About this role

Job Description

We are seeking a Software Engineer with strong C++ and Python expertise to develop and support business-critical consumer data-processing systems. The role involves high-performance batch processing, data aggregation, calibration-support workflows, and reliable delivery of processed data to downstream platforms.

You will own features from technical design through production rollout, working across C++, Python, Oracle, and Linux-based orchestration.

Roles and Responsibilities

Design & Development

- Design, develop, and maintain high-performance C++ applications and reusable Python components for enterprise data-processing pipelines.
- Implement workflows for data extraction, transformation, aggregation, validation, and delivery.
- Apply modern C++ practices, including RAII, smart pointers, STL containers, and clear resource ownership, to build maintainable and reliable software.
- Develop and maintain Oracle-integrated processing components using SQL and existing Pro*C interfaces.
- Build and enhance Bash/KornShell scripts for application execution, workflow orchestration, and operational automation.
- Own technical designs, implementation, testing, documentation, and production rollout; contribute to architecture and design reviews.

Performance & Data Processing

- Optimize algorithms, data structures, memory usage, database access, and file I/O for large-volume processing.
- Develop and troubleshoot parallel processing workflows, addressing synchronization, resource contention, and safe concurrency.
- Work with partitioned datasets and structured data formats, including CSV and Parquet, across Oracle and cloud-connected processing environments.
- Maintain dependable interfaces between processing executables, Python modules, database packages, schedulers, and downstream systems.
- Improve pipeline scalability and recoverability through dependency management, controlled retries, locking, and safe rerun mechanisms.

Quality & Reliability

- Develop automated unit, integration, and regression tests for processing logic, database interactions, and failure scenarios.
- Diagnose crashes, memory issues, processing bottlenecks, and data discrepancies using logs, core dumps, debuggers, and profiling tools.
- Instrument applications with actionable logging, processing metrics, and resource-utilization monitoring.
- Participate in production support, incident investigation, root-cause analysis, and preventive improvements.
- Contribute to GNU Make-based builds, Docker packaging, GitHub Actions CI/CD, and code-quality checks.
- Follow secure coding practices, protect credentials, and manage third-party dependencies responsibly.

Collaboration & Leadership

- Conduct code and design reviews; mentor engineers in C++, Python, debugging, and performance engineering.
- Collaborate with Operations, Statistical Operations, Data Science, QA, database, and platform teams to translate business requirements into reliable solutions.
- Document processing logic, interfaces, dependencies, and operational recovery procedures.
- Evaluate development tools, including AI-assisted coding tools, while retaining responsibility for correctness, security, and maintainability.

Qualifications

Required Qualifications

- 3+ years of professional software-engineering experience, with strong hands-on C++ development and practical Python expertise.
- Strong knowledge of modern C++, preferably C++17, including object-oriented design, templates, STL, memory management, and resource lifecycles.
- Sound understanding of data structures, algorithms, concurrency, and performance trade-offs.
- Experience developing and supporting high-volume batch-processing or computationally intensive applications.
- Strong Linux/Unix skills, including process management, shell scripting, environment configuration, and production troubleshooting.
- Strong SQL and relational database skills, preferably Oracle, including complex queries, transactions, locking, and performance tuning.
- Experience with C++ debugging and profiling tools such as GDB, core-dump analysis, and memory diagnostics.
- Familiarity with GNU Make, GCC/G++, Git, automated testing, and CI/CD workflows.
- Strong problem-solving, technical ownership, and written and verbal communication skills.

Preferred Qualifications

- Experience with Oracle Pro C, OCI/OCCI, PL/SQL packages, SQL Loader, or embedded SQL.
- Experience with Python multiprocessing, database integration, and reusable data-processing utilities.
- Familiarity with Azure, Docker, Kubernetes, Azure Data Factory, Hive, or Parquet-based storage.
- Exposure to numerical computing, optimization algorithms, sparse matrices, or statistical data processing.
- Experience with GitHub Actions, Artifactory, SonarQube, and GitHub Copilot or comparable AI coding tools.
- Knowledge of consumer panel data, retail measurement, market research, or analytics-delivery platforms.
