Take products and features from initial concept through production launch.
Improve application performance, reliability, security, and scalability.
Work closely with founders, engineering leaders, and customers to solve meaningful problems.
Own technical decisions and remain accountable for how your software performs after launch.
What we’re looking for:
3+ years of professional software engineering experience, with clear examples of production software you personally built and shipped.
Depth in full-stack or backend development. You do not need to specialize in both.

Backgrounds that stand out Engineering experience at a leading startup or a technology company known for strong engineering talent.
Early engineering responsibility: launching products, building core systems, or helping a small team scale.
A degree in computer science, engineering, mathematics, or a related discipline from a leading university.
Evidence of exceptional ability through technical achievements, research, open-source contributions, or products you’ve built.
We value strong academic and company backgrounds alongside clear evidence of individual contribution, technical depth, and ownership.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
