We are looking for a Head of Product (cofounder) to join our early team and lead the product journey of a startup revolutionizing the world of Audit 4.0 and control management for companies.
Who are we?
At Byld, we don’t just build businesses—we create game-changing ventures in collaboration with leading corporations. Since 2017, we’ve been designing, validating, and launching new companies, blending the best of the entrepreneurial and corporate worlds to develop scalable businesses with real impact.
Our latest venture, Ermine, was born from this vision. Built alongside Erhardt, Ermine is a cutting-edge SaaS platform that simplifies and enhances Risk Management, Audit Management, ESG Management, Quality Management, and Regulation & Standards. It centralizes everything in one place, automating evidence collection, ensuring traceability, and increasing operational efficiency—all while saving time, resources, and costs.
Many companies still struggle with manual processes, scattered information, and compliance challenges. Ermine eliminates these pain points by automating evidence collection, ensuring traceability, and increasing efficiency—all while saving time and resources.
Join us in revolutionizing risk and control management for SMEs.
About the Role
We are looking for a Head of Product with the perfect balance between strategic vision and tactical execution. Someone who can design, validate, and ship impactful product experiences while building the foundations of the product function in Ermine.
As our Head of Product, you’ll be both a strategic thinker and a hands-on builder. You’ll design, validate, and ship our first product modules, working directly with founders, strategic partners, and early customers. At the same time, you’ll lay the foundations for our future product organization, building the culture, processes, and practices that will guide Ermine as we scale. Think of it as a zero-to-one product leader who not only shapes the solution, but also prepares the path for the future product organization.
This is a cofounder-level role: you’ll have ownership, influence, and significant equity (10%), with the support of Byld (Spain’s leading corporate venture builder) and Erhardt, a top-tier industry partner.

As Head of Product, you will:
Define and drive the product strategy and roadmap, aligning vision with customer needs, business goals, and market opportunities.
Lead discovery with customers and prospects: test hypotheses, validate modules, and translate insights into product decisions.
Be the voice of the user: deeply understand their problems, and back your decisions with research and data analysis to design solutions that truly address their needs.
Ship our first 3–4 product modules with early customers, ensuring usability, adoption, and measurable impact.
Design and deliver end-to-end user experience, making complex compliance processes simple and intuitive.
Collaborate with engineering and design to move fast from concept to release, balancing ambition with technical feasibility.
Support go-to-market efforts: partner with sales and marketing on product positioning, demos, and adoption strategies.
Measure product performance with data and feedback, iterating quickly to maximize value.
Feel at home using data to make decisions — whether through analytics, user research, surveys, or usability testing. You know how to turn conflicting inputs and large amounts of data into clear, actionable steps that lead to practical and elegant solutions.
Lay the foundations of the product team: set up rituals, frameworks, and hiring priorities that will guide our growth.
Who are we looking for:
You’ve built and shipped B2B SaaS products from zero to one (ideally 8+ years of experience).
You thrive in early-stage startups environments, where ambiguity, speed, and learning loops are the norm.
You’re equally comfortable talking to clients, aligning with founders, or rolling up your sleeves to write user stories.
Ability to move between strategic thinking (vision, positioning, roadmap) and hands-on execution (wireframes, user stories, acceptance criteria).
You have strong skills in product discovery, user research, and data-driven decision making.
You’ve designed and managed end-to-end user journeys and know how to balance user needs with business impact.
You speak the language of engineers — technical fluency with APIs, integrations, and data.
You’re a strong communicator who can engage stakeholders, inspire teams, and build trust with clients.
Curiosity, adaptability, and ambition to grow into a director-level product role in the short-to-medium term.
Above all, you’re curious, adaptable, and ambitious: someone who wants to become a cofounder-level leader and grow with the company.
Desirable:
Experience in Audit, Risk, Compliance, or ESG industries.
Network within the SaaS or risk management ecosystem.
Benefits:
A competitive salary.
A strong equity package (10%).
Becoming an entrepreneur with the support of the first Spanish Corporate Venture Builder and an industry-leading company, Erhardt.
Be part of Byld’s ecosystem: a team of teams that is either able to make pizza, prepare coffee, or build the next unicorn.
Actively participate in the disruption of the new era of Control Management.
Commitment and support of Erhardt and Byld’s liquid building team.
Experienced, motivated, and multidisciplinary team and board of directors.
The possibility to create a huge network within the startup and corporation ecosystems, being part of projects with big companies with a global impact.
A robust methodology and ability to launch new ventures that have given us the possibility to reduce risks in every venture we embark on.
