Research Scientist, Interpretability
Join the team working to understand what our models are actually doing — the circuits, features, and mechanisms behind their behavior. Your work will feed directly into the safety evaluations we publish before every release.
What you'll do
- Design and run experiments on internal representations of Krus, Mantus, and Corus
- Build tools that let other researchers and reviewers inspect model behavior
- Publish findings openly and write for both research and general audiences
- Work with the evaluations team to turn interpretability findings into testable commitments
What we're looking for
- A track record of rigorous research in machine learning, preferably on interpretability or related areas
- Comfort with large-scale experiment tooling and analysis
- A belief that interpretability work matters most when it changes what gets deployed
This role would report to Lucas Ferrand, Head of Research.
Research Scientist, Alignment
Help us make Ichnus genuinely helpful, honest, and honest about its limits. This is applied alignment work — the methods we develop go into production models used by millions of people.
What you'll do
- Develop and test training and post-training methods that improve helpfulness and honesty
- Study when models overstate their confidence, and build methods that reduce it
- Contribute to the "deference under uncertainty" research line and its product behavior
- Collaborate with the evaluations team to measure alignment improvements
What we're looking for
- Strong background in deep learning and practical alignment or RLHF-style work
- Experience shipping model behavior changes into a production product
- Comfort moving between research questions and product constraints
This role would report to Priya Raman, Head of Alignment.
Research Engineer, Evaluations
Build the infrastructure that tests every Ichnus model before it reaches people — capability benchmarks, safety evals, and adversarial red-teaming at scale.
What you'll do
- Own the evaluation harness that gates model releases
- Design new evals where existing ones are not good enough, including public-facing safety evals
- Run and analyze red-teaming campaigns with internal and external reviewers
- Publish evaluation results and methodology openly
What we're looking for
- Strong engineering skills in Python and distributed evaluation tooling
- Experience with LLM evaluation or a related testing-heavy discipline
- Comfort with adversarial thinking and a low tolerance for "good enough"
This role would report to Tomás Herrera, Head of Evaluations.
Senior Machine Learning Engineer, Serving
Keep Ichnus fast, reliable, and affordable for everyone. Your systems are what make "free by default" economically possible at scale.
What you'll do
- Build and operate the serving stack behind Krus, Mantus, and Corus
- Work on routing, quantization, and tiered compute allocation
- Keep latency and reliability targets while controlling cost
- Pair with the efficiency research team to ship new methods to production
What we're looking for
- Deep experience with production ML serving systems (inference engines, GPU clusters)
- Strong systems engineering fundamentals
- Comfort with on-call for critical infrastructure
This role would report to Hana Sato, Engineering Lead.
Machine Learning Engineer, Training Infrastructure
Own the training runs behind every model we release — from data pipelines to distributed training to the tooling that makes runs reproducible.
What you'll do
- Build and maintain distributed training infrastructure
- Own data pipelines for pre-training and post-training data
- Instrument runs so researchers can move fast without breaking things
- Document everything so future runs are easier than the last
What we're looking for
- Experience running large-scale ML training workloads
- Strong systems programming and Python skills
- A love of boring, reliable infrastructure
This role would report to Hana Sato, Engineering Lead.
Applied AI Engineer, Product
Turn research and model behavior into the Ichnus people actually use — the assistant, its apps, and the experiences that make it feel like something you can trust.
What you'll do
- Build and maintain the Ichnus apps and their interaction design
- Prototype features that surface model capability and limits honestly
- Work with the community team to incorporate user feedback into the product
- Keep quality high: we would rather ship less than ship something we cannot stand behind
What we're looking for
- Strong product engineering experience (web and mobile)
- Design sensibility and attention to detail
- Experience building with LLMs a plus, a willingness to learn a must
This role would report to Hana Sato, Engineering Lead.
Policy Researcher, AI Governance
Study how AI should be governed — and help Curos live up to the standards we argue for. Your work spans research papers and the internal charters we are held to.
What you'll do
- Research questions of accountability, transparency, and public benefit in AI
- Draft and maintain Curos's governance documents and release commitments
- Liaise with the board and oversight committees
- Publish policy research openly and in plain language
What we're looking for
- A research or practitioner background in AI policy, governance, or law
- Strong writing, including for non-expert audiences
- Comfort with the tension between ideals and operational reality
This role would report to Grace Adeyemi, Director of Policy & Governance.
Program Lead, Community & Funding
Run the two relationships that keep Curos independent: the community that uses Ichnus, and the donors and foundations that fund it. You will own our community council and our public funding reports.
What you'll do
- Run the community council — elections, meetings, and follow-through
- Manage grant applications and relationships with foundations
- Maintain and publish the transparency reports with the ops team
- Run community events, from office hours to public red-teaming sessions
What we're looking for
- Excellent project management and stakeholder communication
- Experience with community programs or grant work
- A comfort with the public nature of our commitments
This role would report to Sam Whitfield, Head of Operations.
Operations & Finance Manager
Keep the finances boring and transparent. You own budgeting, accounting, and the numbers that make our transparency reports possible.
What you'll do
- Own budgeting, forecasting, and spend tracking
- Manage the annual audit and financial reporting
- Build the numbers behind the transparency page
- Keep costs lean without cutting into mission-critical work
What we're looking for
- Strong finance and accounting skills (non-profit experience a plus)
- Meticulous, honest, and comfortable with public scrutiny of the numbers
- Enthusiasm for boring, correct finance
This role would report to Sam Whitfield, Head of Operations.
How we hire
No take-home that takes a weekend. No whiteboard trivia. The process is a conversation, a short paid exercise, and a chance to talk with the team you'd join. We care most about whether you can do the work and believe in the mission.
We pay a fair, transparent salary band for every role — no negotiation roulette, no equity, because there is no equity to give. Health care, retirement, and generous leave are standard.
We are not currently hiring. Curos is a concept project, and these listings are fiction. If you love the idea of non-profit AI, we hope you'll build it — or join a real organization working on it.
