Job Description :
Full Stack AI Engineer
Role/Responsibilities :
- Author precise feature specs covering requirements, edge cases, constraints, and acceptance criteria before any code is written or AI agent is invoked.
- Own features end-to-end translating user outcomes into acceptance criteria, driving development through AI-assisted workflows, and validating output against the spec before delivery.
- Design and run generator-critic pipelines using AI to generate output and a structured critique pass against the same spec to validate it, iterating until acceptance criteria are met.
- Build and maintain software components APIs, data layers, services, and integrations as the engineering foundation that AI-native workflows operate on top of.
- Evaluate and adopt AI tools with structured reasoning assess new tooling against defined criteria, bring recommendations with evidence, and stay current with the evolving AI development landscape.
- Work autonomously across development, quality, and requirements minimising handoffs through disciplined spec authorship, self-managed validation, and proactive flagging of gaps before building.
Required Skills and Experience :
- Bachelor's degree in software engineering, Computer Science, or a related technical field.
- 5+ years of overall software development experience, with at least 3 years actively using AI tools as a core part of the development workflow.
- Proficiency in .NET, MS SQL Server (or equivalent RDBMS), MongoDB (or equivalent NoSQL), and API development.
- Ability to write structured, machine-precise specs that serve as ground truth for both code generation and output validation.
- Practical understanding of prompt construction, context engineering, and diagnosing AI output failures.
- Working awareness of the AI tool ecosystem intelligent system tooling (LLM APIs, RAG, vector databases, agent frameworks) and SDLC acceleration tooling (agentic coding, AI code review, AI test generation).
- Strong written communication skills and experience working in Agile or Kanban environments with end-to-end ownership of deliverables.
Nice to Have Qualities & Skills :
- Hands-on experience building RAG pipelines, working with vector databases, or integrating LLM APIs into production systems.
- Experience with multi-agent orchestration frameworks such as LangChain, LangGraph, CrewAI, or AutoGen.
- Familiarity with AI observability tooling such as LangSmith, LangFuse, or Braintrust.
- Exposure to spec-driven development practices such as BMAD or GitHub Spec Kit.
- Exposure to real estate technology, mortgage, or related financial services domain.
- Awareness of Model Context Protocol (MCP) and its role in connecting AI agents to external tools and data sources.
