Senior Data Platform Engineer information

What does a senior data platform engineer do?

A Senior Data Platform Engineer is responsible for designing, building, and maintaining large-scale data platforms that support an organization's data analytics and processing needs. They work with various technologies to ensure data is collected, stored, and accessible efficiently and securely. Their role often involves optimizing data pipelines, managing databases, ensuring data quality, and collaborating with data scientists and analysts to deliver reliable data solutions. In addition, they help set best practices and mentor junior engineers on the team.

How does a senior data platform engineer typically collaborate with data scientists and analysts within an organization?

A Senior Data Platform Engineer works closely with data scientists and analysts to understand their data needs and ensure the platform supports efficient data access, processing, and analysis. This often involves designing and implementing data pipelines, optimizing data storage solutions, and ensuring data quality and integrity. Regular communication is essential to align on data requirements, troubleshoot issues, and roll out new platform features that enhance analytical capabilities. Collaboration frequently occurs through agile ceremonies, project meetings, and shared documentation to ensure all stakeholders are aligned and productive.

What are the key skills and qualifications needed to thrive as a senior data platform engineer, and why are they important?

To thrive as a Senior Data Platform Engineer, you need deep expertise in data architecture, database management, ETL design, and programming languages like Python or Java, typically supported by a bachelor's degree in computer science or related field. Familiarity with cloud platforms (such as AWS, Azure, or GCP), big data tools (like Spark or Hadoop), and certifications in relevant technologies are commonly required. Strong problem-solving, collaboration, and communication skills set top performers apart in this role. These competencies are essential for building robust, scalable data systems that support business intelligence and data-driven decision-making.

What is the difference between Senior Data Platform Engineer vs Data Engineer?

AspectSenior Data Platform EngineerData Engineer
CredentialsBachelor's/Master's in CS, Data Science, or related; often certifications in cloud platformsBachelor's in CS, Software Engineering, or related; certifications in data tools are common
Work EnvironmentDesigning, building, and maintaining large-scale data platforms; working with cloud servicesDeveloping data pipelines, ETL processes, and data storage solutions
Industry UsageUsed across tech, finance, healthcare, and retail for managing data infrastructureCommonly employed in similar industries for data processing and integration

The Senior Data Platform Engineer focuses on designing and maintaining scalable data platforms, often with cloud expertise, while Data Engineers primarily develop data pipelines and ETL processes. Both roles require strong technical skills and are vital in data-driven organizations, but the Senior Data Platform Engineer typically has a broader scope and more strategic responsibilities.

Job description

Clio is the global leader in legal AI technology, empowering legal professionals and law firms of every size to work smarter, faster, and more securely.

We are transforming the legal experience for all by bettering the lives of legal professionals while increasing access to justice.

Summary:

We are currently seeking a Senior Data Platform Engineer to join our rapidly growing Security team and help grow our Logging Engineering team. This role is for someone passionate about building scalable logging architectures, designing robust data pipelines, and driving security-focused logging automation at scale. You will help lead, support, and implement the technical architecture for our logging infrastructure while making a tangible impact on our security observability.

This role is available to candidates across Canada. If you are local to one of our hubs (Burnaby, Calgary, or Toronto) you will be expected to be in office minimum two days per week for our Anchor Days.

What your team does

Are you someone who's always probing and asking why, someone who enjoys architecting elegant solutions to complex data pipeline challenges? If so, we have a spot for you on Clio's Logging Engineering team! We are looking for candidates to help design and evolve our logging platform architecture, supporting the team with technical leadership for security logging overall. If you have a strong data engineering background with a passion for security and experience building enterprise-scale logging platforms, then we want to talk to you.

A day in the life might look like:
  • Contributing to the design and architecture of scalable logging infrastructure including data lakes, security lakes, and multi-tier storage strategies

  • Building and optimizing high-throughput log ingestion pipelines using streaming technologies and cloud-native services

  • Architecting ELK stack deployments, OpenSearch clusters, and hybrid cloud logging solutions

  • Designing data retention, lifecycle management, and cost optimization strategies for petabyte-scale log storage

  • Partnering with the security team lead to develop the logging platform roadmap and technical vision

  • Building Infrastructure as Code for logging infrastructure provisioning, scaling, and disaster recovery

  • Optimizing query performance across multiple data stores and implement efficient data partitioning strategies

  • Designing API and integration layers for log data access, enabling self-service analytics and detection engineering

  • Contributing to capacity planning, performance tuning, and architectural decisions for the logging platform

  • Mentoring engineering team members on logging best practices, data architecture, and platform operations

What you may have:
  • Proven Senior-level expertise building enterprise-scale logging and data ingestion systems, typically gained over 5+ years of relevant experience

  • Data architecture experience designing data lakes, lake houses, and multi-tier storage architectures for log data

  • Mastery of big data technologies and processing systems including but not limited to Splunk, OpenSearch, ElasticSearch & the ELK Stack, Map Reduce, Hadoop, Cassandra, and other comparable data ingestion & query systems

  • Experience in Data Modelling using one or more methodologies like Kimbal, Inmon, or Data Vault for data-at-rest schema normalization

  • Streaming data expertise with Apache Kafka, Amazon Kinesis, AWS Glue, Azure Event Hubs, or similar real-time ingestion platforms

  • Cloud storage architecture experience with AWS S3, Azure Data Lake, GCS, and intelligent data tiering strategies

  • Performance optimization skills for high-volume data ingestion, indexing strategies, and query optimization

  • Infrastructure as Code proficiency with Terraform, CloudFormation, or similar for logging infrastructure automation

  • Data pipeline engineering experience with Apache Spark, Flink, or cloud-native data processing services

  • API and integration design for enabling secure access to log data across multiple consumer applications

  • Monitoring and observability expertise for logging platform health, performance metrics, and capacity planning

  • An AI first mentality, where your decision making, coding, and throughput are amplified through your AI usage

Serious bonus points if you have:
  • Programming proficiency in Python, Ruby, Go, or Scala for custom logging pipeline development and automation

  • Experience with SQL Data Warehouse Dimensional Modelling using Kimball, Inmon, Business Data Vault or other modelling techniques.

  • Kubernetes and Container encapsulation for logging architecture within cloud-native application systems.

  • Security-focused logging experience with SIEM integration, security data lakes, and compliance-driven data retention

  • Multi-cloud logging architecture designing consistent logging platforms across AWS, Azure, and GCP

  • Data governance expertise implementing data classification, privacy controls, and regulatory compliance for log data

  • Advanced analytics platforms experience with Splunk Enterprise, Sumo Logic, or other enterprise logging platforms

  • Cost optimization expertise for large-scale data storage, implementing intelligent archiving and data lifecycle policies

  • Technical leadership experience mentoring teams, setting architectural standards, and driving technical strategy

This role is a backfill for an existing position.
