[Remote] Full Stack Product Engineer

Note: The job is a remote job and is open to candidates in USA. LTS is seeking a Full-Stack Product Engineer to join a small, senior engineering team applying frontier AI to modernize a legacy codebase. The role involves end-to-end feature delivery, building frontend in React, and integrating AI tooling into product surfaces while ensuring product quality and user trust.

Responsibilities

• End-to-end feature delivery across the product — code understanding, code translation, modernization authoring, review surfaces
• Build the frontend in modern React with a serverless TypeScript backend
• Pair tightly with the Principal Designer in code — Designer absorbs visual-heavy surfaces, the Full-Stack Engineer owns logic-heavy surfaces (authoring, review, agent integration)
• Write specs, ship, watch usage, iterate; close the loop from design through deploy
• Push back on a spec you think is wrong before writing the code
• Own the product-quality bar across the surfaces you ship — performance, accessibility, polish, and the moment-to-moment feel
• Integrate agent output into product surfaces in a way that respects both engineering correctness and user trust

Skills

• Bachelor's degree in Computer Science, Engineering, or a related field, plus 5 years of professional full-stack engineering experience; equivalent experience may substitute for the degree requirement
• Track record of shipped product features that can be walked through in detail — including how the design changed once real users got their hands on it
• Ability to work in a fast-paced, collaborative environment
• Senior full-stack engineer; both frontend and backend are part of the daily job
• Modern React (hooks, suspense, recent patterns); strong TypeScript fluency
• Comfort across a serverless cloud backend: typed RPC, ORM-level work, AWS or comparable
• Density of shipped work — recent product features that real users used, with measurable iteration after launch
• Pushes back on a spec when wrong; doesn't wait for permission to ship
• Heavy native use of AI tooling: subagents, model as collaborator
• Demonstrated experience in a remote work environment
• Prior developer-facing or technical-user-facing products (IDEs, observability tools, internal platforms)
• Experience visualizing complex graphs or code relationships (call graphs, dependency trees, AST views)
• Design sense good enough to ship polished UI without a designer on everyday work
• Experience pairing with a designer directly in code rather than via Figma handoff
• Public open-source work or shipped side projects with visible craft

Benefits

• The opportunity to support high visibility federal missions in IT and healthcare
• A culture that values innovation, growth, collaboration, and quality
• Access to cutting-edge tools and technologies
• Comprehensive benefits for you and your family
• A career path that rewards ambition and performance
• LTS shares salary ranges to promote transparency. Compensation ranges are provided for informational purposes, and final compensation may vary based on experience, skills, location, and role requirements.
• LTS is committed to offering eligible employees comprehensive benefits that will provide them with options intended to meet their needs and the needs of their family.
