Senior Backend Engineer

Secfi is building the private wealth stack for employees and executives with equity.

Private markets are where most wealth is created today, and they're notoriously hard for individuals to navigate. The best financial advice has always been a luxury, reserved for the ultra-wealthy, delivered by private bankers.

Even those who can afford an advisor often find that most have a blind spot when it comes to pre-IPO company equity & stock options. It's a black box for most in the industry.

Meanwhile, startup employees give years of their lives. Intense work, real sacrifice. Then the company finally has its exit, and they get burned. They pay more tax than they need to. They don't have access to private bank liquidity solutions. They mishandle their shares. They can leave millions on the table, on the single biggest financial decision of their life.

We're changing that!

Secfi is putting sophisticated equity strategy in the hands of the people building the world's most innovative companies.

We work with the builders behind the best tech companies on the planet. We're doubling revenue year on year, growing AUM at over 200%, and we're trusted by employees from companies like Canva, Stripe, SpaceX, Databricks and Anthropic.

We're indirectly invested in more than half the IPOs of the biggest tech brands you know, and we help the people who built them with something deeply personal: their finances.

We're at an inflection point. Demand is climbing, and we're expanding fast on all fronts. A great fintech is a strong blend of financial products and technology, and we're pushing hard on each.

The financial products. The financing and wealth platforms that already drive our revenue, with a fast-growing user base. Now we're deepening them. Automating what's still manual, shipping the features that turn a strong business into a category leader. It's the highest-leverage work in the company: every improvement compounds straight to the bottom line.

The technology. Maeve is our agentic financial planner, and it's becoming the interface for everything Secfi does. Not a feature bolted onto the side, but the hub: the connective layer between our financing, wealth and planning products, and the way customers interact with all of it.

We've merged frontier AI with each person's real financial data and our proprietary calculation engines to bring clarity to the most complex decisions someone will ever face. The more context it holds, the better it gets. The Forecaster predicts the future value of private equity, something only investment banks can do today. We're building it for everyone.

This is a genuinely hard space. Many moving parts, uncertain outcomes, probabilistic by nature, where accuracy and trust are everything. Whatever advice we give has to be right, every time.

It's early enough that the biggest problems are still unsolved. The people who join now are the ones who'll solve them.

We're looking for a Senior Backend Engineer to build the systems behind some of the most consequential financial decisions people ever make.

Let's be straight about what this is, and what it isn't. If you're chasing scale problems - millions of concurrent users, distributed systems at the edge of what infrastructure can handle, this isn't the role. Our user numbers are around 60,000 & growing.

The real complexity here is in the domain and the nature of the problems you’ll need to solve: probabilistic financial modelling, tax logic across multiple jurisdictions reverse engineered into software, forecasting the value of assets that don't have a public price, accessing data that needs to be accurate.

The math is hard. The correctness bar is absolute. Get it wrong and someone makes a…
