Senior AI Agentic Engineer

Job Summary:

The Senior AI Agentic Engineer, based in Athens, Greece, bridges both worlds — owning the product vision and roadmap for Profile One, while leading the technical architecture of our AI projects. This is a hybrid role for someone who thinks in products and builds in systems, equally comfortable defining what gets built and getting into the detail of how it works.

• Own the architecture of the Group's agentic platform: orchestration patterns (supervisor / sub-agent), agent decomposition, tool-calling design, memory and state management, error handling and human-in-the-loop integration.
• Lead implementation across the agent framework stack — Lang Graph, Lang Chain or equivalent — with a strong opinion on framework choice and lifecycle.
• Design integration patterns with our systems of record, with primary focus on read-side integration via the SQL / T-SQL output layer.
• Define and operate the evaluation layer — golden datasets, regression suites, agent-level metrics and human review workflows for non-deterministic outputs.
• Own the observability and tracing stack (Langfuse, Cloud Watch) and the runtime quality, latency and cost envelope of the platform.

• Lead the in-house agentic engineering team (Agent Developer, Data Engineer) with technical mentorship, code review.
• Manage the relationship with our external delivery partner during the PoC phase; define the transition plan from external-led delivery to internal ownership of core capability.

• Partner with our operations team and with Group commercial leads to convert client demand (process automation, reconciliation, exception handling, communications) into deployed agents.
• Translate operational process descriptions into agent designs — including with input from Business Analysts and operations subject-matter experts.
• Own production readiness: SLOs, security review, regulatory alignment (DORA, MiFID II, GDPR, NIS2), and acceptance criteria for client-facing pilots.

• Work alongside the Profile One Product Manager on the architectural separation between unifying layer and agentic platform.
• Partner with the AWS infrastructure / Dev Ops function on production deployment, scaling and security hardening.
• Represent the agentic platform in client technical discussions, internal Steer Co updates and Group-level architectural reviews.

What You Will Bring:

• 8+ years in software engineering, including 3+ years actively building production systems on top of LLMs or agentic frameworks (not only experimentation or prototyping).
• Strong experience in the banking and wealth management domain, with understanding of financial products, investment workflows, portfolio management, client servicing, and the operational and regulatory constraints of financial institutions.
• Hands-on, recent experience with at least one agentic framework — Lang Graph, Lang Chain, Auto Gen, CrewAI, or comparable — including supervisor / multi-agent patterns.
• Strong AWS engineering background (Bedrock, Lambda, S3, IAM, Cloud Watch); production operating experience on AWS-native AI/ML stacks.
• Demonstrated experience designing evaluation frameworks for non-deterministic AI outputs: golden datasets, regression testing, human review workflows, agent-level metrics.

What We Offer:

• Competitive and performance-based remuneration.
• Meal Vouchers.
• Medical & Life Insurance Plan.
• New experiences within a multinational environment and global teams.
• Team spirit environment with passion for technology.
• Development opportunities within a market-leading, fast-growing organization!
