ABOUT US:

At Lang Chain, our mission is to make intelligent agents ubiquitous. We build the foundation for agent engineering in the real world, helping developers move from prototypes to production-ready AI agents that teams can rely on. We began as widely adopted open-source tools and have grown to also offer a platform for building, evaluating, deploying, and operating agents at scale.

Today, Lang Chain, Lang Graph, Lang Smith, and Agent Builder are used by teams shipping real AI products across startups and large enterprises. Millions of developers trust Lang Chain to power AI teams at companies like Replit, Clay, Coinbase, Workday, Lyft, Cloudflare, Harvey, Rippling, Vanta, and 35% of the Fortune 500.

With $125M raised at Series B from IVP, Sequoia, Benchmark, CapitalG, and Sapphire Ventures, we're at a stage where we're continuing to develop new products, growth is accelerating, and all team members have meaningful impact on what we build and how we work together. Lang Chain is a place where your contributions can shape how this technology shows up in the real world.

ABOUT THE TEAM:

The Professional Services team is the bridge between Lang Chain's technology and the enterprise customers building on top of it. We partner with some of the world's most ambitious companies to help them move from pilot to production — designing solutions, accelerating time-to-value, and ensuring teams get the most out of Lang Chain, Lang Graph, and Lang Smith. We work at the intersection of deep technical expertise and customer partnership, and we take pride in the outcomes our customers achieve. As Lang Chain grows, PS plays a direct role in shaping how enterprise AI gets built in the real world.

ABOUT THE ROLE:

We're looking for an Engagement Manager to join our Professional Services team. You'll manage multiple concurrent technical engagements, ensuring successful delivery of Professional Services projects for enterprise customers. You'll be the primary point of contact for customers and coordinate cross-functional teams to deliver exceptional outcomes.

This role offers direct impact on customer success, the opportunity to shape processes and methodologies, and the chance to work with cutting-edge AI technology. You'll join a collaborative team environment with a strong engineering culture.

Location: This role can be based in our San Francisco or New York office. Employees within commuting distance work from the office five days per week. Candidates who live outside commuting distance (e.g. >1hr each way) may be eligible for hybrid arrangements depending on location and role requirements. Open to remote candidates within the US.

WHAT YOU'LL DO:

• Engagement Lifecycle Management: Manage the full engagement lifecycle from SOW review through closeout, including planning, execution, risk management, scope management, and handoff

• Customer Communication & Relationship Management: Serve as the primary point of contact for customers — deliver status updates, manage expectations, handle escalations, and negotiate scope changes

• Multi-Engagement Management: Manage 5–8 concurrent technical engagements simultaneously while maintaining quality and meeting deadlines

• Cross-Functional Coordination: Coordinate with Solution Architects, AI Engineers, Sales, Support, Enablement, and Product/Engineering teams; manage resource allocation and capacity planning

• Risk & Issue Management: Proactively identify risks and issues, develop mitigation strategies, track resolution, and ensure deliverables meet quality standards

WHAT YOU'LL BRING:

• You have 5+ years of engagement or project management experience, preferably with technical or software engagements

• You've managed multiple concurrent engagements and know how to keep quality high across all of them

• You have strong experience working with enterprise customers and leading customer-facing communication

• You've coordinated cross-functional technical teams — engineers, architects, product — and managed resource allocation

• You're experienced with project management tools such as Linear, Jira, Asana, or similar

• You've handled scope change management and complex stakeholder dynamics

• You have start-up DNA: you thrive in fast-paced, ambiguous environments and don't wait to be told what to do

• You're a natural communicator — clear, direct, and effective with both technical teams and executive stakeholders

You exemplify our operating principles

• You are motivated to build something great: you hold a high bar for quality, craft, and impact

• You embrace hot takes: you share informed opinions, challenge the status quo, and engage in constructive debate

• You operate with maximum agency: you take ownership, move work forward independently, and help others unblock

• You run to the roar: you lean into hard problems, ambiguity, and fast-moving challenges

NICE TO HAVE:

• PMP or similar project management certification

• Experience in Professional Services or consulting

• Experience with AI/ML or infrastructure engagements

• Experience with time tracking and billing coordination

• Knowledge of software development lifecycle and agile methodologies
