Job description:

- Own and build data features end to end, working across data pipelines and services and taking them through to production.

- Understand the data, its sources, and its intended uses, and design and evolve data models that are clear, maintainable, and reusable.

- Help design and deliver the gradual migration from Matillion to a code-driven orchestration and transformation platform, preserving reliability throughout the transition.

- Build and improve our data pipelines and infrastructure, from ingestion and transformation to orchestration, reliability, and production operation.

- Work with business and product stakeholders, clients, and vendors to understand needs, investigate problems, and turn them into practical technical solutions.

- Contribute to the evolution of our data platform, including data quality, governance, observability, and AI-powered capabilities.

Requirements:

- Strong software engineering fundamentals, with experience building and operating production data pipelines and ingestion systems.

- Strong SQL and data modeling skills, with experience working with layered transformation patterns such as raw/staging, intermediate, and curated data models.

- Good understanding of software engineering practices such as automated testing, CI/CD, and production observability.

- Ability to independently own and deliver complex engineering work, from stakeholder collaboration and understanding the problem through implementation and production operation.

- Good verbal and written English communication skills.

- What brings extra points?

- Hands-on experience with Snowflake, dbt, Fivetran or other ingestion frameworks, Terraform, TypeScript, or Python.

- Experience building distributed systems, asynchronous workflows, or orchestration systems.

- Experience designing data quality, observability, or governance systems.

- Experience building or improving development harnesses for coding agents and agentic workflows.

- Experience developing AI agents or systems that provide AI applications with access to structured company data.

- What we value

- You don't need to know every tool in our stack. What matters more is that you're curious, proactive, and motivated to grow.

- We value engineers who like to understand how things really work, take ownership beyond the initial implementation, and enjoy working closely with people across business functions. You should enjoy turning ambiguous problems into practical solutions and continuously expanding what you can take on independently.

- Why Celtra?

- Impact: Create high-quality digital work for leading global brands across a wide range of campaigns and formats.

- Culture: We're inventive, collaborative, and proudly a little bit quirky - because doing great work should also be fun.

- Flexibility: Hybrid with strong hubs in Ljubljana, London and New York, and team get-togethers that keep us connected.

- Growth: You'll learn from experienced team members and grow into bigger roles as you go.

We offer:

- Flexible working hours and hybrid work based on a fixed number of in-office days.

- A dedicated educational budget to explore new skills and deepen your expertise.

- Equipment of your choice.

- Knowledge shares.

- Additional pension and health insurance.

- WFH budget. An additional budget of 500 EUR to set up your home space.

- Employee well-being. Dedicated budget for any kind of wellness activities such as fitness, yoga, etc.
