Senior Full Stack Engineer

Location: San Francisco or New York - hybrid

Work type: Permanent, full-time

Equity: 0.25%-0.75%

The Opportunity

This is not a role for someone who wants to own one service and hand the rest to another team. You will be close to the product, the users and the decisions that shape both.

A fast-growing, VC-backed start-up is building the operating system behind high-skilled US immigration. Following $10M in revenue last year, the business is targeting significant growth and is expanding a deliberately small engineering team.

The challenge is broad: simplify complex legal workflows, rebuild the customer portal and strengthen the architecture beneath a product used by customers and internal specialists every day.

The Role

• Lead improvements across frontend and backend architecture, with a backend lean.
• Rebuild the customer-facing portal and design the APIs behind it.
• Create robust task orchestration for multi-step drafting, review and filing workflows.
• Improve backend services, event pipelines, scheduled jobs and CI/CD.
• Design clear data models, schemas, migrations and access controls.
• Ship polished React interfaces and triage issues across the entire product.
• Work directly with product, customers and operational users to understand what should be built.

The Person

• Deep TypeScript and React expertise, alongside credible backend engineering experience.
• Usually 5+ years in full stack product engineering, with evidence of complete end-to-end delivery.
• Strong API, relational database and systems-design fundamentals.
• Comfortable with Python, Node, Django, FastAPI or an equivalent backend environment.
• Thrives in a small start-up where ambiguity, autonomy and user contact are part of the job.
• Can explain technical trade-offs to non-technical colleagues and make sensible decisions independently.
• Bachelor's degree or higher, preferably in computer science or a related discipline.
• Experience as an early or founding engineer, leading others or contributing to open source would be valuable.

What Is on Offer

• $200,000-$250,000 base salary, with flexibility to $300,000 for an exceptional candidate.
• 25%-0.75% equity.
• High ownership and direct influence over product and architecture.
• Focused standard working hours, without an expectation of routine weekend work.
• Hybrid working in San Francisco; New York candidates can work remotely until the local office opens.
• Relocation support plus OPT, H-1B transfer and TN visa support.
