Senior Data Engineer
Summary
Senior Data Engineer at TEKsystems in Bangalore building and running a containerised data quality platform on Azure. Day to day: designing CI/CD pipelines in Azure DevOps, deploying services with Docker/Kubernetes (AKS), developing PySpark/SQL Server data pipelines, integrating Databricks workloads, and exposing RESTful APIs.
Key Responsibilities:
- Design, build, and maintain CI/CD pipelines using Azure DevOps for automated testing, container image builds, and deployment
- Containerise the data quality platform using Docker and manage deployment of container images across Business environments using Kubernetes
- Spin up and configure new container instances when onboarding new Business areas onto the platform
- Develop and maintain automated testing frameworks covering unit, integration, and end-to-end testing
- Design, build, and expose RESTful APIs to integrate the platform with upstream and downstream systems
- Collaborate with the Data Architecture team to ensure platform components are modular, platform-agnostic, and deployable across cloud and on-premise environments
- Work with Azure services including Azure Container Registry, Azure Kubernetes Service, Azure Key Vault, Azure Blob Storage, and Azure DevOps
- Develop and optimise data pipelines using PySpark and SQL Server
- Support the integration of Databricks workloads into the platform architecture
- Ensure platform security standards are met including secret management, image vulnerability scanning, and access controls
- Contribute to technical documentation, runbooks, and onboarding guides for Business teams
Required Skills & Experience:
- 8–12 years of experience in data engineering or platform engineering roles
- Strong hands-on experience with Azure services — AKS, ACR, Key Vault, Blob Storage, Azure DevOps
- Proven experience containerising applications using Docker and orchestrating with Kubernetes
- Solid experience building and maintaining CI/CD pipelines in Azure DevOps
- Experience designing and building RESTful APIs
- Proficiency in PySpark and SQL Server

- Strong understanding of software testing practices — unit testing, integration testing, end-to-end testing
- Experience with branching strategies, versioning, and release management
- Strong problem-solving skills and ability to work independently in a fast-paced environment
Preferred Skills:
- Understanding of Data Quality concepts — profiling, validation rules, DQ scoring, observability
- Experience with data quality tooling such as Informatica, Great Expectations, or similar
- Familiarity with Flask or similar Python web frameworks
- Experience with modular, microservice-style architecture design
What We're Looking For:
Beyond technical skills, we are looking for someone who takes ownership, thinks like a platform engineer, and understands that the best infrastructure is the kind that Business teams never have to think about. The ideal candidate is equally comfortable writing a Dockerfile, debugging a failing pipeline, and discussing deployment governance with a non-technical stakeholder.
