Senior Software Engineer (Web + Mobile)

The Opportunity

We’re looking for a passionate Senior Software Engineer to collaborate on building the next-generation AI coding platform. This is a rare opportunity to join an early-stage company founded by Andrew Filev (founder of a unicorn startup) — to help scale it into a thriving, world-changing business. Together, we’re shaping the future of software development — closing the gap between idea and reality, and influencing not only how code is written, but how progress happens across every field that depends on software.

Key Responsibilities

You’ll take ownership of designing and building key features. Our stack currently consists of TypeScript, Kotlin, and Rust, and you may be expected to work across all of them. This is not a “just code what’s assigned” role — we’re looking for people with a product mindset, who think deeply about users, bring ideas for product growth, and aren’t afraid to propose and launch new things.

We value people who make things happen through their own enthusiasm, rather than waiting for managers to tell them what to do. Here, individual contributors hold the highest status — they are the driving force behind the company’s progress. You’ll work alongside top professionals in an environment that celebrates curiosity, creativity, and results.

Essential Qualifications

• 10+ years of experience building complex, production-grade applications, including deep expertise in React Native and backend development experience in Java / Kotlin / TypeScript / Python / Rust.
• Experience in mobile application development.
• Strong computer science foundation combined with a deep understanding of modern software architecture and design principles — and a proven record of applying them effectively in real-world, user-facing products.
• Product mindset — you think beyond code, care about the “why” behind the feature, and proactively contribute ideas that make the product better for users.
• Strong sense of ownership — you take initiative, drive projects from concept to launch, and thrive when given autonomy and accountability for outcomes.
• Deep familiarity with AI assistants, a solid grasp of the evolving AI landscape, and the ability to translate trends and capabilities into practical product improvements.
• Proven ability to collaborate effectively within a fast-moving, cross-functional team — communicating clearly, sharing context, and supporting others to achieve shared goals.
• Passion for continuous learning, experimentation, and innovation — you stay curious, adapt quickly, and always look for ways to push the boundaries of what’s possible.
• Comfort working in dynamic, fast-changing environments — ideally with prior experience in start-ups or early-stage teams where clarity must often be created, not awaited.
