Job description

What you’ll do
As a Python Staff Engineer, you excel in driving coding excellence and you possess deep understanding of design patterns, code quality, and testing frameworks. You are responsible for translating client requirements into functional code, primarily focusing on real-time data processing, storage tools, and integrations from edge to cloud. This includes working with IT network systems and machine learning for remote operations. In addition to coding, you also handle testing and implementation.

Your contributions are most impactful if you possess a working knowledge of analytics solutions and platforms, proficiency in managing PostgreSQL and TimescaleDB systems, and expertise in programming languages next to Python such as C++ and C#.

Additionally, you have experience with any of the following microservices architecture components; Docker, Docker security, moby engine and container CI/CD pipelines, Confluent Kafka or the ability to learn them fast. Experience in Linux and Azure DevOps or other cloud platforms, will further enhance your effectiveness in this role. Familiarity with Grafana and FastAPI is a strong plus.

Note that as Senior level professional, you have a history of technical leadership and are able to explain complex technical concepts to others. This is critical as you will be responsible for reviewing colleagues' coding and ensure highest standard of quality. You live by good coding principles and can coach others to follow them.

Qualifications

Who are you?
Honestly, we don't even need to spell out this role for you. You live it and breathe it. To thrive in this team, it's important to have the seniority, knowledge, skills and experience to guide others in meeting the highest quality coding practices. You are someone who gets a kick out of driving important changes. Someone who leaves a mark!
If you are surely a bit of an expert, and you:

Are a resident of The Netherlands and have a permanent work permit (we do not sponsor visas nor relocations).
Have a bachelor’s or master’s degree in computer science or equivalent and at least 10 years of proven work experience with backend Python development.
Have a solid track record of over 10 years demonstrating mastery of Python, from development/test to production software delivery mainly within the real time data industry.
Possess enhanced skills with other programming languages like C++ and C#.
Have exceptional English communication and people skills, adept at conveying complex technical information to both technical and non-technical stakeholders.

And it would be great if you have experience in a fast-growing scale-up international environment.

This is what you get from us

A chance to be part of an amazing international team.
A flexible work environment; at our growing office in Rijswijk and from home.
The chance to learn, excel in your craft and grow. We will support your education and development with a yearly budget, and you’ll have plenty of freedom for your own ideas and initiative.
Lunch is on us every working day and on Fridays, we get food from one of our favorite local eateries delivered to the office.
We’ve got your commuting expenses covered and we offer a bike plan.
After putting in all effort, we want to make sure you can unwind too. If you work a 40-hour week, you’ll have 24 vacation days, and we will offer you the possibility to work remotely for 2 weeks per year.
We've got your retirement savings sorted too, and Helin covers half of the contribution.
