About Block Labs

Block Labs is a premier technology studio operating at the bleeding edge of Web3, Artificial Intelligence, and iGaming. We don't just ship features; we engineer high-scale, production-grade platforms that power the next generation of digital products.

We are a collective of senior engineers, product strategists, and builders who refuse to compromise on architecture. Whether we are designing autonomous multi-agent AI systems, building decentralized financial infrastructure, or architecting high-frequency iGaming platforms, our standard is excellence.

We move fast, but we build for the long term. If you are looking to work alongside a team that values deep technical expertise, thoughtful system design, and product ownership, Block Labs is where you belong.

About The Role

Block Labs is building an organization where data and AI are core to how decisions are made and executed. We are hiring a Chief Data & AI Officer (CDAO) to own the company’s intelligence layer — spanning data foundations, decision systems, experimentation, and AI-driven execution.

This is an executive role with accountability for how information is captured, validated, and translated into action across the business. The CDAO ensures that leadership operates on consistent, decision-ready signals and that AI systems are deployed as reliable, production-grade infrastructure.

Key Responsibilities:

Metric Definition & Certification

  • Define and maintain canonical metrics used across the business

  • Own metric logic, lineage, and consistency across teams

  • Certify executive- and board-level KPIs

  • Eliminate conflicting definitions and informal reporting

Decisional Reporting & Intelligence

  • Ensure that key metrics are tied to explicit actions and response protocols

  • Design reporting systems that support operational and strategic decisions

  • Maintain clarity around thresholds, ownership, and escalation paths

AI & Agentic Systems

  • Own the roadmap for AI models, agents, and automated decision workflows

  • Ensure AI systems are production-grade, observable, and maintainable

  • Partner with engineering and product to embed AI into core workflows

Organizational Observability

  • Establish end-to-end telemetry across product, growth, payments, risk, and operations

  • Maintain unified event schemas and data contracts

  • Ensure real-time or near-real-time visibility into critical system behaviour

Experimentation & Learning Systems

  • Govern experimentation frameworks, including A/B testing and causal analysis

  • Validate statistical integrity of experiments and model outcomes

  • Track and improve learning velocity through experimentation throughput and time-to-decision

Data, Model & AI Governance

  • Own data privacy, model risk, and AI governance practices

  • Ensure compliance with relevant regulatory and ethical standards

  • Define controls for autonomous and semi-autonomous systems

Technical Leadership

  • Provide strategic oversight to data engineering and AI teams

  • Ensure platforms are scalable, reliable, and fit for real-time decisioning

  • Prioritize leverage, simplicity, and long-term maintainability in system design

About You:

  • Proven experience building production-grade data and AI platforms

  • Comfortable operating at both executive and technical depth

  • Strong judgment around statistical validity, experimentation, and model reliability

  • Experience deploying AI systems beyond pilot stage into core business workflows

  • Values clarity, rigor, and operational impact over volume of reporting or tooling

  • Motivated by building systems that improve decision quality at scale

  • Operates as a peer to other C-suite leaders

  • Partners with product, engineering, growth, and operations to align data and decision systems

  • Represents data and AI integrity at executive and board level

What Success Looks Like

  • Leadership decisions are based on consistent, certified metrics

  • AI systems meaningfully automate or augment decision-making

  • Experiments translate reliably into business action

What kind of culture can I expect?
Mature, mission-driven, and low-ego. We value clarity over noise, outcomes over theatrics, and pace without chaos. If you’re one of the smartest minds in your craft and want to build with other experts, you’ll feel at home here.
