Senior Software Engineer

Full-Stack Builder for an AI-First Venture Studio.

We’re not hiring just another software engineer. We’re hiring a senior product-minded software engineer who can lead technical direction, architect scalable systems from 0→1, and mentor other engineers while staying close to users and product impact. Great engineers build elegant infrastructure. Great product engineers go further. They ask what should be built, not just how. They care about usability, business impact, and long-term technical health.

They thrive on solving user problems, not just implementing specs.

Gitwit is a venture studio focused on building AI-native startups. Over the next 5 years, we’ll launch 15+ new software companies from scratch, with a rigorous process of insight discovery, rapid prototyping, building lean MVPs, and user-driven iteration. In the last 18 months alone, ventures we've launched have already created $35 million in valuation, and we’re just getting started. This is a rare opportunity to help shape not just products, but entire companies by working on meaningful problems alongside a team built for velocity, learning, and invention.

At Gitwit, we’re building startups the hard way: from first principles. That means beginning with real user pain, behavioral data, and frontline discovery. Our product engineers work closely with sales, research, design, and strategy teams to translate what users need (and wish existed) into software that feels sharp, useful, and inevitable.

You’ll be embedded in small, cross-functional teams with autonomy to define technical direction and product scope. You’ll move fluidly between shipping prototypes fast and building production-grade applications that can scale with traction.

We’re not looking for someone to just write code. We’re looking for a builder who ships daily. Someone who makes new features, improvements, and bug fixes that create raving fans and fuel tighter user feedback loops.

To win in the marketplace, great startups need more than good ideas. They need technically sound, delightfully usable products that evolve fast. That’s where you come in.

You’ll bring technical depth, architectural judgement, and product intuition to early-stage ventures. You’ll help define what gets built, why it matters, and how it scales.

This is a rare chance to be the kind of engineer who creates new value, not just executes on it. If you want a seat at the product table, not just a terminal, let’s talk.

• Ship code daily - startup ventures win by being the fastest to new, useful features and fixes
• Lead technical architecture for MVPs and early production systems.
• Mentor other engineers, raising the bar on code quality, testing, and delivery.
• Help shape the product, not just implement someone else’s roadmap
• Build full-stack web and mobile apps with real-time feedback loops
• Wire up AI frameworks (e.g., OpenAI, Anthropic, Gemini) into intuitive user products
• Own the product experience from early sketch to first traction
• Kill bad ideas fast and scale good ones quickly

• Frontend:
  React + Type Script, built in close collaboration with designers
• Backend:
  NestJS + Type Script
• Databases:
  Postgre
  
  SQL and Mongo
  
  DB, depending on venture needs
• Dev Ops: AWS, GCP, Git Hub Actions
• AI:
  OpenAI, Anthropic, and Gemini APIs with thoughtful model selection and prompt design
• You’ll sit at the center of our venture creation engine, focused on shaping two to three startups each year.
• You can choose to stay with a venture you launch or remain in the studio, building new ones. Both paths include equity.
• You’ll collaborate cross-functionally from day one. Engineering, UX, strategy, research, sales, and marketing all have a seat at the table.
• You won’t get specs. You’ll get real problems to solve and the freedom to build the right thing.
• You’ll be a technical leader and product co-creator, not just a code executor.
• You don’t need to have done it all. We’ll grow with you.

• 5+ years of professional full-stack software engineering experience
• Previous startup experience or a strong desire to work in early-stage environments
• Proven experience in building software from the ground up
• Ability…
