Machine Learning Engineer - Forecasting & Scheduling

Great customer support requires human agents and AI in perfect balance, and Assembled is the only unified platform that orchestrates both at scale. Companies like Canva, Etsy, and Robinhood use Assembled to coordinate their entire support operation — in-house agents, BPOs, and AI — in a single operating system. With AI Agents that resolve cases end-to-end, AI Copilot for agent assistance, and AI-powered workforce management that optimizes both human and AI capacity, Assembled helps teams deliver faster, better service while making smarter decisions about how to staff and automate. Backed by $70M from NEA, Emergence Capital, and Stripe, we're building the platform that makes AI and human collaboration actually work.

• Contact-volume forecasting: data pipelines, statistical/ML models and inference services that predict ticket volumes, agent demand and time to resolution.

• Queueing simulation: realistic models of synchronous (phone, chat) and asynchronous (email, messaging) queues that forecast wait times, staffing demand considering clearing weekend backlogs while still receiving new tickets.

• Scheduling tooling: a calendar-like UI that lets managers create and adjust rosters for thousands of agents while respecting preferences, labor laws and SLAs.

• Agent empowerment: self-service pages for shift swaps, time-off requests and overtime management.

• Lead the architecture and delivery of new ML features end-to-end: research → prototype → production.

• Drive technical roadmaps, code reviews and design sessions to share your knowledge with the rest of the team.

• Mentor engineers, unblock thorny problems and act as subject-matter expert for data science topics.

• Collaborate with Product and Design to turn unclear customer problems into shippable solutions.

• 5+ years shipping production time-series forecasts or similar ML systems.

• Proficient in a typed backend language (Go, Java or Rust) and comfortable with Python for research.

• Prior work on large-scale scheduling or optimization problems (e.g. nurse-rostering).
