The team values fresh perspectives, and experience in energy, oil and gas, or industrials is a plus, not a requirement. ## Description We are looking for a CTO and senior technical leader to partner with the technical founder. While the founder owns the core data architecture, he needs a strategic partner to run the engineering organisation, manage investor due diligence, and share the load of key technical decision-making. We are not looking for a duplicate of the founder, but rather the person who can build the ecosystem around him. This is a role for an architect and a team builder who can navigate between strategy and hands-on execution., * Build the team. Your first measurable outcome is hiring autonomous senior engineers who own problems end-to-end. You will define the hiring standards, processes, and organisational decisions in a company that prioritises a small, high-density team. * Run engineering. Establish cohesion and delivery rhythms. From standups to ownership structures, you will implement the durable processes that allow for visibility and consistent output. * Set technical direction. Define the product roadmap for the next 12-24 months, manage the buy-vs-build decisions, and architect support for new verticals, starting with oil and gas. * Be a genuine peer to the technical founder. Engage in deep architectural discussions, challenge assumptions, and reach joint decisions that you both stand behind. * Represent the company. Serve as the technical face of the firm during investor due diligence, enterprise client meetings, and integration discussions, serving as a key point of contact for stakeholders. * Stay in the code. This is a hands-on technical role. You will continue to architect, review, and build alongside the team.
