engineering, business ops, and client teams

- Running ad-hoc analyses that drive real decisions

- Shaping how our data platform evolves alongside our AI/ML capabilities

What matters most to us:

- Deep data modeling knowledge (domain logic, not just syntax)

- Advanced SQL; dbt and Snowflake experience is a big bonus

- Strong communicator who translates between technical and non-technical worlds

- A learning mindset; genuinely non-negotiable for us

We're a small, close team. You won't disappear into a large org. You'll work directly with leadership, partner with Solutions and Sales, and have a real voice in how we build. If you thrive on ownership, are energized by complexity, and want to see the direct impact of your work, let's talk! My email and linkedIn are in my profile.

Kinelo | kinelo.com | San Francisco | Onsite (with a bit of flexibility)

Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.

We're hiring for two roles right now:

- Product Engineer / Senior Software Engineer (https://job-boards.greenhouse.io/kinelo/jobs/4205846009) -- do you have the software engineering wisdom not yet encoded in an LLM? and do you have product sense and the willingness and desire to think several steps ahead in the market?

- Founding GTM Lead (https://job-boards.greenhouse.io/kinelo/jobs/4215784009) -- there's no playbook for go-to-market in the category we're creating + the landscape is changing daily. Come architect a strategy and then move mountains to execute on it and help us grow insanely fast.

Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).

Please email us at jobs@kinelo.com.

If you want to stand out: - For the product engineer role, tell us how you think the job of a software engineer is changing. - For the GTM role, tell us about a time you got massive results with limited resources, all through your ingenuity, creativity, and hard work.
