Read the overview of this opportunity to understand what skills, including and relevant soft skills and software package proficiencies, are required.
The Opportunity
Some engineers join a team. Others get in early enough to help shape what the team becomes.
This is one of those opportunities.
We're looking for an ambitious Full Stack Engineer with a strong backend focus who wants real ownership from day one — not "join a team and pick up tickets." You'll be joining one of NYC's fastest-growing start-ups , helping build and scale a product that's already operating at serious volume.
Billions of interactions. Rapid growth. Serious backing. A product with genuine momentum.
If you're hungry, technically sharp, and want to be one of the engineers helping shape what comes next, keep reading
What You'll Do
- Design, develop, and maintain software systems
- Collaborate with cross-functional teams to integrate technology solutions seamlessly
- Focus on back-end web development, including programming and debugging
- Implement scalable solutions
- Contribute to all phases of the software development lifecycle
About You
You're looking for the opportunity that could define your career.
You've probably spent your spare time building side projects, launching apps, competing in hackathons or interning with ambitious start-ups because you genuinely love creating products. You enjoy solving difficult problems, learn incredibly quickly and thrive in environments where ownership is expected rather than given. You don't wait for instructions — you identify problems, propose solutions and make things happen.
You'll ideally have a Bachelor's degree at a top university in Computer Science, Software Engineering or a related discipline, and be excited by the pace, responsibility and learning that only an early-stage company can offer.
Required Technologies and Skills
- 1–5 years of software engineering experience
- Strong software engineering fundamentals and Object-Oriented Programming (OOP)
- Proficiency in TypeScript and PostgreSQL
- Experience building backend applications
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
