We are looking for a top-of-the-range front-end developer to craft the visual interface for a new company which is building the pinnacle element of AI and human intelligence.

​

We’re building the apex interface for decentralized AI that rivals OpenAI’s chat interface in beauty and belongs to everyone. Our brand draws from the alchemical philosopher’s stone: a

holy union of intelligence and humanity, turning AI into a digital commodity; gold. You’ll turn studio-grade design systems and motion specs into living, breathing product surfaces.

The web app chat interface should be 1:1 to Figma/designs with impeccable craft.

​

What you’ll build

​

• Chat UI with real-time streaming, model switcher, searchable history, and a “temporary / incognito” mode
• A cohesive design system with micro-interactions and page transitions that feel elegant
• Motion that respects performance and accessibility
• Interfaces that rival OpenAI’s polish while expressing our distinct aesthetic
• Simplistically sacred, sharply futuristic

​

What proves you can do it

About Affine

​

Affine is building an incentivized RL environment that pays miners for making incremental improvements on tasks like program synthesis and coding. Operating on Bittensor's Subnet 64 (Chutes), we've created a sybil-proof, decoy-proof, copy-proof, and overfitting-proof mechanism that incentivizes genuine model improvements. Our vision is to commoditize reasoning—intelligence's highest form—by directing and aggregating the work-effort of a large, non-permissioned group on RL tasks to break the intelligence sound barrier.

​

Overview

​

We're seeking an exceptional ML Engineer to build and optimize the infrastructure for our competitive RL environment. You'll architect systems where validators identify models that dominate the Pareto frontier across multiple environments, creating a winners-take-all dynamic that forces continuous improvement. Your engineering expertise will be critical to scaling our incentivized RL approach and enabling fast advancement in model intelligence through directed competition.

​

Responsibilities

​

Distributed RL Competition Infrastructure

​

• Design and implement scalable evaluation systems for models competing across multiple RL environments
• Build Pareto frontier tracking systems that identify dominating models across all evaluation tasks

• Create fault-tolerant systems handling continuous model evaluation and ranking updates

​

Post-Training & Improvement Pipeline

​

• Architect systems enabling miners to download, improve, and resubmit Pareto frontier models
• Implement GRPO, PPO, and other RL algorithms optimized for program synthesis and coding tasks
• Build infrastructure for incremental model improvements with efficient fine-tuning pipelines

• Create automated systems for detecting genuine improvements vs. gaming attempts

​

Validator & Evaluation Systems

​

• Build high-throughput model evaluation infrastructure across multiple RL environments
• Implement efficient Pareto frontier computation algorithms for multi-objective optimization
• Develop real-time leaderboard systems tracking model dominance and miner contributions
• Create robust validation mechanisms ensuring fair competition and accurate rankings
• Build inference load balancing systems for publicly available model serving

​

Incentive & Anti-Gaming Mechanisms

​

• Implement cryptographic proofs for model ownership and improvement verification
• Build systems to detect and prevent sybil attacks across multiple miner identities
• Develop decoy-proof evaluation ensuring models can't be optimized for specific test cases
• Create copy-detection algorithms identifying unauthorized model cloning
• Design overfitting prevention through dynamic evaluation set rotation

​

Performance & Scale Engineering

​

• Optimize evaluation throughput for handling 1000+ model submissions daily
