Senior AI Engineer

**Who we are** Active is Built to Accelerate—a category-defining Agentic Intelligence Native Services (AINS) company that equips the teams closest to the work, accelerates business outcomes and builds advantage that compounds. We’ve been named one of the 2026 Inc. 5000’s Top 40 fastest-growing companies in AI & Data and 723 overall in the US. Expert humans lead. Powerful agents extend what we can accomplish. We scale for velocity, not vanity—and that starts with our people. We expect exceptional judgment, uncompromised excellence and uncommon speed. Think independently. Challenge assumptions. Act decisively. Own the result, not just your assignment. Work without ego, and never confuse activity with impact. In return, you get meaningful ownership, a voice that can change the direction, direct access to proven leaders and the freedom to build—not simply execute someone else’s instructions. We put decision-making power close to the work and back it with context, trust and clear accountability. Your scope can expand as fast as you demonstrate the ability to carry it; your trajectory is driven by contribution, not tenure or organizational politics. High-potential talent is welcome. Bring intellectual horsepower, relentless curiosity, pride in your craft and the ambition to take on work bigger than your current title. You do not need to arrive with every answer. You do need to learn fast, seek feedback, honor commitments and make the people around you better. Our agentic teammates amplify that capability; they do not replace your judgment or excuse a lower standard. This is not a place to coast on a résumé, protect a title or rest and vest. It is a place to do consequential work, earn extraordinary responsibility and grow alongside people who expect as much of themselves as they do of you. **Human-led. AI-powered. Precision-built.** **The bar is high. There is no ceiling.** **Who you are** As a Senior AI Engineer at Active, you are the technical lead of a team embedded with the client, and you own the production outcome: what gets built, how it runs inside the client’s environment, and whether it is still running well after we step back. In a single week you might settle an architecture question with your engineers, walk a client’s security team through the evidence for an agent’s permissions, write the hardest part of the system yourself, and tell an executive what the first release will and will not do. The decisions are yours. You choose where model reasoning earns its cost and where deterministic software should do the job, and you answer for that choice in production. What one engagement teaches you becomes reusable components that every later team inherits, so your work shapes how Active builds as well as what one client gets. The engineers who thrive here have led production systems end to end and have spent enough time with customers to know that the hard part is rarely the model. *We are looking for someone to do the following:* * Lead the technical delivery of an engagement end to end, from the first working session with the client through day one of operation and handover * Turn a named business outcome into an architecture across four layers (operating model, execution, intelligence and interface), choosing the right mix of agentic reasoning, deterministic execution and human decision * Design and build agentic systems for production: orchestration, tool use, context and memory management, model routing, and multi-agent coordination where the work warrants it * Engineer governed execution in from the start: least-privilege access, autonomy and approval thresholds, exception handling, stop controls, rollback and recovery * Establish the evaluation practice for the engagement, so that model, prompt and tool changes are tested against real client cases before they reach production and monitored afterward * Integrate with the enterprise systems the client already runs, sequencing cutovers around business continuity and keeping ownership of each interface explicit * Own the economics of what you build: cost per completed workflow, including inference, infrastructure, human review, exceptions and recovery * Represent the engineering in client security, architecture and risk reviews, and bring the evidence those reviews need * Work with consultants to scope the outcome, baseline and acceptance criteria, and push back when scope is unclear or an approach will not hold up in production * Lead and mentor the engineers on your team, and set the standard for code review, testing, documentation and the use of AI coding agents * Codify reusable patterns, connections and controls into Active’s shared foundation, and assess what new risk the next use case introduces before reusing them * Hand over a system the client’s engineers can operate, inspect and extend, with the documentation, access and operating knowledge to do it * Join early practitioner conversations with prospective clients to assess technical fit and shape the first outcome *What you will need to be successful* * Bachelor’s degree in computer science, software engineering or a related field and 5+ years of professional software development experience, or 10+ years of experience in lieu of a degree * Strong programming skills in Python and at least one of Java or TypeScript, with production systems you led from design through release * Production experience with LLM-based systems, including agent development, tool integration and evaluation * Experience in a customer-facing technical role, such as professional services or solutions engineering, or as a technical founder * High agency: you operate without close direction and find a way through the ambiguity of complex organizations * Ability to explain architecture, tradeoffs and risk to executives and to non-technical operators * Willingness to travel to client sites as engagements require *Additional preferred qualifications* * Experience with data pipelines, data modeling and data warehouse design * Depth in cloud platforms (AWS, Azure or GCP), containerization and CI/CD * Working command of security and governance fundamentals: identity and access management, audit logging and data privacy * Experience delivering in regulated industries, including familiarity with FHIR and healthcare interoperability standards * Experience with MCP servers, agent skills and multi-agent orchestration * Experience building shared platforms or reusable components used by more than one team **Closing** * Not every strong candidate will match every line above.
