About The Product

SecuArchAssist is an AI-powered STRIDE threat modelling platform. You give it a code repository and it rebuilds the C4 architecture, maps trust-boundary data flows, and runs parallel LLM agents to find, cross-validate, score (DREAD) and report security threats.

Roles & Responsibilities:

Expected to be an SME, collaborate and manage the team to perform.
Responsible for team decisions.
Engage with multiple teams and contribute on key decisions.
Provide solutions to problems for their immediate team and across multiple teams.
Lead efforts to identify and implement process improvements that enhance team productivity and software quality.
Mentor junior team members to support their professional growth and integration within the team.
Build and maintain the FastAPI backend that runs the threat-modelling pipeline for each project.
Extend the core stride-ai engine: repo ingestion, C4 reconstruction, DFD extraction, STRIDE agents, dedup and scoring.
Design async, concurrent LLM orchestration with asyncio, including retries, rate limiting and structured JSON output.
Model domain data with pydantic v2 and SQLModel/SQLite, and evolve the schema without breaking existing projects.
Write prompts and agents that return verifiable, evidence-backed findings, not hallucinated ones.
Keep test coverage high with pytest / pytest-asyncio.

Professional & Technical Skills:

Must To Have Skills: Proficiency in Python (Programming Language).
Strong knowledge of software development life cycle and agile methodologies.
Experience with modern software frameworks and tools to build scalable applications.
Ability to write clean, maintainable, and efficient code.
Familiarity with debugging, testing, and performance optimization techniques.
Good understanding of system architecture and integration concepts.
3+ years of backend work in Python 3.11+.
Strong with FastAPI, pydantic v2 and async Python.
Hands-on with LLM APIs (Anthropic and/or OpenAI), especially structured output and prompt design.
Working knowledge of applicaton security: STRIDE, auth/authz, and common vulnerability classes.
Good testing habits and clean, modular code.
