Trinsic | Software Engineer | REMOTE (North America) | Full‑time
We’re building the first Identity Acceptance Network—the “Visa for ID.” Humanity is editing genes, starting space tourism and working on artificial intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards . We’re bringing identity into this new age, where trust is essential and becoming more so every day with AI. We enable accepting digital IDs that users already have (mDLs, BankIDs, reusable IDs) and verify users ~10x faster across 40+ networks covering 500M+ people.

- Strong backend experience; generalist who enjoys moving up/down the stack.
- You care deeply about user privacy and data security.
Stack & ways of working
- .NET (C#) backend, React + TypeScript frontend, Azure, GitHub CI/CD.

Goblins | https://goblinsapp.com | Founding Engineer #3 | Williamsburg, New York | ONSITE | $100-200k (+ generous equity)
In education, we have always traded off scale and quality. In a 30-student math class, half of kids are ready to accelerate while half are still working on their foundational skills, but teachers cannot be in 30 places at once, giving each student one-on-one support.
Until now. Imagine 30 teachers in every classroom—that's how Goblins feels. Students draw math on any device, and our AI figures out the "why" behind their confusion, giving instant feedback and building conceptual foundations. (Try it out here! https://app.goblinsapp.com/onboard)
Goblins launched to school districts in the spring of 2025. Since then we've built a waitlist of thousands of teachers and sold Goblins to districts across the US (we'll hit 100k+ paid students this year!). We are in the unique position of having a product that is both highly differentiated and demanded :)
Technical problems that we find interesting:
→ Building knowledge graphs that adapt to student performance in real-time, routing them to the optimal next problem they should solve to maximize learning and engagement.
→ Extending our handwriting recognition from digital canvas to real paper through Chromebook cameras (think real-time OCR on math equations through low-quality webcams with poor lighting)
→ Creating interactive mathematical lessons (think 3blue1brown, but conversational) that remediate student misconceptions.
You'll be joining founding team members Sawyer (CEO, former Head of Design at X1 [acquired by Robinhood] and math teacher) and Alp (CTO, ex-Stripe and Amazon), plus two other exceptional founding engineers.
We move fast, care deeply about craft, and obsess over delighting users. If you're interested, email alp@goblinsapp.com :)
PlantingSpace | Full-time | Remote (EU time zone) + Quarterly Meet-ups | https://planting.space
We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, Material Sciences, and more.
This is an opportunity for senior engineers and product managers to join us at a moment and shape a deep-tech product from its earliest stage.
We're currently seeking talented individuals for the following openings:
* Program Synthesis Engineer
* Bayesian Software Engineer
* Senior Product Manager
Learn more, see role details, and apply via: https://planting.space/joinus/

Kadoa | Web Scraping/Software Engineer | Remote | Full-Time | https://kadoa.com
We’re automating web scraping at scale with AI. Web scraping used to be the same for decades (writing and maintaining rule-based scripts for each source), and we're fully automating that process with LLMs. We're also heavily focused on making ethical scraping the default (robots.txt checks, rate limiting, any custom compliance rules), as we've seen the negative impacts of malicious AI crawlers first hand.
But we can't do it alone. We are looking for people who share our passion for software craftsmanship, data, and AI. We are growing fast, have a “no-bullshit” policy, and try to minimize the distance between the code you write and the customers who use it. We iterate to greatness :)
We're currently looking for a senior web scraping engineer: https://www.kadoa.com/careers/web-scraping-engineer
If that sounds like you, please email me at (adrian at kadoa dot com) and mention HN in the subject line. Ideally you include an ETL or scraping project you've been working on in the past.
