Senior Software Engineer

Definian helps organizations unleash the full potential of their data. Our expertise in data-led business transformation, data fundamentals and migration, risk management and data value realization helps companies maximize the value of their data, empowering them to achieve success across the entire data value chain. Having successfully completed thousands of projects since our founding in 1985, many of the world’s leading brands, technology companies, and system integrators rely on Definian to solve their most complex data challenges.

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.

• 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.

• 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

• 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
