secret | REMOTE | Contract to full time | Any country

I need an experienced Unity graphics specialist to reboot a beloved and unique simulation game IP as part of a small dedicated team. You are comfortable writing terrain, foliage, atmospherics, volumetrics, particle system from scratch, along with more typical URP/SRP dark arts + fell workings. You are OK with an opinionated codebase that largely sidesteps standard Unity stuff.

Mentimeter | Engineering Director | Stockholm, Sweden | ONSITE (hybrid, 3 days/week in office) | Full-time

Mentimeter turns presentations into conversations – live polls, quizzes and Q&A that get every voice in the room heard. Product-led, 300M+ people have used it, and we are going multi-product.

I am the CTO. I am hiring an Engineering Director – one of two, reporting to me. The ask is big. We are making the agentic development lifecycle the one way we build – SDLC is out, ADLC is in. I want a partner to work out with me what an engineering org is when AI writes most of the code. Nobody has that playbook, yet. We get to co-author it, and help set patterns others copy.

The shape: 5–7 teams, 30–40 engineers, led through Engineering Managers and Staff Engineers. You own technical direction, architecture and the engineering-quality bar, and co-own outcomes with Product and Design. You were an excellent engineer before you were a leader.

Practical: Stockholm HQ, 3 days/week in office. Daily work is in English (50+ nationalities). No visa relocation sponsorship for this role.

Tower (tower.dev) | Senior Backend / Platform Engineer | London or Berlin | HYBRID | Full-time

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.
