Compiler Frontend Engineer

About Winixx

Winixx Inc. is a New York-based technology holding company operating a portfolio of over 35 SaaS platforms across freight, fleet management, financial infrastructure, and market intelligence. We are building WinixxOS — a distinctive, AOSP-based operating system powering a full lineup of consumer hardware — and, over a multi-year horizon, .wnx, a proprietary programming language designed to be announced alongside WinixxOS. This is founding-team language engineering: you would be shaping the core type system, memory model, and syntax of a new language from its very first version, not extending someone else's spec.

Role Summary

The Compiler Frontend Engineer implements and tests components of the .wnx lexer, parser, and type checker, working alongside senior engineers to build out the language's core semantic analysis.

What You'll Do

• Implement and test components of the lexer, parser, and type checker
• Support the device-class targeting system's type-level implementation
• Write compiler test suites covering syntax, type-checking, and diagnostic behavior
• Fix bugs and edge cases identified through internal dogfooding of the language
• Contribute to language specification documentation

What We're Looking For

• 3+ years of experience in compiler or interpreter engineering, or comparable coursework/project experience with a real implementation to show for it
• Working knowledge of parsing techniques and type-checking fundamentals
• Familiarity with at least one modern language's compiler internals (Kotlin, Swift, Rust, or similar)
• Bachelor's degree in Computer Science or equivalent experience

• Competitive base salary commensurate with experience
• Performance bonus program tied to individual and company milestones
• Visa sponsorship available for the right talent
• Full-time role with a minimum one-year commitment
• A rare opportunity to help design and build a production programming language from scratch
• Collaborative, mission-driven team environment
• Paid time off and company holidays
• Professional development and continuing education support

Winixx Inc. is an equal opportunity employer. We evaluate all applicants on the basis of qualifications, experience, and demonstrated ability without regard to race, color, religion, sex, national origin, disability, veteran status, or any other characteristic protected by applicable law.

This is a full-time position with a minimum one-year commitment, on a multi-year (5-year horizon) language development effort. Visa sponsorship is available for candidates with the right qualifications and experience.

The compensation range reflected in this posting represents the minimum and maximum target range for this position. Individual pay within the posted range is determined by a candidate's demonstrated experience, educational background, skill set, and geographic location. Final compensation is established at the time of offer and may fall anywhere within the stated range based on these factors.

Compensation ranges reflect national US market data and are subject to change. Additional forms of compensation may include performance bonuses, equity participation, and other benefits as outlined in your offer documentation.
