MeanderX is building AI-powered grid intelligence for renewable energy developers.
The hard part of clean energy is not just building solar, wind, and storage. It is knowing where new energy generation can connect fastest to the grid.
We’re hiring a Senior Full-Stack Engineer to own high-leverage systems end-to-end: AI data analysis pipelines, scraping infrastructure, LLM extraction workflows, internal AI tools, and our customer-facing platform.
You should be excellent at coding, fast at shipping, self-directed, comfortable using modern AI tools, and excited to work across product, data, infrastructure, and automation.
Bonus points for experience in power engineering, renewables, grid infrastructure, geospatial data, scraping, document AI, or large-scale data pipelines.
High ownership, very little bureaucracy, and real impact on renewable energy deployment.

We're hiring a Trust & Safety Engineer to join Runway's AI Safety and Responsibility team. Runway builds AI world models - general-purpose simulators for robotics, science, and storytelling — and this role exists to keep that safe as it reaches millions of users.
Stack: TypeScript API on ECS/Fargate, Python/PyTorch inference backend, Claude + Gemini for safety/moderation, ClickHouse for abuse signal detection, AWS + GCP, Terraform, Prometheus/Grafana.
It's a generalist role, hands-on across the full engineering lifecycle - from model pre-training through productionisation. We're looking for 3+ years production Python or TypeScript, comfort across the stack, and experience with data pipelines (ClickHouse a plus).
Apply here: https://jobs.ashbyhq.com/runway-ml/c3ebd871-ea78-4b71-80a2-7..., or feel free to reach out with any questions (info in bio).

Tower is a Python-native serverless data platform. Data teams write plain Python, and we handle packaging, dependency resolution, scheduling, and execution across a serverless runtime built on Apache Iceberg. There's no clusters to manage, no YAML to write, no pipelines to rewrite to fit someone else's engine. If you've ever wanted your local Python script to just run in production at scale without a Databricks detour, that's the product.
We're a small, senior team split between London and Berlin. We've built a lot of tech: Custom run dispatch service, multi-region routing, storage based on Apache Iceberg, and the runtime itself, to name a few. This is deep systems work--things like scheduling, distributed execution, and performance. We're not gluing SaaS together.
Stack: Go and Rust for the platform, Python everywhere it matters, Kubernetes (EKS + Karpenter) on AWS, RDS Postgres, ElastiCache Redis, S3/Iceberg, WorkOS for auth.
Looking for:
* strong distributed-systems fundamentals
* comfort owning a system end to end
* taste for correctness under load
Bonus: data-platform, query-engine, or Iceberg experience; async Rust; Kubernetes internals.

Recycleye and CP Group build recycling plants, and are forming a new team to provide data analytics and optimisation to recycling facility operators. There are optical sorters, AI powered airjets, AI robots and many different types of machines in a waste facility. The waste is constantly varying and the plant can be configured in thousands of ways to sort the material. This team will be collecting this data using different sensors and cameras.
We're looking for a data scientist with experience in deep analytics and statistical modelling to understand and visualise the data, and then and model the plant to spot issues before they impact operations, and identify optimistions that make a real difference. We use Clickhouse and Python or Go.
Any questions, feel free to email me at peter.fine@recycleye.com

ABOUT FRACTILE Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the amount of time they take to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts.
We’ve recently raised $220M from Founders Fund and Accel and the most important work lies ahead. Come and join the mission!
THE ROLE As a Software Engineer you will be a core part of our technical team working alongside the hardware, software and research teams to solve cutting-edge problems in AI hardware, ranging from verification to simulation, alongside the best of the best (DeepMind, Apple, Meta…).
ABOUT YOU 1) You have exceptional ability. We look for pivotal IC contributions that solved the hardest problems in big tech companies or hedge funds; competitive hackathons, International Olympiad medals, or rank highly in other competitions like advent of code
2. You are a top engineer. We are not looking for specific languages or technologies - you will be a master of several, you excel at algorithmic skills and solving problems logically in any programming language. And you are very comfortable learning new skills on the fly. You like to work in Python and C++
3. It’s likely you have several years of professional experience, but we will make exceptions for the right candidate
4. You want to work with the best. And you are excited to work in chips, solving the hardest problems at the frontier of AI
WHAT WE OFFER 1. Competitive compensation and meaningful equity 2. A very cool office with London's best views 3. Private medical insurance and pension benefits
