About Alpha

An early-stage open-source platform building the feedback loop that powers smarter, faster, and more efficient large language model (LLM) applications—turning real-world data into continuous improvements.

What We're Building

• A unified model gateway for inference
• Seamless collection of metrics and feedback
• Optimization tools for prompts, models, and inference strategies
• Native experimentation and fallback support
• A data-and-learning flywheel for LLMs

The Platform Brings Together

• Inference: One API to manage all LLMs with minimal latency overhead
• Observability: Inference data and user feedback fed directly into your systems
• Optimization: From prompt engineering to fine-tuning and reinforcement learning
• Experimentation: Built-in A/B testing, smart routing, and fallback capabilities

The Role

We're hiring a Founding Member of Technical Staff with expertise in front-end or design engineering. We encourage cross-functional ownership—combining product thinking, research instincts, and technical craftsmanship. Your first major project would likely be developing an open-source UI—like a console that visualizes and controls model behavior, experimentation, and optimizations. You will design and build intuitive interfaces for observability data we already collect.

What We Offer

• Highly competitive compensation (salary, equity, and benefits)
• The chance for your work to be open-source and highly visible
• Opportunity to expand skills into new areas—infra, ML, and beyond
• A small, focused, in-person environment emphasizing technical quality
• Backing from top investors in AI and developer tools

What We're Looking For

• A strong technical foundation with experience leading large projects (starting with the observability dashboard)
• Passion for building delightful developer interfaces
• Front-end expertise—experience with Remix, Tailwind, especially React
• Eagerness to learn and contribute across domains
• Willingness to work in person, five days a week, in New York City
