Job Description:

Education: Engineer (or equivalent) degree in computer engineering or computer science. Experience: 6-8 Years of Experience

• Develop and maintain data pipelines for efficient data extraction, transformation, and loading (ETL/ELT) processes, utilizing PySpark for distributed big data processing and Polars/Rust for maximal performance and memory safety in single-node bottlenecks.

• Design, implement, and own internal process improvements: automating manual processes, optimizing data delivery latency using high-speed language components, and re-designing infrastructure for greater scalability and cost efficiency.

• Work on the data pipeline operations to operate, maintain, and evolve our decoding pipelines, proposing improvements to automatize and industrialize all processes and ways of working with a focus on data quality and platform stability.

• Support the ramp-up and installations of data pipeline for future airline/aircraft deployment.

• Integrate high-performance Rust-compiled routines (e.g., UDFs) into Python and PySpark workflows to resolve critical performance issues.

• Rust: Strong proficiency in Rust for developing memory-safe, highly concurrent, and low-latency data processing microservices or core pipeline components. Familiarity with the Cargo package manager.

• Polars (Expert Level): Mastery of Polars for high-speed, multi-threaded data manipulation on single machines. Deep understanding of the Lazy API, Apache Arrow columnar format, and query optimization techniques (e.g., predicate and projection pushdown).

• Python: Deep expertise in writing production-grade, modular, and reusable code (including Python packaging/wheels). Proven ability to orchestrate complex workflows and tooling.

• PySpark (Expert Level): Mastery of PySpark internals, including:

  • Advanced Performance Tuning: Expertise in diagnosing and resolving bottlenecks using the Spark UI. Deep understanding of Adaptive Query Execution (AQE), data skew mitigation, and optimizing shuffles.

  • Transactional Data: Experience with Delta Lake, Apache Hudi, or Apache Iceberg for building reliable, ACID-compliant Data Lakehouse architectures (handling UPSERTs, Time Travel).

• SQL (Expert Level): Expert proficiency in analytical SQL (window functions, CTEs) and database optimization (indexing, partitioning, query plan analysis).

• Workflow Orchestration (e.g., Apache Airflow, Dagster): Proven experience in designing, deploying, and maintaining complex, dependency-driven DAGs in production environments, including failure recovery and alerting.

• Infrastructure-as-Code (IaC): Hands-on experience with Terraform or CloudFormation to provision, manage, and secure cloud data resources and compute clusters.

• Cloud Platforms (AWS/Azure/GCP): Hands-on experience with core cloud data services and cost-management practices (e.g., EMR/Dataproc, S3/ADLS/GCS, and serverless compute).

• Data Quality & Lineage: Experience implementing robust data quality checks (e.g., Great Expectations) and integrating with Data Catalog/Lineage tools.

• Security & Access Control: Practical experience implementing least-privilege access (IAM/RBAC), data encryption, and data masking/tokenization for sensitive data (PII/PHI).

• CI/CD & Testing: Strong knowledge in building automated test, lint, and deployment pipelines (Jenkins, GitLab CI) for data services. Ability to write comprehensive Unit Tests and Data Validation Tests.

• Domain Specific: Palantir (Skywise) experience good to have.

• Good communication skills, including the ability to articulate the technical trade-offs between distributed (PySpark) and high-speed single-node (Polars/Rust) solutions to technical and non-technical stakeholders.

• Sound knowledge in Agile/SAFe methodologies.

• Ownership Mentality: Ability to handle a subject from demand management, to development, and long-term production support.

• Ability to solve complex networking, data, and software issues.

• Good to have exposure in aviation industries.

This job requires an awareness of any potential compliance risks and a commitment to act with integrity, as the foundation for the Company’s success, reputation and sustainable growth.
