We're building trade software that actually works.
Our first product is duty drawback. Every year $10B in potential refunds are left unclaimed. Data is unstructured, fragmented and trapped in legacy systems that don't talk to each other. We're helping companies organize and understand their trade data. Leveraging the wedge product, we intend to quickly grow beyond our initial product.
You'll work with a small (5-10), well-funded and experienced team. We have paying customers and are scaling up quickly in an established space. Our engineering culture emphasizes simplicity, autonomy and end-to-end ownership. Node, Typescript, React, PostgresQL

We build Measurement While Drilling (MWD) equipment — and we love it. That passion helped us capture the majority of the North American oil & gas market, and now it’s fueling our geothermal innovation, building underground navigation systems for the next generation of clean energy.
We’re now looking for a Data Wrangler to help us make smarter, faster decisions with our data. This role blends data engineering and data science: wrangling quirky file formats, structuring messy datasets, and turning it all into live tools that guide company strategy. Starts part-time with the opportunity to grow into a full-time, career-defining role. What you’ll do
Partner with the CEO + stakeholders to translate business needs into pipelines, dashboards, and tools. Build ETL pipelines, write parsers for proprietary formats, and maintain relational databases (PostgreSQL, MySQL). Create interactive dashboards/apps with Dash, Streamlit, or similar (we avoid Tableau/Excel hell). Deliver insights via live web apps where data isn’t static — it’s explorable. Tech we use Python, SQL (PostgreSQL/MySQL), S3, modal.com. Bonus: React/web dev experience to shape customer-facing real-time tools. Why you’ll like it here You’ll own projects end-to-end, avoid over-engineering (no Kubernetes, no Airflow — just the right tools), and directly influence decisions. As our company and data needs grow, so does your role. If this sounds fun, email ken@erdosmiller.com with your background and what excites you about wrangling data.

Looking for:
1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.
2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)
3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)
4. Broad experience across multiple programming paradigms, platforms and software stacks.
5. Demonstrated care for the software craftsmanship (which can take many forms).
6. Great spoken English, and ability to communicate 9am to noon in New York time zone.
We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.
Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)
We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We’re especially keen to talk to Staff Engineers (backend) and Senior AI Engineers (e.g. LLMs and the scaffolding around, computer-use agents)
Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

YC has been building ever-more ambitious software for founders to succeed -- since Garry returned. In the last year, our team delivered:
* Safe tools that has processed $1B+ in seed funding in last 4 batches
* Fundraising CRM for founders manage their fundraise -- used by all founders
* Work at a Startup has 1M+ candidates on it, with 1000s of hires/year
There are ton of ways we see YC Software benefitting our alumni and investors -- and we want founder/founding engineer minded people to drive each into standalone products.
Yet in reality, we're a team of 14 full-stack product engineers, the company is 85 people, and we intend to stay small and scrappy. I was the 7th engineer at salesforce and loved the early stage, and we get to be that way at YC... indefinitely.
YC is also knee-deep in applying AI tools and techniques across all of our product surface areas, and investor-focused work is no exception. We’re happy to share more when we chat in person.
We also want to work with people who love building full stack web apps. While our stack is Rails, React and Postgres, mostly we’re just a bunch of pragmatic builders who are excited about shipping and having impact.
Two roles are posted below: Investor Software and Post Batch (all SW after the batch).

Looking for something more meaningful? How about the opportunity to have a direct impact on the property maintenance experience for hundreds of thousands of residents?
Welcome to the future of property maintenance. Property Meld’s vision is to radically improve how the property management industry handles property maintenance. If you’ve ever had a maintenance issue at your housing rental, you know how much of a pain it can be to get it fixed quickly and reliably. It doesn't have to be this way. We're rethinking the entire property maintenance experience from the ground up with two things in mind - first, driving the cost of doing maintenance to the absolute minimum, and second, providing an experience to residents and property owners that makes them want to stay with their property manager. If you are excited about turning something that has historically been a negative experience (maintenance) into a positive experience, we'd love to talk with you.

Do you want to develop software that helps scientists, doctors, and historians discover breakthroughs? Join our small, fully-distributed software development team to help connect scholars of all disciplines with peer-reviewed journal articles.
Our company has been remote-first since we began in 2011. You’ll join a team with plenty of experience putting into practice what works well remotely, and avoiding what doesn’t. Third Iron has never taken VC money, and we’ve never had layoffs. Our approach to hiring and selling our products helps us feel confident that this pattern will continue far into the future.
Third Iron software is used by researchers at over 1,500 libraries, including universities, hospitals, corporations, and government agencies located in over 35 countries.
In a refreshing change from advertising-dependent tech companies and those who sell user data, we instead have a business-to-business model. We sell our subscription-based services to libraries, and anyone affiliated with one of these libraries can use our software. We do not sell user data. Our focus is on building the best software to enable research that changes the world.
We’re looking for a developer interested in full-stack work, since we have a variety of upcoming initiatives, some being mostly front-end, some being mostly back-end, and some a balance of the two.
The front-end of our stack primarily consists of JavaScript, using EmberJS for two major projects, and React for two others. Our backend is written in NodeJS, and features data storage using PostgreSQL, Elasticsearch, and CouchDB, and hosting primarily on AWS and HEroku.
If you’re interested in this fully remote position, we're interested to chat with you! Please email careers@thirdiron.com or apply at https://thirdiron.applytojob.com/apply/McK2VdxTuX/Senior-Ful...

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.
