Product Engineer
Parafin
Remote cryogenics engineer job
About Us:
At Parafin, we're on a mission to grow small businesses.
Small businesses are the backbone of our economy, but traditional banks often don't have their backs. We build tech that makes it simple for small businesses to access the financial tools they need through the platforms they already sell on.
We partner with companies like DoorDash, Amazon, Worldpay, and Mindbody to offer fast and flexible funding, spend management, and savings tools to their small business users via a simple integration. Parafin takes on all the complexity of capital markets, underwriting, servicing, compliance, and customer service for our partners.
We're a tight-knit team of innovators hailing from Stripe, Square, Plaid, Coinbase, Robinhood, CERN, and more - all united by a passion for building tools that help small businesses succeed. Parafin is backed by prominent venture capitalists including GIC, Notable Capital, Redpoint Ventures, Ribbit Capital, and Thrive Capital. Parafin is a Series C company, and we have raised more than $194 M in equity and $340 M in debt facilities.
Join us in creating a future where every small business has the financial tools they need.
About the Position:
At Parafin, Product Engineers are the implemented product experts. We bridge design, product, and backend, which means we're responsible for making sure everything actually works the way it should. We are care about things beyond the specs like understanding why features exist, who uses them, and what problems they solve. You'll own the entire frontend: every transition, every edge case, every state change that happens between a user's action and what appears on their screen.
You don't need to know our exact stack coming in, but you should be strong with JavaScript fundamentals and have shipped real products with React and TypeScript.
What you'll do:
Build polished experiences at scale. Work with design to ship great UI/UX, but also own the less visible stuff that matters like page speed, cross-browser support, mobile responsiveness.
Master the product. Develop deep expertise and opinions in what we're building. Work with product and design to shape what we build, not just execute on specs.
Instrument and optimize. Implement observability for user interactions, core web vitals, and perceived performance.
Craft frontend and product infrastructure. Contribute to build systems, dev tooling, and deployment pipelines. Advocate for a better developer experience. Build internal tools that help the team move faster.
Who you are:
2‑3+ years of experience working in a frontend engineering role
You have an eye for design. You have track record of creating beautiful experiences for the web. You care deeply about user experience and have an understanding of what might make one UI better than another.
You think in systems. You build infrastructure that makes future features easier. You know when to generalize and when to keep things specific.
You're a self-starter. You enjoy building 0 to 1. You're always looking for things that could use some TLC and finding ways to make them better without asking permission.
You care about the details. You care about micro-interactions. You think about what happens when the network is slow, when data is missing, or when users do unexpected things.
You're a good teacher. You know how to explain ideas and trade-offs cross-functionally.
You have opinions. You have thoughts on different state management approaches, how to structure provider hierarchies, and whether that hook should be extracted or kept inline. You can articulate why you'd choose one abstraction pattern over another.
You're always learning. You've tried various coding and AI tools just out of curiosity. You want to know what the latest and greatest are and what problems they solve.
What We Offer:
Salary Range: $190k-$225k
Equity grant
Medical, dental & vision insurance
Work from home flexibility
Unlimited PTO
Commuter benefits
Free lunches
Paid parental leave
401(k)

Research Engineer
Gamma.App
Remote cryogenics engineer job
We're building the creative layer for modern communication. Every month, over a billion people make presentations - but the tools they use to make them haven't evolved in decades. We're changing that, using AI to disrupt a massive market.
📈 Millions of people rely on Gamma to create, teach, and persuade, creating more than 1 million gammas every day.
💻 We see Gamma as the next great workplace tool, combining viral B2C love with a massive B2B opportunity. We believe AI can be a true creative partner: one that understands context, clarity, and taste.
💸 We've reached a $2.1B valuation, crossed $100M in annual recurring revenue, and have been profitable since 2023.
💙 We're an imaginative, passionate team who takes our work seriously, but not ourselves. Our culture is warm, a little quirky, and fueled by curiosity.
About the role

You get energy from small teams doing big things.
You love when design, code, and storytelling overlap.
You default to action, even when the answer isn't clear yet.
You value details, but know when to ship and move on.
You bring both the spreadsheets and the sparkle, equal parts workhorse and unicorn.
You believe AI should amplify creativity, not replace it.
You know kindness and intensity are not opposites.
You like working with people who care deeply: about their craft, their teammates, and the users on the other side of the screen.
Who we are
Gamma is full of imaginative, passionate people who take their work seriously but not themselves. The culture is warm, a little quirky, and fueled by curiosity. It's the kind of place where you'll debate a pixel on Monday, laugh over someone's keyboard setup on Tuesday, and ship something remarkable by Friday.
We care about craft, move with intention, and don't mind getting a little scrappy. It's fast, creative, and occasionally chaotic - but that's what makes it interesting.
Here's a bit about what it's like to work here, from people on the inside:
We asked the team what makes Gamma, Gamma. Here were some of their answers:
"quirky, inspiring, fun, a little wild in the best way"
"You can have an idea and just run with it."
"Everyone's talented and humble - the mix keeps you sharp."
"We ship cool stuff, learn a ton, and laugh a lot doing it."
Meet the team
We're a team of dreamers and doers building in beautiful San Francisco 🌉
We're kabbadi enthusiasts, pickleballers, dog herders, woodworkers, keyboard nerds, potters, and more - and we can't wait to meet you!
