Job Description

We are looking for a Senior C++ Engineer to join our core backend engineering collective. This is a high-impact opportunity to shape future trends in data processing and high-performance computing. You will be at the forefront of evolving a platform that handles massive, multi-dimensional datasets, ensuring our technical architecture remains a benchmark for the industry. You won't just write code; you will influence the trajectory of our engineering culture and the scalability of our global infrastructure.

Job Responsibility

  • Architectural Stewardship: You will lead the design and implementation of High-Level (HLD) and Low-Level Designs (LLD), ensuring our systems are loosely coupled, highly scalable, and resilient
  • Product Lifecycle Ownership: Take full accountability for the software lifecycle—from initial inception and high-performance C++ development to automated deployment and maintenance via Infrastructure as Code (IaC)
  • System Evolution: Modernize legacy components into high-throughput distributed systems, applying both Object-Oriented and Functional programming paradigms to solve complex data bottlenecks
  • Cross-Functional Collaboration: Partner with Data Scientists and Cloud Architects to bridge the gap between complex algorithmic requirements and robust production-grade engineering
  • Global Mentorship: As a senior member of a distributed team (UK & India), you will drive engineering excellence through code reviews, design critiques, and fostering an Agile environment of continuous improvement

Requirements

  • 6-10 years of professional software development experience, with at least 6 years dedicated to C/C++ in performance-critical environments
  • Expert-level C/C++ and robust Shell Scripting for automation
  • Strong fluency in Relational Databases and SQL optimization
  • Deep understanding of Distributed Computing, High-Performance Systems, and OOP/Functional programming principles
  • A solid foundation in computer science fundamentals, including memory management, concurrency, and network protocols
  • The ability to navigate ambiguity and provide technical clarity to junior engineers and non-technical stakeholders
  • A rigorous approach to high-quality coding standards and a 'fail-fast' mentality in testing

Nice to have

  • Experience with GCP or Azure, and workflow orchestration via Airflow
  • Hands-on experience with Docker and Kubernetes (K8s)
  • Proficiency with Git and building automated CI/CD pipelines
