Full Stack Engineer (Backend Leaning) - Start Up - NYC

$130k - $200k
Full-time

Initi8 Recruitment

Ambitious Full Stack Engineer (Backend Leaning) | Build From 0 → 1 | NYC

The Opportunity

Billions of interactions. A small, sharp team. And a backend that has to keep up.

Most engineers join a company after the big decisions are made. This is a chance to get in early enough to make some of them.

One of NYC’s fastest-growing start-ups is hiring a Full Stack Engineer with a strong backend focus.

The product is already running at serious scale, with billions of interactions and a client base that keeps growing. They have major investment behind them. Now they need engineers who want ownership from day one, not a ticket queue.

What you’ll actually be doing

  • Owning backend systems end to end. You’ll design, build and ship services in TypeScript and PostgreSQL that handle real traffic at real scale.
  • Solving scale problems. At billions of interactions, query performance, data modeling and system design have a direct effect on the business.
  • Shipping across the stack. You’ll lean backend but go wherever the problem is, working closely with product and commercial teams
  • Shaping how things are built. You’ll have a say in architecture, tooling and engineering culture.
  • Going from idea to production. You’ll take work from first sketch to live deployment, and own it once it’s out there.

You’ll probably recognize yourself here

  • You have 1–5 years of software engineering experience and you’ve built backend applications that real people use
  • You’re strong in TypeScript and PostgreSQL, with solid fundamentals and a good grasp of OOP
  • You build things for fun: side projects, shipped apps, hackathons, early-stage internships
  • You learn fast, spot problems before anyone asks, and come with a fix rather than a question
  • You want the pace, responsibility and steep learning curve that only an early-stage company gives you
  • A CS or Software Engineering degree (or similar) is a plus, but what you’ve built matters more

The Company

This organisation is a fast-growing, red-hot technology firm that provides a platform connecting diverse users with commercial opportunities through authentic content. They are hitting startling numbers with billions of interactions and a client base growing quickly. Backed by major recent investment and already delivering exceptional growth, they're scaling at serious speed.

They are a focused, high-IQ team who are prepared to do what is needed to get the job done. The team comes to the office every day and always achieves something before they head home.

Why You Should Join This Job

This is a company going places — fast. Backed by serious momentum, strong investment, and an ambitious vision, they're building something people genuinely believe in. The energy across the team is high and the talent density is exceptional.

The people you'll work with could work anywhere, but they believe in this mission and have chosen to build here. Joining now puts you at the heart of that growth. As one of the early engineers, you'll have real influence on the product and the chance to accelerate your career massively. You won't just be another hire — you'll help shape the company.

You will be well rewarded: strong compensation, meaningful bonuses, and equity are all on the table.

Location

Manhattan , NYC (Financial District). This is a full-time, on-site role working in the office, 5 days per week. Not based in New York? No worries — all expenses will be covered for interviews and meetings, and you'll be well supported by the team throughout your move to New York.

The Money

$130,000 – $200,000 + Bonus + Equity
