Applied AI Engineer

• We’re growing our Applied AI team to dramatically increase productivity across Engineering, Sales, Support, and Operations, and to ship AI-powered products that customers rely on directly
• As an Applied AI Engineer, you’ll design and ship production AI systems that change how WorkOS builds, sells, supports, and scales. You’ll also be building things that WorkOS customers use, and systems that the entire company depends on daily
• You’ll work on a small, high-ownership team that:
• Chooses problems based on measurable impact
• Moves from idea → prototype → production in days or weeks
• Ships at both layers: internal leverage and customer-facing product
• Adapts quickly as models, tools, and best practices evolve
• This is a 0→1 role with company-wide visibility
• Design and ship customer-facing AI products like ask.workos.com, AI support bots embedded in customer Slack channels, and new surfaces we haven’t built yet
• Build internal tools that become part of people’s daily work: agents, automations, and workflows that are stable, observable, and easy to maintain
• Work on big bets: a unified bot framework, a sandboxed coding harness agent, and infrastructure that lets the entire company ship
• Use LLMs, embeddings, retrieval, and tool-calling to plug into docs, Slack, GitHub, CRM, analytics, support systems, and internal services
• Replace repetitive, multi-step manual processes with orchestrated, AI-driven flows that span multiple apps and data sources
• Stay current on new models and tooling, run focused experiments, and help the team converge on patterns, libraries, and infrastructure that compound over time
• Example problems you might work on:
• A sandboxed coding harness that can safely take a bug report or feature spec all the way to a deployed change
• A unified bot framework that powers every AI touchpoint, internal and customer-facing from a single, observable backbone
• A GTM intelligence layer that gives reps live account context, meeting prep, and follow-up from CRM, product usage, and conversation history
• Turning noisy, cross-tool workflows (tickets, Slack threads, docs) into a single agent that handles triage, routing, and suggested actions
• Infrastructure that lets any WorkOS team ship a reliable internal AI app without reinventing the stack

Benefits

• WorkOS pays 90% of premiums for employees and dependents to help keep your family healthy

• WorkOS provides a 3% match of your 401k contributions to help you save for retirement

• Relax and recharge with 20 days of paid yearly vacation. We also offer 12 weeks of parental leave for new parents

• Monthly stipend for gyms, yoga classes, race registrations, or whatever keeps you active

• Monthly stipend for a massage, meditation class, therapy, or activities that enhance your mental well-being

• Outfit your working space with a stipend for equipment that will keep you comfortable and productive

• You’ve taken AI-powered systems from idea to production and through at least one iteration cycle with real users

• You think about failure modes, observability, and ownership, not just whether the demo works

• Comfort with ambiguity and fast change. The problem, the tools, and the “right” patterns are all evolving, you’re excited to help define them

• Strong engineering fundamentals. You’re comfortable owning services, data flows, and integrations end-to-end

• Bias toward action. You care less about the model and more about removing real bottlenecks, saving hours, or unlocking workflows the company couldn’t do before

• Experience building with LLM APIs

• Prior work on customer-facing AI products

• Exposure to MCP or similar protocols for connecting AI agents to real systems

• Experience with embeddings, retrieval/RAG architectures, and structured tool-calling or agents
