We are looking for you!

We’re looking to invite talented Design Researchers—from promising Mid-levels to accomplished Seniors—into our freelance talent network. This is not a full-time position — instead, once selected you become part of our vetted pool of freelancers, and we’ll reach out whenever relevant projects arise. You’ll be engaged on a project basis, supporting or leading user research, uncovering deep insights, and translating user needs into actionable strategies for physical and digital products and experiences. If you thrive on talking to users in their own environments, connecting the dots, and championing human-centered design in flexible, interesting assignments — we want you.

What impact you’ll make

• You’ll help ground high-quality digital experiences and innovations— spanning health tech platforms, automotive HMIs, and cutting-edge product concepts — in real human needs, working with globally recognized brands.
• You’ll uncover hidden user behaviors and needs by stepping out of the office and into the field, bringing deep contextual empathy back to the project team.
• On each project you’ll collaborate with designers & strategists to bring creative insight and validation — from early-stage discovery through to evaluative testing — helping turn the brief into a validated reality.

At N-iX CTO Group, we harness the power of technology to drive innovation and deliver exceptional business value.

Join a vibrant team committed to driving large-scale transformation across global enterprises.

As an Engineering Manager at N-iX, you will play a key leadership role in guiding our partners through digital transformation, application modernization, and other large-scale technology programs. You will oversee engineering delivery across multiple engagements, ensuring our teams deliver exceptional technical outcomes and business value.

This role is ideal for a seasoned technology leader with a strong consulting mindset, the ability to manage complexity, and a passion for building high-performing teams that help clients succeed in their most critical initiatives.

Key Responsibilities:

• Act as a trusted advisor to client technology executives (CIOs, CTOs, Heads of Product/Innovation).
• Shape and steer digital transformation and modernization programs in partnership with clients.
• Translate business goals into technology strategies, roadmaps, and execution plans.
• Lead engineering execution across multiple accounts and initiatives, ensuring scalability, security, and performance.

• Experience building and scaling high-performing, distributed engineering teams.
• Excellent leadership, communication, and strategic thinking skills.
• Experience in transportation, logistics and enterprise resource planning as a plus.

About the project:

Every client engagement starts with a question: can we actually build this, and how? This role sits at that exact moment — leading technical discovery and pre-sales across multiple prospective and active engagements at Glorium. You’ll turn ambiguous client challenges into concrete solution designs, realistic estimates, and architectures that delivery teams can actually execute. The work spans Node.js and .NET backends, React/Angular front-ends, and an increasing share of AI/LLM integration — RAG pipelines, agentic workflows, orchestration, and guardrails.

A new team member will be in charge of:

• Lead discovery and scoping sessions end-to-end — from the first client call to a signed-off solution design, proposal, and effort estimate.
• Own the architectural output: high-level and detailed diagrams, data flows, integration patterns, and trade-off decisions that delivery teams inherit and build on.
• Design AI/LLM integration patterns — RAG, agentic workflows, orchestration, guardrails — and factor AI-accelerated delivery into estimates from the start.
• Act as the primary technical voice with clients during pre-sales: demos, presentations, PoCs, and the credibility that moves deals forward.

• Mentor delivery teams on architecture decisions and applied-AI best practices, keeping quality consistent across engagements.

   

Does this relate to you?

• 7+ years in software development, with at least 2 years in an architectural role that included real pre-sales or client-facing solutioning — not just internal design work.
• Hands-on expertise in Node.js and/or .NET system architecture; you can design scalable, secure, maintainable systems and explain every trade-off you made.
• Proven ability to produce clear architectural diagrams and data flows — the kind delivery teams can pick up without a lengthy handover call.
• Comfortable running discovery and scoping sessions solo: translating vague business requirements into structured solution designs and realistic estimates.
• Strong practical experience designing AI/LLM integrations — RAG pipelines, agentic workflows, provider APIs, and governance/guardrail considerations.
• Familiarity with cloud platforms (AWS, Azure, or GCP) and their AI/ML service offerings.
• Upper-Intermediate English or above — enough to present architecture to a non-technical client stakeholder and hold your own in a technical deep-dive with their engineering team.

• React or Angular front-end exposure and availability for occasional client calls between 6–8 PM CET are a strong plus.
