Senior Software Engineer — Agentic Coding (AI Training) About The Role What if your software engineering expertise could define how the next generation of AI writes, debugs, and ships code on its own? We're looking for Senior Software Engineers in London to work at the frontier of agentic AI — building, evaluating, and improving autonomous coding systems that can reason through complex problems, execute multi-step plans, and produce production-quality software with minimal human intervention. This is where deep engineering skill meets the most transformative technology of our time. You'll work on real problems that push the boundaries of what AI agents can do — and your code, judgment, and architectural thinking will directly shape how these systems evolve. This is a fully remote, flexible contract role. If you're a senior engineer who's excited about agentic AI and wants to work on problems that genuinely matter, we want to hear from you....

What if your expertise in Rust could directly shape the infrastructure behind the world's most advanced AI systems? We're looking for a Senior Rust Engineer to design and build high-performance data pipelines, annotation tooling, and evaluation systems that power cutting-edge AI research and production workflows. This is a fully remote contract role working alongside leading AI labs on real, high-impact engineering challenges — not toy projects. If you live and breathe Rust and care deeply about performance, safety, and correctness, this is the work you've been waiting for. Organization : Alignerr Type : Hourly Contract Location : Remote Commitment : 20–40 hours/week What You'll Do Design, build, and optimize high-performance systems in Rust supporting large-scale AI data pipelines and evaluation workflows Develop full-stack tooling and backend services for data annotation , validation, and quality control at scale Identify and...

Software Engineer – Machine Learning (AI Training) About The Role What if your machine learning expertise could directly influence how the most advanced AI systems in the world think, reason, and write code? We're looking for experienced ML engineers in London to evaluate AI-generated machine learning solutions — catching errors, improving quality, and helping frontier AI models get genuinely better at one of the hardest things they do. This is a fully remote, flexible contract role. Work asynchronously on your own schedule, from wherever you are. No fixed hours, no meetings — just high-impact, expert work that matters. Organization: Alignerr Type: Hourly Contract Location: Remote (UK-based) Commitment: Flexible, project-based What You'll Do Review and evaluate AI-generated machine learning code — including Python, TensorFlow, PyTorch, and scikit-learn — for correctness, efficiency, scalability, and clarity...

Senior Optimisation Scientist UK Austria or Greece Role type: Full Time Contract or Permanent Location: UK timezone +/- 2 hours, Remote Preferred Start Date: ASAP Life as a Satalian (who we are) As an organisation, we push the boundaries of data science, optimisation, and AI to solve the most complex problems in industry. Satalia (a WPP company) is a community of individuals devoted to working on diverse and challenging projects—allowing you to flex your technical skills whilst working with a tight-knit team of high performing colleagues. Led by our founder and WPP Chief AI Officer Daniel Hulme, our ambition is to become a decentralised organisation of the future. This involves developing tools and processes to liberate and automate manual repetitive tasks, with a focus on freedom, transparency and trust. At the core of our thinking is an approach to wellbeing and inclusivity: we unpack human behaviour and unpick prejudice to ensure a safe and inviting...

What if your data science knowledge could directly shape the intelligence of tomorrow's most advanced AI systems? We're looking for Data Science Experts to stress-test, evaluate, and improve cutting-edge language models — exposing their blind spots, correcting their reasoning, and setting the standard for what great data science looks like. This is a fully remote, flexible contract role designed for experienced data scientists, statisticians, and ML practitioners who want to do meaningful, intellectually stimulating work on their own schedule. Organization : Alignerr Type : Hourly Contract Location : Remote Commitment : 10–40 hours/week What You'll Do Design Advanced Challenges — Develop complex, domain-specific data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more Author Ground-Truth Solutions — Write rigorous, step-by-step...

AfterQuery is seeking experienced Product Managers to create and evaluate product-management reasoning challenges for our AI training modules. In this remote, flexible role, you will design realistic product scenarios — prioritization calls, spec reviews, stakeholder trade-offs — that test an AI model’s ability to reason like a strong PM, and grade model responses against real product judgment. Why Apply Competitive Compensation: attractive hourly rates that reward your specialized expertise Innovative Impact: join a YC-backed startup revolutionizing AI with high-caliber expert content and insights Flexible Engagement: a remote, asynchronous role that lets you contribute to pioneering projects on your own schedule Responsibilities Develop product cases, PRD critiques, and prioritization exercises that challenge AI models on realistic product decisions Evaluate and score model responses, providing detailed feedback on product...

About The Role What if the code you write could directly shape how the next generation of AI understands and generates software? We're looking for Software Engineers in London to build, evaluate, and improve AI-generated code — helping train AI systems to think like real developers. You'll write solutions, review AI outputs, and provide the expert-level feedback that makes AI coding assistants smarter, safer, and more reliable. This is hands-on engineering work at the frontier of AI development — not theoretical, not bureaucratic, and not boring. This is a fully remote, flexible contract role. If you can write clean code and explain your reasoning, we want to hear from you. Organization: Alignerr Type: Hourly Contract Location: Remote Commitment: 10–40 hours/week What You'll Do Write, debug, and optimize code across a range of languages, frameworks, and problem domains Review and evaluate AI-generated code for correctness,...
