Senior software engineer

Salary Competitive

On-site | Copenhagen, Denmark

Intro

At Tembi, we make sense of complexity. Our platform turns vast amounts of e-commerce data into insights that help businesses grow. We build technology that powers smart decisions, and we do it in a workplace where collaboration and ownership matter.

Join us, and you’ll be part of shaping new ways of how companies access and use big data, while working with people who enjoy solving hard problems together.

About the role

We’re looking for Senior Software Engineers to join our core engineering team. In this role, you’ll be key to building and scaling Tembi’s data collection engine and web scraping technology. Working in a small, agile group, you’ll collaborate with engineers, product managers, and designers on projects that sit at the heart of our platform and directly shape the customer experience.

We are a tight-knit team of 20 people (10 developers), and everyone has a big impact. We value engineers who understand business context, collaborate across functions, and take full ownership of their work. You’ll work closely not just with engineers, but also with Customer Success and Product specialists to ensure we deliver real customer value.

What you'll be doing

As a Senior SW engineer you will:

Develop and improve our data-collection platform for large-scale scraping and ingestion
Design and run ETL jobs to process, clean, and structure massive datasets
Continuously improving data quality, security, and reliability
Innovate new ways to scale and strengthen our platform
Design clean APIs and microservices (REST/gRPC) and applying domain-driven design (DDD) principles
Build event-driven systems using messaging/streaming platforms (e.g., Azure Service Bus, Kafka, RabbitMQ)
Implement infrastructure as code (Azure Bicep) and explore serverless architectures where it makes sense
Ensure robust security in our cloud infrastructure and data pipelines, including access management and isolation of customer data
Participate in system design and architectural decisions
Support and mentor mid-level engineers

Collaborating with product and customer-facing teams to align on impact and roadmap.

What you bring

You'll thrive in this role if you have:

6-10+ years of experience in software engineering
Strong backend development and system design experience
Proficiency in modern programming languages (e.g., Python, TypeScript)
Experience with cloud platforms (Azure, AWS, or GCP) and Docker/container orchestration
Solid understanding of databases (SQL/NoSQL), caching, and streaming/messaging systems
Familiarity with ETL workflows, data modelling, and large-scale data processing
Experience designing APIs, microservices, and event-driven architectures
Familiarity with Infrastructure as Code (Bicep, Terraform)
Experience with CI/CD, testing strategies, and DevOps tooling
Strong collaboration skills and ability to work across disciplines
Security-first mindset - experience with cloud security, identity & access management, and protecting customer data at scale
Experience with observability and reliability (Grafana, tracing, logging, alerting)
Business awareness - you think in terms of customer and product impact, not just code

Huge plus if you have:

Familiarity with AI/ML concepts and hands-on experience delivering AI-powered features
Familiarity with Selenium/Scrapy frameworks
Background in data-intensive systems, large-scale scraping, or data pipelines
Experience in high-growth startup or scale-up environments
Ability to align technical solutions with business strategy and contribute to roadmap planning

Tembi is a platform that helps companies use open data about markets and companies to focus their strategy and implement it in the daily routines. Many companies are now able to use their own data about their customers and sales processes etc. (business intelligence). But accessing and using the vast amounts of data from the world outside is much more difficult. Most companies don't have the competencies to do it. That makes it difficult for these companies to act optimally in a dynamic world with uncertain information. We help solving this problem. We collect and combine vast amounts of data from different sources and countries. We apply economic impact models and advanced analytics to solve business critical questions for our customers, such as which markets should they focus on, where is the next big client for us, what do we need to do to be competitive? Our dashboard based solution is easy to use and enables everyone from C-level to the floor to act more efficiently. Come work with us! 👋 We are currently around 20 people in the Tembi team, mostly working within Business Development & Sales and Product Development. But will be growing even more over the coming months. Our office is located in Fiolstræde, right in the heart of Copenhagen. We do a lot of social activities together, and always try to celebrate our success in some way. We have one monthly social activity, such as sports or escape room etc. And we also have summer parties, christmas parties and a friday bar with a different theme every month. When the circumstances require it, we can of course work remotely, but we generally like working together in the office - and we have a super nice lunch every day. Our company culture is based on four pillars. This is who we are: - Inspiring friends - Agile ignitors - Confident navigators - Curious enthusiasts
