Job description

We're looking for a Lead Engineer to join the CoCounsel Application Experience team and play a hands‑on technical leadership role in building and evolving our core product experiences. In this role, you'll own and deliver full‑stack solutions across our frontend and backend systems, lead by example in code, and work closely with product, design, and platform partners to deliver high‑impact, customer‑facing features.

About the Role

• Build End-to-End Solutions: Design and implement full-stack features across frontend and backend systems, including hands‑on development in our React, TypeScript, and Python stacks - and direct contribution to AI-powered capabilities such as agentic workflows, LLM integrations, and MCP-based tooling.
• Set Technical Standards: Establish and uphold best practices for code quality, performance, accessibility, testing, and maintainability, leading by example through reviews and contributions.
• Collaborate Cross-Functionally: Partner closely with product, design, and engineering teams to shape requirements, define APIs, and deliver cohesive user experiences.
• Drive Execution: Break down complex initiatives, provide reliable estimates, and help the team deliver work from development through production.
• Mentor Engineers: Support the growth of other engineers through pairing, code reviews, and ongoing technical guidance.

About You

You're a fit for the role of Lead Engineer if your background includes:

• Technical Experience: 6+ years of professional software engineering experience building and shipping production web applications used by real customers, with active, hands‑on coding contributions in the last 2‑3 years.
• Frontend Expertise: Strong experience with modern frontend frameworks such as React, along with a solid understanding of TypeScript and frontend architecture.
• Backend Skills & AI Skills: Hands‑on experience building APIs and services with Python as a core language, working knowledge of Node.js, and working familiarity with GenAI concepts including prompt engineering, agentic system design, LLM orchestration frameworks, and Model Context Protocol (MCP).
• Technical Leadership: Proven ability to lead through influence rather than authority, improving systems, reducing technical debt, and guiding architectural decisions.
• Collaboration & Communication: Comfortable operating in fast‑paced, ambiguous environments, with strong communication skills and a collaborative mindset.

Preferred Qualifications

• BA or BS in Computer Science or equivalent practical experience.
• Experience with performance optimization for web applications, including monitoring, profiling, and tuning for scale.
• Hands‑on experience building AI‑powered product features, including working with LLM APIs, RAG pipelines, or agentic workflows in a production environment.
• Familiarity with AI/ML infrastructure including vector databases, model serving, and cost/latency optimization for LLM‑powered features.
