Software Developer Contract information

What are the typical work arrangements and expectations for contract Software Developers?

Contract Software Developers are usually hired for specific projects or defined timeframes, which can range from several weeks to multiple months, often working remotely or on-site depending on client needs. They are expected to quickly understand project requirements, deliver code efficiently, and collaborate with both in-house teams and other contractors, maintaining flexibility to adapt to different workflows and tools. Because contract roles may not include the same onboarding experience as permanent positions, self-motivation and strong independent work habits are important. This work arrangement provides valuable exposure to various industries and technologies, often expanding a developer’s professional network and enhancing career versatility.

What are the key skills and qualifications needed to thrive in the Software Developer Contract position, and why are they important?

A successful Software Developer Contract requires strong programming abilities, solid knowledge of software development methodologies, and relevant project or domain expertise, often supported by a degree in computer science or a related field. Familiarity with languages like Java, Python, or JavaScript, as well as tools such as Git, Agile frameworks, and certification in areas like AWS or Scrum, is highly valued. Excellent problem-solving skills, adaptability, effective communication, and an ability to quickly integrate into new teams are crucial soft skills. These competencies enable contract developers to deliver high-quality solutions while efficiently navigating diverse projects and rapidly changing work environments.

What is a Software Developer Contract job?

A Software Developer Contract job is a temporary or project-based position where a developer is hired for a specific duration, typically through a contract agreement. Contractors may work independently, for an agency, or directly with a company to develop, test, and maintain software applications. These roles often offer flexibility but may not include benefits like health insurance or paid time off. Contract developers are usually paid hourly or per project and may work remotely or on-site depending on the employer's needs.

Job description

Description

Your role at GEI. 
 
The Data Engineer is responsible for designing, building, and maintaining the data pipelines and integrations that power GEI’s AI solutions and digital initiatives. This role focuses on ensuring enterprise data is accessible, reliable, and governed so that AI capabilities can be deployed and scaled with confidence.
 
The Data Engineer plays a hands-on role by preparing and integrating the data foundations that AI solutions depend on. This includes building ingestion pipelines, managing data stores, implementing quality and governance controls, and supporting retrieval patterns such as RAG. This role works closely with AI Engineers, solution architects, and platform teams to ensure data infrastructure is production-ready, secure, and aligned with GEI standards.
 
Essential Responsibilities & Duties 
  • Design, build, and maintain data pipelines that ingest, transform, and deliver enterprise data to AI solutions and business applications.
  • Develop and manage integrations across enterprise data sources using APIs, Graph connectors, event-driven architectures, and batch/streaming patterns.
  • Build and maintain data stores and indexing infrastructure that support retrieval-augmented generation (RAG) and other AI consumption patterns.
  • Implement data quality, validation, and lineage controls to ensure accuracy and trustworthiness of data feeding AI workflows.
  • Support and optimize data models underpinning Power BI dashboards and AI-enabled analytics.
  • Collaborate with AI Engineers to define data contracts and ensure pipeline outputs meet solution requirements for schema, latency, and freshness.
  • Instrument data pipelines for monitoring, alerting, cost control, and performance optimization.
  • Implement data governance and security controls including access management, encryption, and compliance with organizational data policies.
  • Identify data-related risks and support mitigation strategies in collaboration with architecture and platform teams. 
Minimum Qualifications 
  • 4+ years of data engineering experience, with demonstrated ability to build and operate production data pipelines.
  • Proficiency in Python and SQL; experience with PySpark or Spark is strongly preferred.
  • Experience with Azure data services, including Azure Data Factory, Azure Synapse Analytics, Azure Data Lake Storage, and Azure SQL.
  • Familiarity with Azure AI Search, Cosmos DB, or similar services used to support AI retrieval and storage patterns.
  • Experience building and managing ETL/ELT pipelines with structured, semi-structured, and unstructured data sources.
  • Knowledge of data modeling, schema design, and indexing strategies for both analytical and AI workloads.
  • Familiarity with infrastructure-as-code and CI/CD practices for data pipeline deployment (e.g., Terraform, Azure DevOps).
  • Knowledge of data governance principles, including data cataloging, lineage, access control, and privacy requirements.
  • Knowledge of security best practices for data solutions, including encryption at rest and in transit, role-based access control, and private networking.
  • Experience with Databricks, including Delta Lake and Unity Catalog, is a plus.
  • Prior experience in professional services, engineering, or construction environments is a plus.
  • Azure or Databricks certifications (e.g., Azure Data Engineer Associate, Azure Solutions Architect Expert, Databricks Data Engineer Professional) are a plus.
