Job Description

Tremend is looking for a seasoned Senior Data Engineer to join our growing Data Engineering practice at Tremend. In this role, you will design and deliver enterprise-grade cloud data solutions across modern cloud platforms, while providing technical leadership to a team of engineers working on complex migration and greenfield initiatives.

You will be a key technical voice in client engagements, shaping data platform strategies, driving engineering best practices, and bridging the gap between data infrastructure and AI/ML capabilities. If you thrive at the intersection of robust data engineering, cloud architecture, and applied intelligence, this is your role.

Responsibilities:

Lead the design and delivery of enterprise cloud data platforms, with hands-on experience on at least one major cloud provider (Azure, GCP, or AWS)
Architect and optimize large-scale data pipelines and lakehouse solutions using Databricks, Fabric, Apache Spark
Provide technical leadership and mentoring to a team of mid-level and junior data engineers — conducting code reviews, guiding architecture decisions, and ensuring engineering quality
Drive end-to-end data engineering initiatives: from requirements and design through to deployment, monitoring, and handover
Define and enforce data engineering standards including naming conventions, CI/CD practices, data quality frameworks, and documentation
Collaborate closely with data architects, ML engineers, and business stakeholders to translate complex requirements into scalable, maintainable solutions
Design and implement medallion architecture (Bronze / Silver / Gold) and Data Vault 2.0 patterns on cloud platforms
Support AI/ML integration patterns — building feature pipelines, inference data flows, and MLOps-adjacent infrastructure
Contribute to pre-sales and client scoping conversations, producing technical proposals and effort estimates for data platform engagements

Qualifications:

7+ years of hands-on data engineering experience, including at least 2 years in a tech lead or senior individual contributor role
Databricks knowledge about Delta Lake, Unity Catalog, Spark optimization, and cluster management
Strong cloud experience, ideally on GCP; extensive experience with Azure or AWS is also highly valued due to platform similarities
Advanced SQL and PySpark skills; ability to design performant transformations at scale
Experience implementing medallion architecture and/or Data Vault 2.0 methodologies in a cloud context
Solid understanding of data pipeline patterns: batch, micro-batch, and streaming (Kafka, Spark Structured Streaming,Pub-sub or equivalent)
Experience with CDC (Change Data Capture) patterns and tools
Experience using Terraform and deploying solutions to the cloud using Infrastructure as Code (IaC) practices
Proven hands-on experience with Snowflake and big data platforms in general
Strong communication skills — comfortable presenting architecture decisions to both technical teams and business stakeholders
Proven track record of mentoring engineers and contributing to team capability growth

Nice to Have:

Hands-on experience integrating data pipelines with AI/ML workloads — feature engineering, model serving data flows, or MLOps pipelines (MLflow, Vertex AI, Azure ML, or equivalent)
Exposure to LLM-based applications and the data infrastructure they require (vector stores, RAG pipelines, embedding pipelines)
Experience with legacy-to-cloud migration projects (IBM DataStage, Informatica, SSIS, Talend → cloud-native platforms)
Relevant cloud or Databricks certifications (Databricks Certified Data Engineer Professional, AWS/GCP/Azure Data certifications)
Knowledge of EU data regulations relevant to data platform design (GDPR, EU AI Act)
Experience working in financial services, retail, or other regulated industries
