We are QUALCO, the technology arm of Qualco Group, with over 25 years of experience in delivering innovative solutions to the financial sector. We serve clients in over 30 countries, helping banks and other financial institutions manage credit and loans effectively while ensuring full regulatory compliance. Our advanced software leverages analytics, artificial intelligence, and digital technologies to support every stage of the credit and lending lifecycle, remaining at the forefront of fintech innovation.The FDE is the person who writes the production code that makes an AI/ML use case real, and who feeds what they learn back into the Core platform so the next deployment starts from a stronger baseline than the last. This is the same field-to-platform feedback loop Palantir calls "gravel road to paved highway".How your time breaks down:Full-stack AI/agent development — writing production code, building integrations;Enterprise architecture design — deciding how the solution fits the client's real systems and constraints;Strategic client discovery — understanding the client's workflows well enough to know what's actually worth building.What you'll actually do:Own the full lifecycle of a deployment: customer discovery, scoping and solution architecture, POC sprint, and the transition from POC to production;Design and build production-grade AI agent systems — RAG pipelines, agent and multi-agent orchestration, tool/harness engineering — against real client data and infrastructure, not synthetic demos;Select and justify the right architecture and framework for each use case, with clear trade-offs communicated to both technical and non-technical stakeholders;Partner with the AI Strategist to translate discovered use cases into a scoped delivery plan, and jointly define what "resolved" means for each engagement;Build long-term relationships with the client and proactively surface new deployment opportunities across the engagement — this overlaps deliberately with the AI Strategist's remit; both roles are expected to keep finding what's next;Navigate real enterprise constraints — legacy systems, messy data, integration limits, compliance requirements — and still ship something that works;Identify and codify repeatable deployment patterns, escalating them to the AI Studio Core team as candidates for reusable platform capability rather than solving the same problem from scratch each time;Support the system through pilot evaluation and into full production, incorporating user feedback along the way;Work on-site with client build solutions e2e;Ensuring that all activities and duties are carried out in full compliance with regulatory requirements and supporting the continued implementation of the Group Anti-Bribery and Corruption Policy.What you're not:Not a solutions engineer who demos and hands off to someone else;Not a one-off contractor — you own the outcome through to production and stay accountable for it working in the real world.RequirementsStrong software engineering, machine learning, or AI infrastructure background — comfortable building production systems, not just prototypes;Working knowledge of RAG pipelines, agent/multi-agent architectures, and orchestration frameworks (e.g., LangGraph);High agency and comfort navigating ambiguity inside a complex organization; high cooperation mindset, low ego, able to balance competing priorities with integrity;Strong communication skills — able to conduct discovery with clients and convey technical trade-offs to both engineers and business stakeholders;Former technical founders and early startup employees are encouraged to apply;A background in financial services / banking operations is a strong plus, though the deep domain literacy requirement sits primarily with the AI Strategist;Greek fluency required for client-facing work; English for internal/Core team communication;Primarily on-site with the client; some travel between client sites and Core team HQ expected.Success in the first 90 days:Delivered a working POC for the first engagement, built on real client data;Successfully transitioned at least one POC toward production, incorporating pilot feedback;Identified at least one implementation pattern worth escalating to the Core team.Success ongoing (quarterly):At least one deployment moved from POC to live production;Demonstrable reduction in build effort versus the previous deployment — evidence the architecture is compounding rather than starting from scratch each time;At least one new opportunity surfaced with the client and shared with the AI Strategist / GTM.BenefitsYour Life @ Qualco GroupAs a #Qmember, you will live out every day in a truly human-centred culture, based on mutual respect, trust, and cooperation.

The FDE is the person who writes the production code that makes an AI/ML use case real, and who feeds what they learn back into the Core platform so the next deployment starts from a stronger baseline than the last. This is the same field-to-platform feedback loop Palantir calls "gravel road to paved highway".
How your time breaks down:
- Full-stack AI/agent development — writing production code, building integrations;
- Enterprise architecture design — deciding how the solution fits the client's real systems and constraints;
- Strategic client discovery — understanding the client's workflows well enough to know what's actually worth building.
What you'll actually do:
- Own the full lifecycle of a deployment: customer discovery, scoping and solution architecture, POC sprint, and the transition from POC to production;
- Design and build production-grade AI agent systems — RAG pipelines, agent and multi-agent orchestration, tool/harness engineering — against real client data and infrastructure, not synthetic demos;
- Select and justify the right architecture and framework for each use case, with clear trade-offs communicated to both technical and non-technical stakeholders;
- Partner with the AI Strategist to translate discovered use cases into a scoped delivery plan, and jointly define what "resolved" means for each engagement;
- Build long-term relationships with the client and proactively surface new deployment opportunities across the engagement — this overlaps deliberately with the AI Strategist's remit; both roles are expected to keep finding what's next;
- Navigate real enterprise constraints — legacy systems, messy data, integration limits, compliance requirements — and still ship something that works;
- Identify and codify repeatable deployment patterns, escalating them to the AI Studio Core team as candidates for reusable platform capability rather than solving the same problem from scratch each time;
- Support the system through pilot evaluation and into full production, incorporating user feedback along the way;
- Work on-site with client build solutions e2e;
- Ensuring that all activities and duties are carried out in full compliance with regulatory requirements and supporting the continued implementation of the Group Anti-Bribery and Corruption Policy.
What you're not:
- Not a solutions engineer who demos and hands off to someone else;
- Not a one-off contractor — you own the outcome through to production and stay accountable for it working in the real world.
Requirements
- Strong software engineering, machine learning, or AI infrastructure background — comfortable building production systems, not just prototypes;
- Working knowledge of RAG pipelines, agent/multi-agent architectures, and orchestration frameworks (e.g., LangGraph);
- High agency and comfort navigating ambiguity inside a complex organization; high cooperation mindset, low ego, able to balance competing priorities with integrity;
- Strong communication skills — able to conduct discovery with clients and convey technical trade-offs to both engineers and business stakeholders;
- Former technical founders and early startup employees are encouraged to apply;
- A background in financial services / banking operations is a strong plus, though the deep domain literacy requirement sits primarily with the AI Strategist;
- Greek fluency required for client-facing work; English for internal/Core team communication;
- Primarily on-site with the client; some travel between client sites and Core team HQ expected.
Success in the first 90 days:
- Delivered a working POC for the first engagement, built on real client data;
- Successfully transitioned at least one POC toward production, incorporating pilot feedback;
- Identified at least one implementation pattern worth escalating to the Core team.
Success ongoing (quarterly):
- At least one deployment moved from POC to live production;
- Demonstrable reduction in build effort versus the previous deployment — evidence the architecture is compounding rather than starting from scratch each time;
- At least one new opportunity surfaced with the client and shared with the AI Strategist / GTM.
