Software Engineer

We are Adnami, a Danish AdTech scale-up that is changing the digital media landscape. Since 2019, we have been helping brands and agencies run campaigns that actually get noticed (we act with attention!).

We are growing fast (well, really fast), and now we are looking for a mid-level or senior Software Engineer to join the Core team in Copenhagen. The team responsible for the browser runtime, APIs, data pipelines, and infrastructure behind our ad platform. Is that you?

The role The Core team owns the systems end-to-end: browser runtime, APIs, ETL pipelines, data systems, and infrastructure. This is revenue-critical infrastructure. When something breaks or degrades, it affects campaign delivery and measurement directly, the feedback loop is short. Recent examples of problems the team has worked on:

• Share of Voice — high-impact formats expand and fill the viewport gradually, so we redesigned how we sample screen real estate over time to reflect the true presence of a format rather than a single moment
• In-app measurement — advertisers increasingly care about in-app environments, so we extended our measurement coverage there by integrating with the industry-standard OMID API
• ETL performance — as event volumes grow, our data pipelines need to keep up; we've been optimising throughput and resource efficiency so the data our customers and internal teams rely on stays timely and reliable
• Resilient global infrastructure — our Geode API serves requests globally, and we've been hardening it with health checks and self-healing behaviour so it stays up without manual intervention
• Safe rollout of a major API change — we revamped a core piece of browser runtime used across the web, and had to figure out how to ship that without disrupting live campaigns
• Cross-format engagement measurement — video and audio formats behave very differently at runtime, and we're working to make sure our measurement of engagement and viewability is consistent and meaningful across all of them

The problems range from measurement logic and system performance to careful release engineering and platform integration. Operational work, debugging production issues, improving observability, addressing reliability, is part of the job too, but it is not the majority of it.

How we work We are a small engineering team. Engineers are expected to understand the systems they work on broadly, participating in technical decisions, helping shape solutions together with product and commercial teams, and owning systems in production, not just implementing isolated tickets.

We work in Shape Up cycles: six-week development periods with a defined scope and no rolling backlog, followed by room for iteration, cleanup, and technical improvements. Engineers work closely with product and commercial teams when deciding what problems are worth solving next. There is very little organizational distance between an engineering decision and its impact on customers.

Our stack

• .NET / C#
• JavaScript / TypeScript
• Azure
• Snowflake
• Infrastructure-as-code

Experience with all of these is not required. We care more about strong engineering fundamentals, ownership, and the ability to reason about systems.

You will probably enjoy this role if you

• Like understanding systems broadly, from browser behavior to APIs, pipelines, and data
• Care about correctness, reliability, and data quality
• Are comfortable owning systems in production, including infrastructure and deployments
• Prefer pragmatic solutions over unnecessary complexity
• Do not mind diving into browser quirks, edge cases, and operational details when the system demands it
• Like working closely with other engineers to improve systems together

What we offer

• Competitive Salary
• Lunch scheme
• Birthday Day Off
• Referral Program
• A fast-paced environment
• Flexible working environment where the results are what matters
• Mobile phone & home internet paid
• A young and dynamic workplace
• A lovely office in central Copenhagen
• A warm and friendly atmosphere where we work hard together but also enjoy each other's company, not seldom with a drink in hand on Fridays.
