Location: Remote / Flexible

Vainu is a B2B SaaS company with in-house product development. We are building a new generation of firmographics, predicting organizational characteristics better than anyone else. We started out as a tool for B2B sales but as we’ve expanded, our data is nowadays used by our enterprise customers for a multitude of purposes in their core business processes.

We are looking for a Senior Software Engineer fluent in Python. The role offers flexibility to dive into various areas, whether you want to focus on software engineering or explore the world of AI/ML. If you're already experienced in AI/ML, we welcome seasoned veterans in these fields. In either case, you'll be able to work on challenges revolving around a plethora of various sources, and diverse formats including both well-structured and scattered data.

Topics We’ve Worked On Recently:

Designing data pipelines and scalable processing systems for e.g. contact data.
Data extraction from job postings and companies’ financial documents.
Collaboration with official and third-party data providers and enterprise clients.
Using LLMs to identify key decision-makers from company website.
Company similarity models to identify and cluster similar organizations.
AI models to classify companies based on website content.

What You Bring:

Fluency in Python.
Strong communication skills in English. Any Nordic language is a plus.
Enthusiasm for working on data-heavy projects and solving real-world business challenges.
Experience in the technologies we use (Google Cloud, Docker, Kubernetes, MongoDB, Apache Kafka) is a plus but not required.
If you have experience in AI/ML, you’ll find plenty of opportunities to apply and grow that knowledge here.

How We Work:

Proactivity and Initiative: We believe in taking ownership. Whether it’s code, a process, or a project, we strive to leave things better than we found them.
Blameless and Bold: Mistakes happen, and that's okay. What matters is that we learn and grow together, keeping a positive, startup-like “We can do it” mindset.
Honesty and Humor: We value honesty and smart shortcuts that save time without cutting corners – and we keep it fun with a healthy dose of humor (yes, even the inside jokes).
Curiosity and Clarity: We encourage curiosity about how our work affects our users and want you to have the courage to say "no" or "yes" when it counts.
Active and Remote Collaboration: Whether you're in the office or working remotely, we expect active involvement and collaboration to keep the momentum going.

What We Offer:

A tech-driven, impact-oriented environment with the flexibility to shape your own work.
10% of your work time is allocated to personal development: a full day every two weeks, an afternoon a week, or 45 minutes a day—your call.
Flexible remote work policy and a supportive, inclusive workplace.
Opportunities to apply and grow your AI/ML expertise, if you’re interested in the field.
