The posting

Location: Madrid, Spain (Remote — with regular in-person collaboration at a local WeWork alongside our Madrid tech team)

About MediaRadar:

MediaRadar, now including the data and capabilities of Vivvix, powers the mission-critical marketing and sales decisions that drive competitive advantage. Our competitive advertising intelligence platform enables clients to achieve peak performance with always-on data and insights that span the media, creative, and business strategies of five million brands across 30+ media channels. As we expand our footprint from the US into Europe and deepen our focus on media intelligence, we're looking for engineers who can help scale our platform and products globally.

About the Role:

We're looking for a Senior Software Engineer to independently own complex, ambiguous problems across our platform. You'll design, build, and scale systems that power MediaRadar's competitive advertising intelligence platform — with a particular focus on developing agentic, AI-driven capabilities that deliver customizable insights to our clients.

Stack Highlights:

Core: Strong Python proficiency is a must; comfort with additional languages (C#, Java, Node.js) a plus.

Cloud: Hands-on experience with AWS and/or Azure is a must.

Data: SQL (SQL Server, Postgres), with Databricks/ETL experience a plus.

AI/Agentic: Experience with LLM-powered or agentic systems (LangChain, multi-agent orchestration, RAG) is highly valued.

Productivity: Use of modern AI coding assistants (Copilot, ChatGPT) to accelerate development.

Requirements

Key Responsibilities:

  • Independent System Ownership: Design, build, and own complex, ambiguous features end-to-end, operating with minimal supervision.
  • Agentic Insights Studio: Lead the buildout of agentic, LLM-powered workflows that deliver customizable, automated insights for end users.
  • Cloud Architecture: Architect and scale cloud-native systems (AWS/Azure) that support our expansion from the US into European markets.
  • Mentorship: Mentor junior engineers and raise the technical bar across the team through code reviews and shared best practices.
  • Engineering Excellence: Drive testing, observability, code quality, and documentation standards across your area of ownership.
  • Cross-Functional Partnership: Partner with Product, Data, and Operations to shape technical roadmap and integration strategy across the MediaRadar/Vivvix data platforms.

Key Qualifications:

  • Experience Level: 4–6+ years of professional software engineering experience (Senior level).
  • Python: Expert-level Python is required; comfortable owning production systems end-to-end.
  • Cloud: Proven experience architecting and operating systems on AWS and/or Azure is required.
  • Agentic/AI Experience: Hands-on experience building LLM-powered or agentic systems (LangChain, multi-agent orchestration, RAG) is very strongly preferred.
  • Industry Relevance: Background in adtech, advertising, media intelligence, analytics, or sports-media data is highly valued.
  • Global Scope: Comfortable working across distributed, international teams as we expand from the US into Europe.
  • Software Rigor: Strong grasp of architecture and design patterns, with a track record of mentoring other engineers.
  • Professional fluency in written and spoken English: Strong communication skills to effectively collaborate with distributed engineering, product, and business teams across North America, India, and Europe.

Skill Focus for 2026/2027:

  • Agentic Insights: Building and scaling AI-driven, customizable insight generation for our Insights Studio product line.
  • Global Expansion: Ensuring platform scalability and reliability as MediaRadar expands from the US into European markets.
  • Sports & Media Intelligence: Extending our data and attribution capabilities into sports-focused advertising and media verticals.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
