Overview

We are hiring a Mid-to-Senior Full Stack Developer to build and extend an Agentic AI platform with strong focus on LLM workflows, orchestration, and backend systems. This role requires a highly independent engineer who can quickly understand existing codebases and deliver production-quality enhancements with minimal guidance.

Core Hiring Bar (Non-Negotiable)

  • Ability to independently read, understand, and modify moderately complex Python modules (~300+ lines)
  • Comfortable filling knowledge gaps through documentation and reasoning (not dependent on AI-assisted coding tools)
  • Demonstrated ability to interpret existing systems and implement changes with minimal onboarding

Key Responsibilities

  • Develop and enhance backend services and agentic workflows for the AI platform
  • stateful, multi-step LLM pipelines and orchestration logic
  • Design, optimize, and maintain retrieval and scoring systems
  • Debug production issues using logs, traces, and system behavior
  • Collaborate across teams to deliver scalable and reliable AI-driven solutions
  • Implement incremental changes with strong testing and validation practices

Technical Requirements

Python (Senior Level)

  • Writes clean, idiomatic Python using: 

    • Type hints, dataclasses, Pydantic
    • Generators and context managers
  • Strong understanding of: 

    • Async/await and concurrency models
  • Proficient in Python standard libraries (e.g., pathlib, json, re, collections)

  • Able to modify existing complex systems independently

Backend Development (FastAPI)

  • Experience building and extending FastAPI services

  • Strong understanding of: 

    • Request lifecycle
    • Dependency injection and middleware
    • Multi-worker deployments and shared state (e.g., Redis)
  • Able to diagnose issues using logs and traces (minimal debugger reliance)

LLM Engineering (Applied)

  • Experience building production-grade LLM workflows

  • Strong in:

  • Deterministic prompt design (structured outputs, low/no temperature)

  • Handling failure modes (timeouts, malformed outputs)

  • Understanding of RAG systems: 

    • Chunking, embeddings, similarity scoring

Workflow Orchestration (LangGraph or Equivalent)

  • Experience with stateful orchestration frameworks preferred

  • Must be able to quickly: 

    • Learn graph/state concepts
    • Implement multi-step workflows within 1–2 weeks

Retrieval & Scoring Systems

  • Experience with ranking/scoring methods (e.g., BM25, hybrid search)

  • Ability to tune: 

    • Thresholds, weighting, precision vs recall trade-offs
  • Capable of building realistic test datasets

Diagnostics & Log Processing

  • Familiar with log ingestion and analysis pipelines

  • Understands: 

    • Chunking strategies
    • Pattern extraction vs LLM reasoning
    • When to use deterministic vs AI-based parsing

Infrastructure & Runtime

  • Hands-on experience with: 

    • Docker / Docker Compose (volumes, dependencies, health checks)
    • Debugging container runtime issues
  • Working knowledge of:

  • Redis (basic operations, TTL, persistence)

  • Enterprise networking concepts (e.g., proxies)

Frontend (Working-Level)

  • Ability to work with HTML + Vanilla JavaScript

  • Comfortable with: 

    • DOM manipulation
    • Fetch APIs and event handling
  • Able to implement UI changes from requirements (no design dependency)

Work Style Expectations

  • Strong code-first discipline (understands design before coding)

  • Built-in focus on: 

    • Testing and validation
    • Log-driven debugging
  • Writes clean, incremental changes with clear commits

  • Performs self-review against acceptance criteria

  • Asks focused, implementation-driven questions

Experience & Seniority

  • Level: Mid to Senior Engineer

  • Experience: 

    • ~4–8 years in Python development
    • Proven track record delivering production systems
    • Experience with LLM-based or AI platforms preferred

Ideal Candidate Profile

  • Highly independent problem-solver

  • Strong systems thinker (not just feature coder)

  • Comfortable working in low-AI-assist environment

  • Bias toward execution, debugging, and delivery quality
