Senior Software Engineer I

About the Role

As a Senior Software Engineer on the CoCounsel Applications team, you will play a hands-on role in building and evolving our external integration strategy leveraging MCP and A2A. You'll design and deliver full-stack features across our frontend and backend systems, write high-quality code every day, and work closely with product, design, and platform partners to ship high-impact, customer-facing features.

• 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.
• Deliver Quality Software: Apply best practices for code quality, performance, accessibility, testing, and maintainability in your own work, and contribute to raising the bar through thoughtful code reviews.
• Collaborate Cross-Functionally: Partner closely with product, design, and backend teams to clarify requirements, help define APIs, and deliver cohesive user experiences.
• Own Your Workstreams: Break down features into well-scoped tasks, provide reliable estimates, and take your work from development through production with minimal oversight.
• Share Knowledge: Contribute to a strong engineering culture through pairing, code reviews, and open technical discussion with your teammates.
