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

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.

- 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.

- 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.

- 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.
