Lediga job som IAM-specialist

We build AI agents that audit and optimize e-commerce advertising. Our platform syncs live data from Google Ads, Meta, Merchant Center, and Google Analytics, runs it through a rule engine, LLM-powered audit agents, and our own prediction models, and turns the findings into concrete actions marketers can apply with one click.

We're a small team shipping fast on a modern, strictly-typed stack. You'd be one of a handful of engineers reporting directly to the CTO, which means real ownership: features you design end-to-end, from the Prisma schema to the React component, ship to customers within days.

• Design and build features across our TypeScript monorepo — tRPC procedures and NestJS services on the backend, React on the frontend.

• Extend our integration workers that sync campaign, product, and analytics data from the Google and Meta APIs via Cloud Pub/Sub pipelines.

• Work on the AI audit agent: prompt design, rule evaluation, and the plumbing that turns LLM output into reliable, deduplicated actions — across multiple model providers, not just one.

• Help productionize our in-house prediction models: wiring their output into the rule engine and keeping training data and evaluation pipelines healthy.

• Evolve the data model in PostgreSQL/Prisma and keep migrations, multi-tenancy, and role-based access clean as the product grows.

• Own quality: write Jest tests alongside your code, review PRs, and help keep our CI/CD pipeline to Cloud Run fast and boring.

• 5+ years building production web applications, with strong TypeScript on both server and client.

• Solid relational database instincts — schema design, migrations, and query performance in PostgreSQL (Prisma experience is a plus).

• Experience with event-driven or queue-based architectures (Pub/Sub, SQS, Kafka, or similar) and the failure modes that come with them.

• A habit of testing: you write tests because they let you move faster, not because someone told you to.

• Pragmatic product sense — you ask why before how, and you'd rather ship a focused feature than a perfect abstraction.

• Hands-on work with LLM APIs in production — prompting, evals, structured output, cost control, and switching between providers.

• Applied ML experience: training, evaluating, or serving prediction models alongside product code.

• Familiarity with the Google Ads, Meta, or Merchant Center APIs, or ad-tech / e-commerce domain experience.

• NestJS, tRPC, or GCP (Cloud Run, Artifact Registry, Workload Identity) in a previous role.

Small team, short feedback loops, no ceremony for ceremony's sake. Strict TypeScript, code review on everything, CI that deploys to Cloud Run on merge. We optimize for shipping value to customers weekly and keeping the codebase a place people enjoy working in.

What will you do?

As a Senior .NET Developer who not only loves solving complex problems but is passionate about code quality, and building scalable and testable solutions.

You’ll be adequately self going, contribute to technical discussions, and aspire to deliver clean, robust code. You have a sharp eye for simplicity amidst complexity and pride yourself on thorough, thoughtful development, including writing tests for critical components. Whether working closely within your team or leading a project area independently, you’re confident, collaborative, and proactive.

Areas of ownership:

• Take part the design, development, and deployment of complex, high-throughput backend services and APIs, ensuring best-in-class performance and maintainability.

• Establish and articulate a clear, ambitious long-term vision and technical roadmap for the evolution of the BE systems.

• This includes planning for future growth, anticipating technological shifts, and driving the adoption of new technologies and patterns to maintain a competitive edge.

• Proactively identify and resolve technical debt before they impact the business.

• Mentor engineers, elevating the technical expertise and quality of engineering output across the organization.

• Influence engineering standards and best practices for testing, performance tuning, and security across different development teams.

Requirements

• Exceptional and proven proficiency in the .NET area, including extensive experience with C#, .NET Core/5+, and related frameworks (e.g., ASP. NET Core, Entity Framework Core).

• Demonstrable architecting skills with a strong background in designing and implementing large-scale, distributed systems (e.g., microservices, event-driven architectures, serverless).

• Expert knowledge of design patterns, domain-driven design (DDD), and SOLID principles.

• Extensive experience with at least one major cloud platform (AWS, Azure, or GCP) and related services (e.g., managed databases, message queues, containerization).

• Deep understanding of various database technologies (SQL and NoSQL) and data modeling best practices for scalable applications.

• System-Level Thinking: Ability to decompose complex problems into manageable components and evaluate trade-offs between different technical solutions (e.g., speed vs. stability, buy vs. build).

• Excellent verbal and written communication skills, with the ability to present complex technical ideas clearly to both technical and non-technical stakeholders, driving consensus on critical architectural decisions.

Why Rebtel?

Rebtel has been connecting people across borders for nearly 20 years. Today, we’re profitable, growing, and at a pivotal moment in our journey.
