Our stack

There are a few unique aspects of our stack:

• Applications have direct access to customer databases, so security is extremely important, and we will invest more than the typical startup in this domain
• We use a single-tenant architecture (one separate infrastructure stack per customer), which means automating infrastructure is key to velocity
• we already run machine learning models (ML) in production for anomaly detection, and we’ll have to support more ML-based applications in the future
• We have a wide range of integrations with modern data stack tools from BI, orchestrators to data warehouses which means we use various APIs to build these heterogenous integrations.

We use state-of-the-art technologies to build our platform:

• Kubernetes (mainly AWS EKS clusters, with some GCP deployments too)
• Infrastructure as code with Terraform, applications deployed with Helm
• Applications written either in (modern) Java or Python, to tap into the huge data ecosystem offered by these languages.
• MySQL (running on AWS RDS) for databases
• Frontend is written in Typescript + VueJS
• and a few supporting services: Gitlab CI, Prometheus/Loki/Grafana…

A few projects you could be working on

• Working on an the orchestration framework
• Working on internal or external APIs
• Developing new integrations to Data Warehouse, Data Visualisation, Transformation, or ETL tools
• Adding new data monitoring capabilities to detect data quality issues
• Improving our internal test framework, build system, and backend framework

Preferred qualification

• You have a BS/MS/PhD in a scientific field or equivalent experience with 2 to 5 years work experience
• Good knowledge of SQL and a good understanding of the categories and main tools of the modern data stack. We don’t expect you to know every detail about every tool in every category of course, you will learn the details needed on the job
• Strong knowledge of Object Oriented Programming (Java, Python or Scala)
• Strong knowledge of REST APIs, software design patterns, performance and scale optimization problems
• You value ownership of your projects from design to production, and have a positive and solution-oriented mindset as well as good communication skills
• Comfort working in a highly agile, intensely iterative software development process

Bonus points

• You have experience building SaaS
• You have experience working in (Big) data environment
• You have experience working with a major cloud environment AWS, GCP or Azure

About Sifflet

We are building the world’s best data observability platform to help companies excel at data-driven decision-making. Today half of a data team’s time is spent troubleshooting data quality issues, Sifflet is putting an end to that. Our solution allows data engineers and data consumers to visualize how data flows between their services, define data quality checks, and quickly find the root cause of any data anomaly. Companies such as Datadog and New Relic have improved the productivity of infrastructure teams tenfold. Our goal is to bring the same benefits to data teams. In a few years, every data-driven company will be using a data observability solution, and we want to be the best solution on the market (and of course, we have plans to go well beyond simple “data observability”). We are backed by tier-1 investors and work with customers all across the globe. Our number of clients is growing steadily, and we need to expand our team!
