As a Lead Data Engineer, you’ll work closely with our customers to provide scalable and maintainable data solutions for reporting, data science and automation use cases in a variety of industries. This role combines consulting, technical and leadership skills in customer-facing settings and is important for the further development of our established function.  

The ability to produce efficient architectures, data models and processing pipelines to automate the ingestion, integration and serving of data for analytics while ensuring the quality of the solution is an essential aspect of the role.  

Depending on the project allocation, our roadmap and your motivations, your daily responsibilities could be varied. Typically, our Lead Data Engineers:

  • Estimate the delivery and operating costs of the solutions.  
  • Lead the development of data platforms and data engineering pipelines by establishing patterns and supporting the delivery team to ensure quality of the solution.  
  • Contribute to multiple projects in their area of expertise.  
  • Support pre-sales and marketing activities as a subject matter expert.  
  • Contribute to internal initiatives to improve the established practices or introduce new ones. 
  • Contribute to the team growth by interviewing candidates and sharing knowledge with the wider data engineering community in Ascent. 


Skills and experience required 

We’re looking for people with good data engineering skills, and you’ll ideally bring with you: 

  • Extensive experience with architecture and design of complex applications across various data domains and platforms with optimisation of performance and cost in mind.  
  • Strong experience in data modelling including multiple techniques for performant analytics workloads.  
  • Good understanding of Agile and DevOps principles, and strong experience with toolsets such as Azure DevOps and GitHub. 
  • In-depth understanding of Azure PaaS data engineering stack, such as SQLDB, Synapse, Data Factory, Data Lake Storage, CosmosDB, Azure ML. Databricks and Snowflake with be considered highly advantageous.

We work in Agile methodologies as a preference, so being comfortable working in this way is important. You should be comfortable in a customer-facing situation where you’ll need to communicate clearly and effectively in English – often with people who might not be as technically experienced, so good written and verbal English skills are essential. You should be passionate about team collaboration and knowledge sharing, with the passion and drive to achieve goals and targets. We value empathy in our colleagues, and it’s important you bring a growth mindset and a willingness to learn and adapt. 


Working at Ascent 

We choose hybrid working, where you balance time at the office or with your customers with working at home. On some occasions, you will be expected to participate in client workshops onsite. You'll earn a competitive salary, with a good range of benefits. Our offices are places to connect and collaborate with colleagues, with socials and regular get-togethers. We take your development and growth seriously, with plenty of opportunities to acquire skills and get certified.
