Junior Infrastructure Engineer

Sifflet is used by technical and less technical users alike. The design and implementation of the Sifflet web UI are critical to ensure our product is usable by all targeted personas, including data engineers, data analyst, business users…

As a frontend engineer, you’ll join one of our feature teams to implement new features in the Sifflet web UI or browser extensions, and ensure the user experience meets our standards. In this role, you will:

• Collaborate with product managers, designers and backend engineers to brainstorm, design and implement innovative user-facing features.
• Enhance our frontend architecture, framework and design.
• Develop reliable quality standards for our frontend framework.
• Collaborate with the rest of the engineering team to shape the culture of the team, hire new people, and in general contribute to a smoothly running team.
• Work with anyone across the company to make Sifflet better everyday!

Some projects you could be working on

• Implement a new lineage visualisation between data assets which can scale to handling thousands of assets - this is both a technical and a UI design challenge.
• Extend our design system with new components supporting complex interactions and visualisations.
• Optimise the performance of some key screens of the application.

Our stack

• The web UI is a Vue.js application written in Typescript, tested with Cypress and Jest. The API client is autogenerated from OpenAPI definitions.
• The API is written in (modern) Java, to tap into the huge data ecosystem offered by this language; Spring Boot 3. Other teams at Sifflet also use Python. You may occasionally need to read or contribute small changes to these codebases.
• Infrastructure: Kubernetes, MySQL, Temporal for job orchestration.
• And a few supporting services: Gitlab CI, Prometheus/Loki/Grafana, Sentry…

Software engineering degree or equivalent relevant experience. This position is open to new graduates. Some general knowledge around these topics: web architecture, data engineering, cloud infrastructure… Of course, you don’t have to know everything upfront, you’ll pick up what you need on the job. We’re looking for engineers that are willing to learn many different areas quickly and don’t consider anything as “out of my scope”. This position requires working on Python, Java and Go codebases, and includes a significant share of software development and data engineering on top of the usual infrastructure work. You take ownership of your projects from design to production, and aren’t afraid of taking initiatives. We value autonomy (a lot!), but we have a strong team that’s always available to help.

This is an on-site position in our Paris office (9em) with flexible remote work allowed a few days per week. None of the people who joined Sifflet perfectly matched the described requirements for the role. If you’re interested in this position but don’t tick all the boxes above, feel free to apply anyway!
