Senior Full Stack Software Engineer

About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Contribute to a desktop software product that runs on multiple operating systems, writing code that spans the user interface and low-level native layers. You will take features from concept to release, add AI-driven capabilities, and have a voice in technical decisions on a small, close-knit engineering group.

What you'll do

• Build and maintain key capabilities of a desktop application used across operating systems.
• Take full responsibility for delivering features, covering both interface work and native components.
• Create and connect functionality driven by large language models.
• Work alongside teammates on platform-specific native code for Windows and macOS.
• Weigh in on system architecture and help set engineering direction.

Requirements

What we're looking for

• A track record of taking product features from idea to launch in a rapidly growing startup or a large, fast-moving technology company, on products with real impact.
• Exceptional depth in one area you care deeply about, shown through things like following AI developments, working with language models or open-source contributions.
• Skill at describing technical choices in plain language to people outside engineering, and willingness to think aloud while solving problems.
• A team-first attitude suited to a small, tightly knit group.
• Meticulous habits and real pride in delivering polished, high-quality work.
• A hands-on, accountable mindset with readiness to take on any task that moves the team forward.

Bonus points

• Working knowledge of TypeScript with React and Node.js, plus Swift or C++ for native development.
• Familiarity with building desktop apps using a web-based framework.
• Hands-on work with AI-powered product features.
• Background at consumer productivity software companies.
• Prior experience founding a company or working at an early-stage startup.
