Senior Tech Lead (Python)

Tech Lead

What You’ll Do:

• Own architecture and delivery of backend services and internal tooling (Python, FastAPI), from design to production reliability.
• Administer and harden

  Debian-based

  Linux systems; configure and optimize

  Nginx

  for API gateways, routing, and performance.
• Build robust data processing pipelines leveraging

  pandas, NumPy, SciPy,

  and related libraries.
• Design, deploy, and evaluate

  LLM

  and

  RAG

  features for search, summarization, and workflow acceleration—grounded in real customer constraints.
• Lead and grow a small engineering team: set standards, run reviews, mentor, and coordinate delivery.
• Champion security and on-prem architecture patterns that keep client data on their servers (no external operability).
• Ship under pressure: break down ambiguous goals, communicate trade-offs, and deliver incremental value fast.

What You'll Bring:

• Linux (Debian-based)

  administration and troubleshooting expertise.

• Python

  at an advanced level (typing, async, packaging, testing, performance).

• REST APIs

  with

  FastAPI

  (OpenAPI, validation, auth, async I/O, observability).

• Nginx

  configuration (reverse proxying, TLS, caching, rate limiting).
• Strong hands-on with pandas,

  NumPy, SciPy,

  and the broader scientific Python stack.
• Demonstrated,

  production

  experience with

  LLMs

  and

  RAG

  systems (evaluation, grounding, retrieval pipelines, vector stores or alternatives).
• Experience

  leading a small dev team

  (planning, reviews, mentorship, hiring signals).
• Proven

  team player

  who communicates clearly and thrives under pressure.

Nice to haves:

• Secure,

  on-prem

  deployments and data-at-rest/in-transit protections aligned with enterprise constraints.
• High speed NO-SQL databases (e.g., LMDB), high-throughput data processing, and performance profiling.
• Containers/CI-CD (Docker, GitHub Actions), infra-as-code (Terraform).
• Experience with vector DBs or retrieval alternatives.

Our Benefits:

• Competitive Compensation: Attractive salary package with equity.
• High ownership and direct impact on projects that influence investment decision-making processes at top global investment funds.
• Professional Growth: Access to the latest tools and tech in data science and finance, with abundant learning opportunities.
• Flexible hours and remote work options in a supportive and inclusive company culture.
