Salary:
$170K – $230K + Equity + $18K Living Proximity Bonus
Visa Sponsorship:
Not currently offered (may consider exceptional candidates)
About the Role This role is ideal for ambitious engineers with entrepreneurial goals. Many team members are former or future founders, and this opportunity offers a chance to scale a company from $1M to $10M ARR while building tools used by top tech teams shaping the future of software. The team values in-person collaboration and works out of an office in the Williamsburg neighborhood of Brooklyn.
We’re hiring for two types of roles:
SDK Generalists – work across multiple languages and contribute to the core compiler and generator infrastructure.
SDK Language Specialists – lead the development of best-in-class SDKs in Java, PHP, Python, TypeScript, or Ruby.
What You Will Do For SDK Generalists:
Drive feature parity across SDKs — support advanced features like auto-pagination and server-sent events.
Expand SDK support into new languages (e.g. Swift, Rust, Terraform) by building new generators.
Contribute across multiple codebases using TypeScript, Go, and Python.
Collaborate with leadership to help grow the team through recruiting and mentorship.
For SDK Language Specialists (Java, PHP, Python, TypeScript, Ruby):
Define what a high-quality SDK looks like in your language: idiomatic, easy to use, and reliable.
Own core components of the open-source compiler to add key features and improve developer experience.
Stay up to date with language-specific tools and libraries, and engage directly with developers via GitHub and community forums.
Play a key role in hiring and mentoring as the team scales.
Requirements
4–10 years of professional software engineering experience.
Deep expertise in one of the following languages: Java, PHP, Python, TypeScript, or Ruby (for specialists).
Broad technical fluency and the ability to contribute across different languages (for generalists).
Experience in fast-paced startup environments; prior founder experience is a plus.
Strong product thinking and empathy for developer experience.
Eagerness to work in a polyglot environment.
Compensation and Benefits
Salary:
$170K–$200K for Generalists, $200K–$230K for Language Specialists
Equity:
0.1%–0.3%
Living Bonus:
$18K annually for those living near the office
