Backend Engineer @ umanitek

Opis delovnega mesta

The Umanitek Guardian Agent protects people from deepfakes and digital impersonation by combining Decentralized Knowledge Graphs (DKG) with perceptual intelligence. If you are excited by the idea of building resilient infrastructure and operational systems for agents that reason, not just predict, you will feel right at home.

As a Backend Engineer, you'll work on the Guardian Agent server-side architecture which includes the backend services, REST APIs, and plugins that power them. You will contribute directly to building the microservice architecture from the ground up, develop MCP based agent tooling, and transform AI-driven capabilities into reliable, production-ready products.

You will spend a significant portion of your time building and extending the REST APIs and MCP tools utilized by the Guardian agent, while also making sure that all the proper security, scalability and maintainability principles are always in place.

This is a hands-on role where ownership, architectural thinking, and the ability to move fluidly between responsibilities really matter.

Od kandidatov zahtevamo

Technical experience:
- 4+ years of professional software development experience in a backend engineering role
- Strong experience with TypeScript across backend services
- Experience building backend services with Node.js, Express and Nest.js
- Experience with LLM systems/applications and the Model Context Protocol (MCP)
- Familiarity with REST APIs, authentication flows, and event-driven or agent-based systems
- Experience working with APIs, automation, scripting, and API/SDK integrations
- Experience with relational databases and ORMs (TypeORM/Prisma/Drizzle)
- Comfort working across repositories and collaborating in interdisciplinary teams
- Strong communication skills and a product-oriented mindset

Technical experience that is nice to have:
- Strong experience with Nest.js framework
- Experience with cloud computing services (AWS/GCP)
- Experience working with Decentralized Knowledge Graphs, semantic web, or graph data
- Familiarity with Web3 / blockchain concepts (wallets, signatures, decentralized infrastructure)
- Experience with automation pipelines or agentic workflows
- Basic familiarity with Turborepo build system

O podjetju

Umanitek is a Swiss AI and data infrastructure company building systems to reduce AI-driven harm at scale. We operate at the intersection of large language models, social platforms, and digital identity, focusing on risks that cannot be solved by any single platform alone, hallucinations, impersonation, coordinated abuse, and content misuse, while preserving privacy and jurisdictional boundaries.

Our core product, the Guardian Agent, continuously monitors how individuals, brands, and organizations appear across LLMs and social platforms. It detects misrepresentation, fake accounts, deepfakes, and coordinated narrative attacks, computes live risk scores, and generates cryptographically verifiable evidence showing when content appeared, how it spread, and how it evolved. Guardian runs on decentralized infrastructure that allows platforms and institutions to signal and verify harmful content without sharing raw data, enabling fast takedowns, corrections, and enforcement without compromising privacy or competition.

Zakaj bi želel delati za vas

We are solving problems that are technically hard and structurally unsolved: hallucinations, impersonation, coordinated abuse, and misinformation embedded directly into AI systems, where privacy, jurisdiction, and scale actually matter. You work with people who have already built companies and shipped complex systems, in an environment with high standards, real ownership, and freedom to push ideas into production. You shape the product, the architecture, and the direction of the company from day one. Think American-scale ambition, built in Europe, with the goal of defining how AI safety is actually done.
