Definian helps organizations define what’s next by unlocking the full value of their data. With expertise spanning data strategy, modernization, advanced analytics, and AI & automation, Definian equips leaders to navigate their digital evolution with clarity and precision.

The Opportunity:

Definian is hiring experienced Senior Software Engineers (Python) to join our growing team in Hyderabad, India.

This is a ground-floor opportunity to build new tools from scratch. You'll be working on the Definian Data Platform (DDP), our suite of internal tools that accelerate consulting delivery, as well as utilities and AI integrations that power our operations. Unlike maintaining legacy systems, this is greenfield development – you'll be creating new capabilities, not inheriting technical debt.

The DDP includes tools for code generation, data mapping, data lineage visualization, and an AI-powered coding assistant. You'll work with modern Python, cloud services, and AI/LLM APIs to build tools that make our consultants more effective and our delivery faster.

You'll be one of the first engineers on our India team, which means your contributions will be visible and your ideas will shape what we build. This isn't a role where you'll be executing someone else's detailed specifications – you'll collaborate with our India-based Software Architect and US technical leadership to define solutions and build them.

We are an AI-forward organization that embraces tools like Claude and Claude Code to accelerate development. You'll leverage these tools daily, and you'll be building systems that integrate with AI/LLM APIs – so your work will be at the intersection of development and AI.

This role demands strong Python skills, experience with APIs and cloud services, and genuine curiosity about AI/LLM technologies. For engineers who want to build new things, work with cutting-edge technology, and see their work have immediate impact, this is the kind of opportunity that accelerates careers.

What You'll Be Doing

Design and build new tools for the Definian Data Platform using Python
Develop REST APIs and web services using FastAPI, Flask, or Django
Integrate with AI/LLM APIs to build intelligent features
Leverage Claude and Claude Code to accelerate development workflows and solve complex problems efficiently
Build data processing pipelines and automation tools
Write clean, testable, well-documented code that others can maintain
Participate in code reviews – both giving and receiving constructive feedback
Collaborate with the Software Architect to define and implement solutions
Work with databases (PostgreSQL, SQL) to store and retrieve data efficiently
Contribute to improving development processes, testing practices, and documentation
Communicate effectively with US-based team members across time zones
Participate in sprint planning, estimation, and daily standups

Note: The responsibilities for this position could expand to include other duties based on the needs of the company and the skills of the candidate.

What You'll Bring to the Team

Required

4-6 years of professional software development experience
Strong proficiency in Python (3.8+)
Experience with web frameworks (FastAPI, Flask, or Django)
Experience building and consuming REST APIs
Experience with relational databases and SQL
Experience with version control (Git)
Strong communication skills – ability to work effectively with team members across time zones
Ability to work in a hybrid environment (4 days in Hyderabad office)
Graduate in Engineering or Bachelor of Science

Preferred Qualifications

Experience integrating with AI/LLM APIs (OpenAI, Anthropic, AWS Bedrock, or similar)
Experience with AI-assisted development tools, particularly Claude or similar LLM-based tools
Understanding of prompt engineering and context engineering principles for effective AI collaboration
Experience with AWS services (Lambda, S3, RDS)
Experience with data processing libraries (pandas, numpy)
Experience with CI/CD pipelines and DevOps practices
Experience with PostgreSQL
Experience with Docker and containerization
Exposure to front-end development (React, Vue, or similar)
Experience with unit testing (pytest)
Excellent communication and interpersonal skills
Exceptional attention to detail

Founded in 1985 as Premier International and rebranded in 2025, Definian combines four decades of trusted results with the energy of an AI-enabled future. We are proud to be recognized as one of Crain’s Best Places to Work in Chicago® and to be consistently named to the Inc. 5000 list for growth.

This is a complete architectural transformation – converting decades of COBOL and C++ legacy code into modern C# using object-oriented design principles and contemporary best practices.

What You'll Be Doing

Lead the architectural transformation of Applaud from COBOL/C++ to modern C# – reverse-engineering procedural logic and rebuilding it with object-oriented design
Write production-quality code in C#/.NET and Python – this is a hands-on role, not just oversight
Develop and maintain WPF desktop application components
Leverage Claude and Claude Code to accelerate development workflows and pioneer AI-assisted modernization approaches
Establish best practices for AI-assisted development across the India team
Contribute to the Definian Data Platform (DDP) architecture and development as a secondary focus
Mentor and guide India-based developers (C# and Python teams), conducting code reviews and establishing quality standards
Collaborate with the US Senior Architect to ensure architectural alignment across teams
Translate high-level architectural decisions into implementable designs and patterns
Identify and address technical debt while balancing delivery timelines
Document architectural decisions, design patterns, and technical standards
Serve as a trusted technical partner to leadership on this business-critical initiative
Participate in sprint planning, estimation, and delivery commitments

Note: The responsibilities for this position could expand to include other duties based on the needs of the company and the skills of the candidate.
