Member of Technical Staff — Environments / Evals

Remanence; Paris (TX); Hybrid; USD 102,000 - 147,000; Full time

Benefits offered by this job

Visa sponsorship

Relocation support

Hybrid work

Job summary

Remanence is building the next era of enterprise AI with high-fidelity simulations and adaptive curricula to train and evaluate agents in realistic environments. You will help design reproducible systems and evaluators that ensure learning transfers to real deployments.

The team prioritizes first principles, experimentation, and rapid iteration, aiming to deliver scalable, safe, and reliable AI training loops across complex workflows.

Qualifications

• Strong engineering fundamentals with experimental judgment.
• Curiosity about model behavior and real-world deployment.
• Experience with synthetic data, world models, agents, curriculum learning, or evaluation is valuable.

Responsibilities

• Build pipelines that generate tasks, initial states, tool configurations, and verifiers; filter for validity, diversity, and difficulty.
• Develop curriculum strategies that select and generate tasks based on model failures, learning progress, and gaps in capability coverage.
• Train learned simulators from deployment traces to model user behavior, tool responses, and environment dynamics; validate fidelity.
• Build reproducible evaluation harnesses and held-out tests that detect reward exploitation, simulator shortcuts, contamination, and failures to generalize.

Job description

Member of Technical Staff — Environments / Evals

Remanence is pioneering the next era of enterprise AI by building intelligent systems that learn continuously from real-world execution. We transform complex enterprise workflows and business context into dynamic, interactive environments where AI agents can safely learn, adapt, and improve. By combining high-fidelity simulation environments with state-of-the-art training loops, we build specialized models that solve long-horizon, complex tasks with unmatched reliability. We’re building the most talent-dense AI team in Europe to make this happen.

You’ll build systems that automatically synthesize tasks, construct adaptive curricula, and learn simulators of real-world deployments. Your goal is to create a continually improving source of training experience, alongside evaluations that establish whether learning transfers to real use.

What you’ll work on

• Build pipelines that generate tasks, initial states, tool configurations, and verifiers; automatically filter for validity, diversity, and difficulty.
• Develop curriculum strategies that select and generate tasks based on model failures, learning progress, and gaps in capability coverage.
• Train learned simulators from deployment traces to model user behavior, tool responses, and environment dynamics. Validate their fidelity against real interactions.
• Build reproducible evaluation harnesses and held-out tests that detect reward exploitation, simulator shortcuts, contamination, and failures to generalize.

Relevant technologies

• ML Frameworks: PyTorch, transformers, and vLLM or SGLang.
• Environment execution: Ray, Docker, OpenEnv and Gymnasium-style interfaces; Playwright for browser-based tasks.
• Evaluation and data: Inspect AI and DeepEval for evaluations and custom verifiers/graders, versioned datasets with Apache Parquet, LanceDB and DVC.

About you

You combine strong engineering with experimental judgment and curiosity about model behavior. You think from first principles about what the company needs, not just the task in front of you. Experience with synthetic data, world models, agents, curriculum learning, or evaluation is valuable.

We welcome both deep specialists and generalists who master unfamiliar domains exceptionally quickly. You don’t need prior experience across the entire stack.

What we offer

• Competitive compensation and equity.
• A fast-paced environment combining frontier research with impactful real-world applications.
• Visa sponsorship and relocation support for candidates joining us in Paris or London.
• A flexible hybrid setup, with a preference for working together in person.
