About Martell Group

The Martell Group exists to build people, brands, and ventures that create meaningful impact. Across our four companies, we combine audience, operators, and execution to launch scalable products and empower ambitious leaders in Media, B2B SaaS, and AI.

Founded by serial entrepreneur and investor Dan Martell (investor in Udemy, Intercom, and Unbounce), we're building a company that values leadership, growth, and simplicity, and we're looking for people who live those values too.

Our goal is to attract world-class talent and align people where their impact is greatest. When you apply to Martell Group, you'll automatically be considered for all open roles across our companies, not just the one you applied for.

Position Responsibilities

Martell Ventures is looking for a highly technical builder and strategic thinker to lead engineering excellence across its growing portfolio of businesses.

This is not a traditional CTO role focused solely on executive oversight. We need someone who can think strategically, challenge assumptions, and get directly involved in the technical work when it matters most.

You will be the technical authority across the Ventures portfolio, helping companies build better products, solve complex engineering challenges, strengthen technical teams, and move faster with modern AI and agentic development.

You'll work closely with Dan Martell, portfolio business leaders, and experienced technology advisors to turn ambitious ideas into practical, scalable solutions.

A significant part of your mandate will be establishing Martell Ventures' technical presence in Waterloo, building a strong local engineering community, and creating the standards that enable our portfolio companies to scale.

This is an opportunity to shape how multiple businesses build, operate, and grow while remaining close to the technology itself.

What You'll Do

Technical Strategy & Architecture

• Evaluate the technical infrastructure, architecture, codebases, and engineering practices across portfolio companies, identifying opportunities to improve quality, security, scalability, and performance.
• Work directly with engineering teams to diagnose technical challenges, improve architecture, and implement practical solutions.
• Establish consistent engineering standards, shared development practices, frameworks, and tooling across the portfolio.
• Drive adoption of modern AI and agentic development practices to improve engineering speed, efficiency, and product delivery.
• Ensure portfolio companies maintain appropriate technical infrastructure, security practices, backups, and operational resilience.
• Help portfolio leaders understand technical risks, opportunities, and priorities so they can make informed business decisions.
• Support technical readiness for future acquisitions, investment opportunities, and potential exits.

Building & Developing Technical Talent

• Establish and grow Martell Ventures' technical presence in Kitchener-Waterloo.
• Help recruit, assess, and develop exceptional engineering talent across the portfolio.
• Partner with portfolio business leaders on technical hiring decisions, including engineering leads and senior technical positions.
• Provide technical guidance and mentorship to portfolio engineering leaders while maintaining a dotted-line relationship with those leaders.
• Establish consistent technical practices, knowledge-sharing, and training opportunities across portfolio teams.
• Develop relationships with the University of Waterloo, Communitech, and the broader Waterloo technology ecosystem to build a sustainable talent pipeline.
• Collaborate with Waterloo-based technology advisors Michael Litt and Marcelo Cortes to strengthen the group's engineering capabilities and local network.

Product Development & Execution

• Translate ambitious business ideas into practical technical plans with clear priorities, realistic timelines, and measurable outcomes.
• Provide hands-on technical support when portfolio companies face complex engineering challenges or execution bottlenecks.
• Evaluate build-versus-buy decisions and help prioritize technical investments based on business value.
• Support engineering teams in delivering reliable, scalable products that meet customer needs.

• Serve as a trusted technical thought partner to Dan Martell and the Ventures leadership team.
• Bring independent technical judgment, including the confidence to challenge ideas, push back on unrealistic commitments, and recommend alternative approaches.
• Help establish a culture of technical excellence, accountability, and continuous improvement.
• Work across multiple businesses and priorities while maintaining a clear focus on the highest-impact opportunities.
• Communicate technical decisions, risks, and progress clearly to both technical and nontechnical stakeholders.
• Lead by example through a combination of strategic thinking, practical execution, and strong technical credibility.

What matters most is your ability to solve difficult technical problems, raise engineering standards, and build products that work.

• Deep hands-on experience in software engineering, systems architecture, and building scalable production applications.
• Recent, practical experience developing with modern AI technologies, LLMs, agents, and agentic development tools.
• Demonstrated ability to evaluate existing software architecture, identify technical weaknesses, and implement effective solutions.
• Strong technical credibility and the ability to work directly with experienced engineers on complex technical challenges.
• Experience building and shipping software products in startup, scale-up, or similarly fast-moving environments.
• Strong product and business judgment, with an understanding of how technical decisions affect customers, revenue, and growth.
• Experience assessing engineering talent, making technical hiring decisions, and helping build high-performing teams.
• Ability to balance technical quality with speed, pragmatism, and commercial priorities.
• Confidence working with strong founder personalities and challenging ideas when necessary.
• Strong communication skills, with the ability to translate complex technical concepts into clear business recommendations.
• High ownership, adaptability, and comfort operating across multiple businesses with changing priorities.

Preferred:
