Forward Deployed Engineer

Manifest OS is the leading AI-native company on a mission to replace the billable hour and make legal services more accessible for American businesses and consumers. We power the next generation of AI-native law firms with one unified global brand, a proprietary technology platform, and a centralized back office - enabling lawyers to eliminate the administrative burden and focus on delivering exceptional outcomes for their clients.

Manifest OS has raised a $60M Series A from Menlo Ventures, Kleiner Perkins, First Round, and Quiet Capital.

This role sits at the intersection of engineering and customer success - you'll build custom solutions for Manifest's largest customers and present them directly to stakeholders. You're the engineer in the room who can speak fluently about the product while also shipping it. Success is measured by expansions and renewals, not sprint velocity.

• Build custom software solutions tailored to individual enterprise customer needs

• Present solutions directly to customers and prospects, including at conferences

• Scope and respond to RFPs, owning the technical narrative end to end

• Partner with Sales, CS, and Account Management to close and expand deals

• Identify when to build custom versus accelerate a core product initiative

• Translate customer pain points into scoped, buildable product specs

• 3+ years of software engineering experience

• Experience delivering production-grade customer solutions that require structured execution, testing/validation, and iteration

• Confident leading customer conversations, demos, and presentations

• Ability to communicate clearly with senior technical stakeholders, translate requirements into implementation plans, and drive delivery

• Experience in a commercial or sales-adjacent engineering role

• Ability to scope technical solutions quickly under deal timelines

• Have relevant experience in a technical customer-facing role (e.g., solutions engineering, forward-deployed engineering, technical consulting, implementation engineering, technical product/PM, or similar).

• Experience building with or around LLMs / AI agents (prompting, evaluation, guardrails, tooling, workflow design, etc.)

You want your engineering work to directly drive revenue and customer outcomes. You thrive when presenting and explaining technical work to non-technical audiences. You enjoy switching between building, scoping, and customer-facing work.

You prefer deep, heads-down core product engineering over customer interaction. You want clear separation between engineering and commercial responsibilities. Ambiguous, fast-moving deal cycles feel draining rather than energizing.
