Engineering Team Lead

Lead a small engineering team building high-volume, data-intensive systems that transform complex enterprise data into accurate, machine-readable outputs. You'll work closely with the founder on architecture and own system reliability, scalability, and correctness.

This is not a pure people-management role. You'll remain deeply hands-on with architecture, production systems, and technical decisions. You'll also be expected to operate effectively in ambiguity and challenge existing architectural decisions when needed.

Responsibilities:

• Drive architecture across TypeScript/NestJS workflows and Python data/AI services.
• Build reliable long-running workflows with durable execution, retries, and idempotency.
• Design scalable data processing using Polars, DuckDB, Parquet, and streaming.
• Build evaluation and regression frameworks to measure AI/system accuracy.
• Own production systems running in customer cloud environments.
• Lead hiring, code reviews, technical decisions, and mentor engineers.
• Maintain clean boundaries between workflow orchestration, AI/agent execution, and bulk data processing.

Requirements:

• 5-7 years building backend, distributed, or data-intensive systems.
• Strong expertise in Python or TypeScript, with working proficiency in the other.
• Experience taking systems from design production and ongoing ownership.
• Strong understanding of distributed systems, retries, idempotency, failures, and long-running workflows.
• Hands-on experience with high-volume data processing.
• Engineering leadership experience mentoring, reviewing, and raising technical standards.
• Strong focus on correctness, observability, and production reliability.
• Tech Stack: Python, TypeScript, NestJS, Temporal, LangGraph, Polars, DuckDB, Parquet, Pydantic, PostgreSQL, Redis, Azure, Docker, Terraform/Bicep, React

Strong Plus:

• Temporal or similar workflow orchestration platforms.
• LLM/AI systems with measurable evaluation.
• Polars, DuckDB, Arrow, Parquet.
• Azure and enterprise cloud environments.
• LangGraph / agentic workflows.
• Docker, Terraform/Bicep, OpenTelemetry.
