About us: Absinthe is building the most sophisticated gamification engine for crypto-native incentive programs. Since 2022, our products have reached 50M+ visits and 2M+ active users. We’re a 10 person, well-funded team shipping fast.
The problem we’re solving: Tracking per-user activity across DeFi protocols sounds simple but is surprisingly hard. Want to know how long someone held an LP position, or which users provided liquidity for more than 30 days? That data is on-chain but can’t be efficiently queried today.
We built an indexing framework that turns protocol events into time-weighted balances and point-in-time actions. Adapters map protocol-specific semantics (Uniswap ≠ Aave ≠ Morpho) into a unified model. The engine handles state, TWAP pricing, and exporting data anywhere. With ~100 lines of adapter code, you can track user balances and contributions at a fidelity no one else supports.
Why it matters: This infrastructure underpins analytics, loyalty, and incentive programs across Web3. We see the Absinthe Adapter Library becoming the default developer layer for embedded finance.
The role: We’re hiring a Full-Stack Engineer to own features end-to-end schema design, wiring GraphQL, polished frontends, and deployment. Our stack: Next.js, Hasura, dbt, MotherDuck/DuckDB, GraphQL, and in-house Web3 indexing. See open positions here: absinthe.network/careers#open-positions
Get involved: - Explore product functionalities at: https://guides.absinthe.network
- Explore the Adapter Library docs: https://docs.absinthe.network/
- Join our Slack community to hack on adapters and connect with the team: https://join.slack.com/t/absinthecommunity/shared_invite/zt-...

We all know that healthcare is broken. In large part, this is because too much quality, pricing, and access data has been hidden from view, and there are too many intermediaries creating complexity between consumers and the care they need. At Jupiter, we are creating a more direct, flexible, and responsive healthcare system that better serves working-age Americans.
Our triple aim: Improve your health, improve your financials, and make it convenient and easy.
We have built a proprietary dataset of over 12 million direct pay rates across 40,000 providers, covering all types of sites of care in the US, from hospitals, surgery centers, imaging, diagnostics, specialists, primary care, urgent care, virtual care, physical therapy, dental, and vision.
We are now building out our consumer search product which we aim to scale up rapidly in 2026.
We are looking for a Founding Engineer energized by our mission and eager to be part of the founding team at a startup tackling a massive market.

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. (Preview: https://youtu.be/SH9UomzBMUs)
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 we've worked on in the past:
→ 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 and limited CPU).
→ 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 :)

What Cursor has done to revolutionize coding, we are looking to do for revenue. Every large company spends 40-50 cents of every dollar they earn on sales & marketing, and it’s very inefficient because data lives in so many different systems, sales reps are stretched thin doing manual work, and products are rapidly evolving.
It’s why we are building the agent and intelligence framework for enterprise scale GTM that guides every sales motion across the funnel — from SDR outreach to AE deal strategy to cross-sell and expansion. It’s an intelligence layer that sits on top of every sales tool and with external browsing that is then customized to your specific products & GTM motions.
It’s a massive technical challenge: - Intelligence at scale: modeling millions of accounts, real-time signals, and contextual history into per-account reasoning agents. - AI Agents & Chat: designing systems across “push” (recommendations) and “pull” (interactive assistants), with extensible skills customers can train themselves. - Data & Infrastructure: creating a new framework for real-time, per-customer agents that simplifies pipelines, scales efficiently, and cuts costs (we’ve already cut cost per account by 50% through smarter eval-driven approaches). - Wall-to-wall product: from self-serve UI to Slack integrations, from predictive models to generative copilots — we’re building an AI operating layer for GTM.
Why Join Engineering at Actively: - Customer-driven impact: engineers directly go onsite and spend time with customers, deploying agents that reshape workflows at companies like Samsara and Justworks. - Category creation: there’s a huge opportunity to build the pre-dominant AI company for GTM with a massive TAM - Cutting-edge AI: opportunity to push the frontier of reasoning agents, eval-driven development, and scalable intelligence. - High-caliber peers: we’re ex-Instacart, Scale AI, Stanford AI researchers, and operators who’ve built at scale before.

Phosphor builds recursively self-improving systems (via malleable software and natural language interfaces) to enable the efficient development and financing of the physical world (infrastructure, energy, real estate).
Our product is built around a powerful object model which combines document editors with proprietary programming languages for financial modeling, computable contracts, etc, in order to build one of the more unique RLHF feedback loops that we've seen to date.
A primary technical bet is that if we can productize version control properly, we can capture annotated "diffs" of user information with user-validated annotations. By doing so, we create path-dependence, which enables us to specify system-level goals for agents to solve for.
Our product is similar a combination of Linear and Wolfram, with components and objects that enable advanced financial modeling, legal/regulatory analysis, and geospatial analysis of infrastructure development opportunities.
We're venture-backed by one of the best deeptech funds in the market and are hiring for roles spanning product engineers, CRDT wizards, and compiler/calculation engine leads.

Narrative has been building a data collaboration platform designed for simplicity and ease of use since being founded in 2016.
Our primary strength is functioning as a data marketplace where we differentiate ourselves by automatically standardizing data, making platform data accessible through the Narrative Query Language (NQL), giving data providers the ability to define row-level access and pricing policies, and making it easy to deliver data to a variety of destinations using our "Connector Framework".

WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.
We’re hiring on the backend to help solve one of the hardest problems in data engineering: building a production knowledge graph from millions of fragmented, inconsistent Chinese corporate records where traditional approaches break down. Our PySpark/EMR/Airflow pipeline is just the foundation. The real challenges are in entity resolution across transliterated names and obfuscated ownership structures, bipartite matching algorithms and inferring relationships. We build our product on top of that with a Django/FastAPI/React stack to help our users access that knowledge graph to analyze and investigate any risks they should be aware of.
If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.
Apply here: https://jobs.ashbyhq.com/wirescreen/158fd72f-fc2f-47a3-bdb5-...
Happy to answer any questions - you can reach out to me here or at leo.green@wirescreen.ai - I'm a recruiter with WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast.

We aren't actually hiring anyone immediately, but we've hired a handful of great engineers from HN and inevitably will need to hire again. We've found having those conversations and keeping in touch is much better than going through the process from scratch each time, as it fast tracks the process a great deal when the time comes. So reach out if you think you're a good fit.
ReciPal is a profitable, growing, bootstrapped, and (have always been a) fully remote company (based in New York) with 6 full-time employees. We make simple software for food businesses - nutrition analysis and labeling, costing, and inventory management. We've been around for almost 15 years now!
You'd be working directly with me, solo founder, our senior engineers, and marketing and support colleagues, and hopefully take on a growing role over time to treat the business like your own. It's a very low key work environment, but independent and plenty of responsibility and ownership for the right person.
Stack includes Rails 8, JavaScript, Postgres, Heroku.
