Senior Software Engineer, AI Agents

Stackd; 's-Hertogenbosch; Hybrid; EUR 90,000 - 150,000; Full time

Job summary

IFS is seeking hands-on engineers to build the intelligence behind AI-powered experiences. You will shape session memory, retrieval across manuals and documents, and multi-step agentic flows that operate on real systems with real users.

You will work with Go and Python in production, focus on latency and cost, and collaborate with DevOps, security, and data teams to deliver scalable AI-native solutions across tenants.

Qualifications

• Experience with S2S integration using tools like n8n, Temporal, MuleSoft, Apache Camel, or Boomi.
• Production backend experience with Go and Python; specifics on scale and traffic preferred.
• Experience building multi-tenant SaaS on shared infrastructure.
• Experience with production-grade GenAI solutions, including RAG pipelines.
• Familiarity with AI frameworks and tooling such as LangChain and MCP.
• DevOps and cloud-native infra knowledge: Docker, Kubernetes, CNCF, CI/CD.
• Experience with API gateways, ideally Kong or Tyk, is a plus.
• Focus on latency, cost optimization, and specification-driven development.

Responsibilities

• Build session and memory models, retrieval across documents and own estate.
• Design agentic flows for multi-step tasks and tool usage.
• Implement evaluation harness to gate autonomy claims.
• Create language interfaces over scheduling and optimization engines.
• Ensure security, data residency, and guardrails with the security team.
• Support multi-tenancy and scalable AI-native product development.
• Collaborate across teams to deploy production-grade AI services.

Job description

Before you apply

This is a hands‑on production role, not a research or prototyping one. Please only apply if you've personally built or been a core builder on a system that's live with real users — not a demo, hackathon, or personal project.

You should be able to speak in depth, from direct experience, to most of the following:

• You've built an agent or LLM system that takes actions against business systems — calls APIs, updates records, triggers workflows — not one that only answers questions from documents.
• You've shipped Go (or Java or similar languages) in a production backend (be specific about which, and how much).
• You've worked with a service-to-service orchestration tool such as n8n, Temporal, MuleSoft, Apache Camel, or Boomi.
• You've operated an API gateway (Kong, Tyk, or similar) in production.
• You've built or run a system serving multiple tenants/customers on shared infrastructure.
• You've built or used an evaluation framework to validate AI output quality before it shipped — not just spot‑checked it.

If your AI experience is mainly demos, personal projects, or wiring a single LLM call into an app, this role is above that level.

Our leading AI technology is the backbone of our award‑winning enterprise software solutions, enabling our customers to be their best when it really matters–at the Moment of Service™.

If you want to change the status quo, we’ll help you make your moment. Join Team Purple. Join IFS.

Job Description

Build the intelligence behind the experience: the session and memory model, retrieval across our own estate and the documents that run it, the agentic flows that carry out multi‑step work, and the evaluation that tells us whether any of it is right.

What you will do

• Build the session and context spine: persistence, resumption, hand‑over with the reasoning trail intact, and context resolved from a person's identity and entitlements.
• Build retrieval and grounding across structured records and documents, at a cost and latency the product can afford.
• Build document intelligence over manuals, engineering drawings, certification directives and contracts, extracted and citable, because for many of our customers those carry as much operational truth as the databases.
• Build the agentic flow runtime: multi‑step work with tools, and the rules that decide when a human is asked rather than told.
• Handle speech and images as first‑class input alongside text, so the same request works dictated in a plant room or photographed at an asset.
• Build the evaluation harness, and treat it as the gate on every claim we make about autonomy.
• Build the language interface over our scheduling and optimisation engines, expressing trade‑offs in the customer's own terms.
• Build the security layer with our security team: resistance to prompt injection, personal data handling, guardrails, audit and data residency.

Qualifications

Experience with S2S integration, preferably using technologies such as n8n or Temporal, or alternatively MuleSoft, Apache Camel, or Boomi.

• Experience with Go and Python.
• Experience building multi‑tenant SaaS solutions.
• Experience building and scaling AI‑native products and applications.
• Experience with production‑grade GenAI solutions, including RAG pipelines (hybrid retrieval, embeddings) and agentic systems (agent orchestration, tool usage).
• Experience with AI frameworks and tooling such as Pydantic AI, LangChain, and MCP.
• Experience with MCP development and plan‑based agentic software development.
• Experience with DevOps and cloud‑native infrastructure, including Docker, Kubernetes, CNCF technologies, and CI/CD pipelines.
• Experience with API gateways and API products, preferably with platforms such as Kong or Tyk.
• Preferably experience optimizing AI services for latency and cost.
• Preferably experience with specification‑driven development.
• Passionate about and eager to adopt new technologies.
• Up to date with the latest developments in GenAI and AI‑based software development.
