Associate Director of Finance

Peptone is building a Product Engine to generate small-molecule drug candidates against intrinsically disordered proteins. Our Product Engine reads the physics of disordered proteins and models it with AI, combining measured ensemble biology with experimental physics, computation and translational work. We use those insights to design small-molecule drug candidates for hard-to-treat cancers, with a shared evidence loop which can span multiple therapeutic areas, including oncology, immunology and inflammation, and CNS.

Our interdisciplinary team spans academic science and pharmaceutical research, connecting measured protein dynamics with experimentally grounded models, candidate design and biological validation. We are growing across Switzerland, the UK and the US as our programs move toward IND-enabling work and the clinic.

Peptone is backed by F-Prime Capital, Bessemer Venture Partners, Hoxton Ventures, Walden Catalyst, the Banga Family Trust and Taplow Blue Capital.

Delivering first-in-class medicines for better patient outcomes is our obsession. Translating biophysics of intrinsic protein disorder to generate de novo therapeutics is our passion.

We are hiring our first US finance leader to own our US accounting and compliance, and to produce our monthly group consolidation and month-end pack. Your initial priorities will be to establish a reliable US close, deliver the group consolidation on schedule, and build a consistent approach to R&D accruals and budget-versus-actual reporting.

You will be hands-on in the US close and own the total consolidation, with support from the outsourced US accounting firm on selected activities. You will also work with our US tax advisers and auditors, and bring R&D and clinical trial accruals in-house as our programs move toward the clinic.

Alongside the core role, you will help our Executive Director of Finance with budget-versus-actual reporting, discussing variances with budget owners and supporting routine forecast updates. There are plenty of opportunities to get involved in other projects as Peptone grows, including (but not limited to) system implementations, AI use within the finance function, and Swiss and UK audits and accounting.

• Own the relationship with our outsourced US accounting firm: setting scope and deadlines, reviewing their work, and holding them to quality and timeliness
• Own the quality of the US books and month-end, with the firm processing and you reviewing and approving
• Assess whether the firm remains the right fit as we grow, and lead a change of provider if needed

• Work with our US tax advisers on all required federal and state filings, maintaining a US tax compliance calendar
• Coordinate with tax advisers to identify, document and support applicable R&D tax credit claims

• Prepare for and manage audits as and when they are required, and keep the US books audit-ready with clear schedules, policies and controls

• Produce the monthly group consolidation across our US, UK, Swiss and Italian entities under US GAAP, including intercompany eliminations and currency translation
• Deliver a month-end pack for review by our Executive Director of Finance, to an agreed timetable
• Bring R&D and clinical trial accruals in-house: milestone- and enrollment-based accruals, CRO and investigator invoice recognition, and pass-through cost tracking, working directly with program leads
• Own project-level accounting so program costs are tracked accurately and consistently

• Act as the local finance contact for US budget holders, running budget-versus-actual conversations and challenging spend that doesn't hold up
• Help with the global budget and forecast: US inputs, analysis and variance commentary
• Take on ad hoc projects to streamline FP&A and reporting, using AI and advanced Excel to cut manual work and error risk, and contribute to systems decisions

• A recognized accounting qualification (CPA preferred)
• 8+ years of finance and accounting experience, including significant time in a biotech company – ideally pre-revenue, IND-enabling or clinical-stage
• Strong US GAAP knowledge, including ASC 730 (research and development costs) and ASC 842 (leases)
• Hands-on consolidation experience – you have personally built group consolidations and month-end packs, including intercompany eliminations and currency translation
• Experience of booking R&D accruals
• A track record of managing outsourced accounting firms and external advisers, including changing provider where needed
• Experience working with US tax advisers on federal and state compliance
• Proven ability to work autonomously as the senior finance person in a location, with the wider finance team in a different time zone, in a fully remote role
• Willingness to travel occasionally to San Francisco and Switzerland

• Clinical trial accounting: milestone- and enrollment-based accrual methodology, CRO and site invoice review, and pass-through cost tracking
• Experience in a global business, working across multiple countries, currencies and statutory regimes, and within a US parent or holding company structure
• Experience identifying and claiming US R&D tax credits
• FP&A experience, including supporting budget cycles and partnering with non-finance budget holders
• Experience of working outside the US, or embedded with non-US teams

• A non-hierarchical environment where everyone has a voice to influence and shape the company's future direction
• A highly dynamic environment with plenty of opportunities for career development
• A highly skilled and interdisciplinary team that is passionate about proteins, science and business
• A unique company giving you the opportunity to push the boundaries of biopharmaceutical drug development
• A flexible working setup to ensure a work-life balance

Rigorous science, done with kindness, for the patients waiting on it. We do our work in the open, with each other and for the people waiting on the other end of it.
