SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Ashby | YC 19 | REMOTE | Hiring Product Engineers | Sr: $153k-$220k, Staff: $190k-$275k

Ashby is the all-in-one recruiting platform powering hiring at the world’s most innovative companies. If you cmd+f “Ashby” you’ll see that we’re powering many of job postings in this thread!

* Grew our engineering team from 30 -> 60 last year with plans to double again in 2026.

* 80%+ of our engineering team is made up of Senior-Staff+ level Product Engineers. We give an unusual amount of ownership to our engineers to build features end-to-end. Many of our most loved features were build entirely by a single engineer!

* 100% remote asynchronous culture with an even distribution of engineers across North America and Europe

* Full transparency on engineering levels + comp: https://www.ashbyhq.com/blog/engineering/leveling-and-compen...

Stack: TypeScript (frontend & backend), React, GraphQL API, Node.js, Postgres, Redis.

Full list of open roles: https://www.ashbyhq.com/careers

Stackable | Product Engineer - Web & UI | Remote (Germany/UK) | ~20 people | Full or part-time

We build an open source data platform on Kubernetes. The product (Stackable Data Platform - SDP) bundles 12+ open source data tools (Trino, Apache Kafka, Apache Airflow, Apache Superset, etc.) and makes them work together. Right now everything is Infrastructure-as-Code only. We need someone to build a UI layer on top.

No mockups, no Figma, no product roadmap waiting for you I'm afraid, just a bunch of ideas :) We're all backend people and need someone to own this end to end. Play around with our product stack, figure out what customers actually need, build it.

Stack (because we got started without you...): Svelte/SvelteKit, TypeScript, TailwindCSS. SDP itself is Rust, Java, Python on K8s. Three releases a year. Not SaaS. Quality matters.

100% remote, Germany (UK possible) only, no other countries, sorry. No Scrum, minimal meetings. Interview process is usually just two conversations. The position isn't on our homepage yet as I'm on vacation. Send a mail to recruiting@stackable.tech and I'll get back to you next week. Please mention HN in your mail. My personal mail is also in my HN profile. I'm the Co-founder and CTO.

Kinelo | kinelo.com | Product Engineering (Backend+AI focus) | San Francisco | Onsite (with flexibility)

We are hiring two Product Engineers to join us in our newly opened office in SF. We're small and early and you'll help shape team culture.

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.

Our #1 hiring criteria for this position is immense software wisdom, the kind not yet encoded in the weights of an LLM. We are not looking for artisans to meticulously craft single lines of code. We're looking for software engineers excited to use the leverage that AI offers for code production to permit focus on higher order technical architecture, product requirements, and user needs.

We're looking for enough experience that indicates accumulated wisdom in shipping and maintaining reliable, scalable software, solid CS fundamentals, experience taking products from 0 to 1, and versatility.

Our current tech stack includes TypeScript, a managed container service, Postgres, and Redis. But we are adaptive and you should be too. We highly value software engineering and computer science fundamentals and experience with other languages like Go, C++, Python is valued.

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, tell us how you think the job of a software engineer is changing. There's also a full JD here: https://job-boards.greenhouse.io/kinelo/jobs/4205846009

Luminate | Software Engineer | Onsite Los Angeles, CA | Full Time

Luminate is the entertainment industry’s preeminent data and insights partner, serving as the single source of truth for record labels, film studios, talent agencies, and every part of the music and entertainment ecosystem.

The team's stack is Java w/ Spring, React w/ Typescript, and SQL w/postgres, and snowflake. We use playwright for e2e testing and deploy our infra on AWS.

The team is relatively new (around 3 years old) but is working on an older codebase with plenty of tech debt. Luckily we actually _do_ get time to address our tech debt and take the time to leave our code better than we found it, so it's getting better all the time.

We have an oncall rotation but getting paged is pretty rare.

Apply here: https://luminatedata.com/careers/?gh_jid=4677478005

Please mention Hacker News in your cover letter.
