Innovate. Create. Elevate.

At Ontrac Solutions, we partner with elite engineering organizations to build systems that operate at planetary scale.

Our client, a founding search company, is evolving the foundation of its core search platform — and we are looking for a Python Engineer who does not just use Python… but understands it at its core execution model.

This is not a feature role.
This is not application engineering.
This is infrastructure that shapes user experience at massive scale.

The Mandate

Design and optimize the Python systems that power:

  • Global indexing pipelines
  • Real-time search services
  • Ranking and relevance models
  • High-QPS distributed APIs
  • ML-integrated search architecture

You will operate where performance, scale, and precision intersect.

The Environment You'll Influence

You'll work alongside teams leveraging:

  • Apache Lucene
  • Elasticsearch
  • Apache Solr
  • Apache Kafka
  • Hadoop
  • TensorFlow
  • PyTorch

This is distributed systems engineering at scale.
Latency matters. Throughput matters. Architecture matters.

Experience

  • Has 8+ years of Python engineering in production
  • Understands CPython internals and performance trade-offs
  • Has optimized systems around GIL, async I/O, multiprocessing
  • Has built high-throughput services serving millions of users
  • Has architected distributed systems end-to-end
  • Can debug performance issues at memory and execution level
  • Has operated at Staff or Principal level with architectural ownership

You don't just ship code.
You design systems that scale.

What You'll Actually Do

  • Architect low-latency Python services supporting core search
  • Optimize indexing and ranking pipelines
  • Improve query response times at scale
  • Design concurrency strategies for performance-critical systems
  • Influence system-level architectural decisions
  • Mentor senior engineers and elevate technical standards
  • Bridge ML-driven ranking systems with production-grade infrastructure

The Impact

Your work will:

  • Directly influence millions of search queries
  • Reduce latency across global systems
  • Increase relevance accuracy
  • Improve infrastructure resiliency
  • Shape the evolution of search architecture

This is high-visibility, high-impact engineering.

What Makes This Opportunity Different

Through Ontrac Solutions, you're not just stepping into a contract role.
You're joining a performance-driven engineering ecosystem.

We operate with:

  • Enterprise precision
  • Architectural rigor
  • Clear executive alignment
  • Outcome-driven delivery

We partner with organizations where technical excellence is not optional — it's foundational.

Ideal Background

You may have:

  • Built large-scale search platforms
  • Worked on marketplace or ad-tech systems
  • Led distributed systems architecture
  • Contributed to open-source Python libraries
  • Operated in environments where uptime > 99.9% is mandatory

Experience in relevance engineering, information retrieval theory, or ML-driven search pipelines is highly valued.

Why This Role Is Elite

This is not CRUD engineering.
This is not startup experimentation.
This is not maintenance work.

This is:

  • Distributed systems at scale
  • Performance-critical Python engineering
  • Search infrastructure modernization
  • Architecture with real global impact

About Ontrac Solutions

Ontrac Solutions partners with enterprise platforms and high-growth organizations to deliver Cloud, AI, and Digital Product Engineering at scale.

We operate at the intersection of:

  • Control
  • Clarity
  • Velocity
  • Institutional Trust

If you are a Principal engineer who thrives in performance-critical environments and wants to build infrastructure that matters — we should talk.
