Job description

Paiblock, the world’s oldest blockchain company, building enterprise-grade digital currency infrastructure since 2011, is currentlylooking for a GenAISpecialist, that can help shape the next generation of digital customer experiences in crypto payment processing.

We currently repurposing our GenAI-powered assistant from a strong conversational experience into a more personalized, connected, and action-oriented AI product.

You will be central to that journey: designing, building, evaluating, and operating AI systems that can use internal knowledge and APIs responsibly to help customers get the right guidance at the right moment.

About the role

As our GenAI Specialist, you will be a hands-on engineer based at our Copenhagen office. You will support technical direction while building production systems alongside the team.

You will work across the full lifecycle of our AI capabilities, from agent design and retrieval to evaluation, monitoring, and continuous improvement.

Your work will include, among other things:

• Designing and building production-grade agentic workflows, including tool and API use, orchestration, context management, grounding, guardrails, and safe fallback or handover paths.

• Integrating AI systems with internal APIs, data sources, and customer journeys, and building reliable data-ingestion, retrieval, and grounding pipelines that enable relevant and personalized support.

• Establishing the evaluation, testing, and observability practices needed to operate reliable AI systems, measuring quality, safety, task completion, latency, cost, and failure modes, and using those insights to support controlled self-improvement over time.

• Setting technical direction and making sound architectural decisions across models, frameworks, data, security, reliability, and platform design.

• Working closely with the Product Owner, engineers, and business stakeholders to turn customer problems into technically credible, high‑value solutions, while raising the team’s technical bar through hands‑on collaboration and knowledge sharing.

We offer

Here are some of the benefits of working at Paiblock:

• An inclusive work environment where everyone is welcome

• Career and development opportunities in a Danish blockchain scaleup

• Possibility of a hybrid workplace

• A health‑promoting workplace with e.g., fitness programs and various sports activities

• Attractive insurance benefits and pension

Who are you?

You are a junior engineer or graduate that is deeply curious about the fast‑moving AI landscape but grounded in the discipline required to ship reliable products. You enjoy building, testing, measuring, and improving systems in production.

You are a true team player who enjoys lifting others and driving shared technical excellence. You are curious, pragmatic, and unafraid to challenge both technical and business assumptions. Switching between hands‑on coding, architectural thinking, and stakeholder dialogue feels natural to you, and you thrive in an international cross‑functional, and hybrid working environment.

You're likely bringing:

• Experience building and deploying agentic systems in production, with hands‑on Python engineering skills. This includes practical experience with patterns such as tool use, orchestration, routing, state management, guardrails, agent harness, and human‑in‑the‑loop flows.

• Experience integrating AI solutions with production APIs, internal data, and business‑critical systems, together with strong knowledge of RAG, retrieval pipelines, embeddings, vector search, and grounding strategies.

• Experience working with databases and data platforms such as PostgreSQL, MongoDB, and Databricks, including deploying, managing, and integrating them in production environments.

• Experience designing AI evaluations, test suites, quality metrics, feedback loops, and production monitoring, including tracing, prompt and version tracking, quality monitoring, latency, cost, and incident analysis.

• Strong cloud and software‑engineering practices, Git, security, and reliable API design.

• Strong communication skills and the ability to explain technical trade‑offs clearly, challenge assumptions constructively, and turn technical complexity into clear guidance for developers and business stakeholders.
