Job description

Location: Mumbai, India (Andheri East)

Description: We’re hiring Senior Software Engineers to lead the design and delivery of robust, scalable, and production-grade data systems across a high-growth, multi-venture environment. This is a high-impact leadership role for someone who thrives in hands‑on build mode, and who can scale technical delivery without losing speed, quality, or ownership.

About Blenheim Chalcot

Blenheim Chalcot India is part of Blenheim Chalcot a global venture builder headquartered in London. With over 26 years of innovation, we've been at the forefront of creating some of the most groundbreaking GenAI-enabled companies. Our ventures lead the charge in digital disruption across a spectrum of industries, from FinTech to EdTech, GovTech to Media, and beyond. Our global presence spans the US, Europe, and Southeast Asia, with a portfolio that employs over 3,000 individuals, manages assets exceeding £1.8 billion, and boasts total portfolio sales of over £500 million.

The role

We’re hiring Senior Software Engineers to build scalable products, tools, and systems across our portfolio companies. This is a high-impact role for someone who thrives in hands‑on engineering, writes maintainable code, and is deeply motivated by solving real-world problems with technology. You’ll work closely with product and engineering colleagues in both Mumbai and London, driving delivery within a specific business. If you're passionate about engineering craft, product-led development, and delivering systems that scale, we’d love to hear from you.

Behaviours that we look for

• Solve problems rigorously, not reactively – breaking them down into tractable elements and considering multiple paths to resolution.
• Write clean, defensive code with clear structure and minimal complexity.
• Think about testing and observability early, automating meaningful tests and implementing relevant metrics/logging.
• Design systems for operations, not just development – considering CI/CD, resilience, cost, and scalability from day one.
• Use data to guide decisions, validating design impact, performance, and real user outcomes.

Key responsibilities

• Build and maintain scalable services, data pipelines, and backend systems.
• Write readable, efficient code and collaborate closely in code reviews.
• Automate robust test coverage (unit, integration, and/or contract tests).
• Implement data models used by analysts and ML teams; ensure schema evolution and data integrity are maintained.
• Participate in system design sessions and contribute to architectural discussions.
• Debug production issues across multiple services and layers of the stack.
• Contribute to CI/CD pipelines and infrastructure-aware development practices.

Opportunity

This is an excellent opportunity for experienced engineers looking to step up their scope and impact. You’ll join a collaborative team with exposure to modern engineering practices, GenAI-enabled systems, and business‑critical data products. You'll be part of a global network, shaping real customer outcomes.

About You

We are seeking to onboard candidates with a proven track record in engineering, demonstrating strong technical leadership skills and a passion for building high‑quality, scalable products. Excellent teamwork, adaptability, and a strategic mindset are essential to being successful in this role.

The Ideal Candidate

• Strong proficiency in at least one modern programming language (e.g., Python, Java).
• Experience with both SQL and NoSQL databases; schema design and query optimisation.
• Comfort with cloud platforms such as AWS or Azure (e.g., S3, Redshift, Glue, Synapse).
• Familiarity with CI/CD practices, automated testing, and observability.
• Knowledge of data structures, algorithms, and their real-world trade-offs.
• A proactive mindset: ready to take ownership, iterate fast, and learn continuously.
• Great communication and teamwork skills – particularly in cross-functional settings.

Process

We have a rigorous, but streamlined recruitment process, which respects the time of candidates and portfolio companies alike. This process starts with a 30-minute call with our Talent Acquisition team and a member of the Engineering Centre of Excellence, followed by further interviews with the Engineering Centre of Excellence team.

Please note that our roles are primarily office-based, with a modern and well-connected office location in Andheri East.
