Senior Full-Stack Software Engineer

DealerCopilot is an early-stage AI company focused on enhancing dealership operations through technology. They are seeking a Senior Full-Stack Software Engineer to take ownership of feature development across the full stack, collaborating closely with the technical co-founder and leading engineering standards.

Responsibilities:

• Own end-to-end feature development across our full stack: React frontends, C#/.NET and Python backends, and AWS cloud infrastructure
• Lead architecture and data modeling decisions across PostgreSQL, MongoDB, and vector storage
• Design and build integrations with third-party automotive APIs and dealership management systems (CDK, Fortellis, OEM APIs)
• Operate AI-first: leverage agentic coding tools (Claude Code, Cursor, Copilot) as a core multiplier in your daily workflow
• Set engineering standards — code review, testing practices, CI/CD, observability — as the senior technical voice on the team
• Collaborate directly with the technical co-founder on technical strategy, architecture reviews, and roadmap prioritization
• Mentor and eventually manage junior engineers as the team scales

Requirements:

• 4+ years of professional full-stack software engineering experience
• Strong proficiency with React or a modern frontend framework
• Deep experience with at least one compiled server-side language — C#/.NET preferred
• Production-grade experience with both relational (PostgreSQL, SQL Server) and document (MongoDB) databases
• Demonstrated use of AI-assisted and agentic coding tools as a core part of your workflow — not just familiarity
• Experience designing and owning systems end-to-end: schema design, API design, deployment, and observability
• Strong fundamentals: distributed systems, concurrency, performance optimization, and software design patterns
• Hands-on AWS experience: ECS/Fargate, Lambda, RDS, CloudWatch, CloudFormation
• Python experience for scripting, data pipelines, or ML/AI workflows
• CI/CD, Docker, and infrastructure-as-code experience
• Exposure to the automotive industry, DMS systems, or B2B SaaS in a vertical market
• Experience at an early-stage startup or founding engineering role
