Alignerr, Labelbox's human data organization, is seeking a Forward Deployed Research Scientist to join their team. This role sits at the intersection of research science and client delivery, embedding research capability directly into client engagements. Unlike traditional research roles, you will work on multiple client projects simultaneously, operating on short timescales of days to weeks. You will engage with research teams at major AI labs, reason scientifically about data strategy in real time, fine-tune open-weight models to validate data methodology, and collaborate with the Applied Research team on publications. This fast-paced, applied role offers clear ownership and autonomy, with career growth directly tied to your contributions.

Thinking Machines is seeking a Site Reliability Engineer (SRE) to ensure the speed, reliability, and ease of iteration for our post-training and reinforcement learning (RL) systems. This role is akin to production engineering or site reliability, focused on model training infrastructure. You will be responsible for the health of training runs, clusters, and pipelines, working closely with research teams to debug issues in real-time, strengthen infrastructure, and develop tools and automation that allow researchers to focus on scientific discovery rather than job management. This position offers significant ownership, requiring you to be the point person for critical issues during active model runs and to implement solutions preventing future occurrences.
