The Opportunity

Terra35 is looking for a Co-Founder and Chief Scientific Officer to join the founding team as a full peer and to own the science of the company from the ground up. This is a founding role.

• You will identify the scientific, technical and innovation opportunities that strengthen long-term platform value, and you will assess each one for feasibility, development pathway, technical risk and strategic fit.
• Scientific Partnerships and Team Leadership
• You will own the scientific oversight of external development partners, research organizations and collaborators, and you will ensure that their work stays aligned with company priorities and milestones.
• You will cultivate, chair and lead the company's scientific advisory board, and you will recruit the senior advisors who provide external validation and access to specialized research capability.
• You will build and lead the Terra35 scientific organization over time, recruiting the scientific talent and collaborators that the platform requires.
• You will establish a culture of scientific rigor, curiosity and excellence.
• Scientific Representation
• You will serve as the senior scientific voice of the company with investors, customers, regulators, strategic partners and the wider scientific community.
• You will participate actively in investor engagements, including pitch meetings, scientific diligence sessions and roadshow activity during fundraising.
• You will contribute scientific perspective to external communications and to how Terra35 positions itself across investor, customer and market-facing audiences.

• You will support patent strategy, freedom-to-operate assessments and invention development.
• You will provide the scientific leadership that underpins regulatory pathways and product substantiation.
• You will ensure that scientific evidence and data packages meet the applicable regulatory requirements.

Founding Responsibilities

• You will act as a Co-Founder of Terra35, contributing to overall company strategy, governance, financing, culture and long-term direction alongside the founding team.
• You will support fundraising and diligence as a principal member of the founding team rather than as a supporting technical voice.
• You will help define the standards, operating culture and long-term ambition of the company from its earliest stage.
• You will bring scientific conviction, commercial judgment and founder-level accountability to the next phase of the company.

Who We Are Looking For

Required

• You hold a PhD in plant biology, plant biotechnology, plant cell culture, synthetic biology, metabolic engineering, bioprocess development or a closely related discipline.
• You have significant experience leading scientific programs within biotechnology, food technology, agricultural technology, specialty ingredients or a related industry.
• You have translated scientific innovation into commercially relevant outcomes.
• You have managed complex external research or development partnerships.
• You communicate clearly and can engage scientific, commercial and investor audiences with equal confidence.

Preferred

• You bring direct experience in plant cell culture or plant-based production systems.
• You have worked with fermentation, cell cultivation, scale-up or process development.
• You have held executive leadership roles in an early-stage or growth-stage company.
• You have supported fundraising and investor diligence.
• You have cultivated and chaired a scientific advisory board.

Founder Mindset

• You want to build a company rather than simply join one, and you are motivated by ownership and mission ahead of title.
• You are comfortable with the ambiguity, pace and personal risk that define an early-stage venture.
• You are ready to commit at a founding level and to stand behind the science as its accountable owner.

What Success Looks Like

Within your first 12 to 18 months, you will have established a compelling scientific vision and roadmap as a member of the Founding team, identified the key scientific risks and set a disciplined plan to mitigate them, increased investor and stakeholder confidence in the scientific direction of the company, and strengthened the oversight of external scientific partners. You will have advanced the platform toward its key technical milestones, built a strong Scientific Advisory Board with a functioning rhythm that contributes meaningfully to the roadmap and to risk mitigation, and laid the foundation for a high-performing scientific organization.

Founding Terms

Equity: This is a founding role and it carries meaningful founding equity, set through direct conversation and commensurate with your founding contribution. Founding equity vests on standard founder terms, typically a four-year schedule with a one-year cliff, and the detail is set out in our founders' agreement.

Compensation: Compensation is initially equity-based and is expected to transition to salary following financing and as company budget allows, with the overall package commensurate with experience and founding contribution.

Standing: You join as a Co-Founder with genuine ownership, real influence and an equal seat at the founding table.

Location: Flexible. Terra35 is Irish‑incorporated and works with partners across Europe. The role will require availability for investor, partner and team engagement across the relevant time zones.
