Job Description
We’re looking for a Lead Engineer to join the CoCounsel Applications team and play a hands-on technical leadership role in building and evolving our external integration strategy leveraging MCP and A2A . 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:
As a Lead Engineer, you will:
- 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/A2A-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 backend 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: Some experience with modern frontend frameworks such as React, along with a solid understanding of TypeScript and frontend architecture
- Backend Skills & AI Skills: Strong experience building APIs and services with Python as a core language, and working familiarity with GenAI concepts including prompt engineering, agentic system design, LLM orchestration frameworks, and some familiarity with MCP/A2A
- 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
