Sr. Back End Developer (AI-native)

VDart Inc

Job Title/Function: Sr. Back End Developer (AI-native)

Duration: 6 month contract-to-hire

Address : 26 S. Rio Grande St. #2072 Salt Lake City, UT 84101

Main responsibilities :

Day in the Life: Can plan for a feature, develop prototype fast with AI and then, after presenting to testers and getting feedback, realize it is missing context or needs new details and jump back into it with a very agile mindset.
Supporting any current/upcoming projects: Experienced enough with AI to ask questions like, "Will we charge client for token?" and is security-minded developer so they can respond to clients quickly
Training/ramp up: They will get soon after starting a $200 Claude Max subscription setup for them to use

Requirements :

MUST HAVE -
- Close to 1 year AI-native engineering - Someone who extends AI capabilities, not just consumes them. Plenty of developers "use AI tools," but very few have actually built MCP servers or designed agent tooling.
  - Experience w/ modern LLM's like Claude Code, GPT-4, etc.
    - Building and hosting MCP servers
    - Designing custom tools and skills for AI agents
    - Orchestrating multi-agent workflows
    - Designed agent tooling
- 5+ years Backend architecture with API design
  - Able to design and build microservices, RESTful APIs, and database schemas.
  - The specific stack (Python/FastAPI/PostgreSQL) is learnable; the architectural thinking is not.
- CI/CD pipeline building experience. They use GitHub Actions - there is no more DevOps team
- Self-directed problem solver - ability to pick up unfamiliar codebases, tools, and frameworks quickly without hand-holding. In an AI-first team, the bottleneck is never "do you know library X" - it's "can you figure out the right approach and execute."
Soft skills:
- OK with a speed first mentality ahead of quality if not fundamentally against best practices - sustainable but can be fixed if needed.
- Senior who can deploy something on their own and drive it forward without waiting for everyone else
- No ego, no stupid questions mentality
- Tight-knit collaboration mindset
- Holds themselves accountable for being available during business hours

NICE TO HAVE
- Modern JavaScript frameworks experience for Front End development
- Python
- GCP cloud experience

Claude Code experience with models like Opus and Sonnet
