valència, España Friday Systems A tiempo completo

Friday Systems builds AI that allows industrial robots to adapt to dynamic warehouse environments. We focus on high-throughput palletizing and related tasks where classical approaches break down. Our stack is built around Deep Reinforcement Learning with modern sequence models. Tiny team, zero bureaucracy, direct impact, salary + equity. THE ROLE Own the DRL stack end-to-end : formulation → algorithm design → large-scale training → evaluation → deployment. You’ll work directly with the CTO to turn cutting-edge DRL into production throughput at customer sites. YOU WILL Design & ship DRL algorithms (PPO / SAC / DDQN and variants, based on encoders / cross-attention / pointer networks) for complex control & combinatorial optimization. Tackle stability & sample-efficiency : GAE, normalization, entropy / KL control, distributional / value-loss tuning, curriculum learning and reward shaping, … Launch multi-GPU training, parallel rollouts, efficient replay / storage, and reproducible experiment tooling. Collaborate with the C-Level Team to ensure product excellence and alignment with business strategy. Forge strong relationships with clients, effectively translating their needs into unique technology solutions. Build and nurture a high-performing team by attracting top talent. Provide mentorship and leadership to foster a culture of quality and innovation. YOU HAVE Track record shipping RL beyond academic demos : you’ve led at least one end-to-end RL system from idea to production or a state-of-the-art benchmark in the last 3–5 years. Extensive Deep Learning, Reinforcement Learning & PyTorch expertise : You can implement several DRL algorithms from scratch, reason about root-cause performance drops and make informed decisions about next steps. Systems know-how : Python, Linux, Docker, Multi-GPU, Cloud (AWS). Math maturity : MDPs / Bellman operators, policy gradients, trust-region / KL, GAE / λ-returns, stability / regularization in on-policy vs off-policy regimes. Ownership : you’re comfortable being the primary owner for experiments, code quality, and results in a small team. Location / time zone : EU-based (CET±1) and able to travel occasionally to customer warehouses. We are not considering entry-level or coursework-only profiles for this role. HIRING PROCESS Deep technical session with CTO on your past RL work (no LeetCode, no homework) Two one-hour “Traits & Skills” conversations with our other Co-founders.
