Collabera is seeking a Junior-Intermediate Python Engineer to join the IBOR team, supporting a mission-critical reconciliation and trade support system.

This role is driven by increased risk ownership within the team, as they take on an existing Python-based application responsible for front-office reconciliation and trade locate workflows. This system is critical to ensuring accurate asset positioning for trading activities.

The engineer will play a key role in stabilizing, enhancing, and gradually transforming this application into a more scalable, modular data platform over the next 12-18 months.

This is a hands-on engineering role with a strong mix of backend development and data engineering, requiring someone who can think beyond code and understand system behavior, data flows, and reliability in production environments.

Day-to-Day Responsibilities:

The Python Engineer will focus on developing and maintaining backend services that support a high-availability, SLA-driven system.

A large portion of the role involves working with an existing Python codebase—debugging, enhancing, and modularizing components as the team transitions the system into a broader ecosystem.

They will work heavily with data, including writing and optimizing SQL queries, performing data validation, and supporting reconciliation workflows tied to trading operations.

The engineer will also contribute to improving system reliability and data quality, troubleshooting production issues, and ensuring the platform meets strict SLA requirements.

Additional responsibilities include collaborating with team members to distribute system knowledge, contributing to design discussions, and supporting cloud-based infrastructure (primarily AWS).

Must-Haves:

* 2-5 years of professional experience in software engineering (not entry-level)

* Strong hands-on experience with core Python (beyond just frameworks)

* Solid SQL skills (joins, data validation, debugging queries)

* Experience with AWS or similar cloud platforms

* Understanding of backend service development and system fundamentals

* Exposure to data engineering concepts (data pipelines, transformations, data quality)

* Strong debugging and problem-solving skills

* Ability to work in a fast-paced, production-critical environment

Plusses:

* Experience with high-availability or low-latency systems

* Exposure to capital markets / public markets

* Experience working with systems that have strict SLAs

* Familiarity with distributed systems or large-scale data platforms

* Experience working on data-intensive applications
