This role is about driving architectural leadership that directly translates to business success. You will be central to scaling a platform that is redefining lending in the SME space.

Requirements for the Principal Engineer:

• 🏗️ Proven architectural leadership and deep technical expertise in backend technologies (preferably Python/Django or React/Typescript) at scale.
• 🤝Strong track record of collaboration with non-engineering stakeholders (Product, Commercial) to deliver measurable business outcomes.
• 💡Experience in FinTech, E-commerce, or Product-Led SaaS businesses where engineering directly impacts commercial metrics (e.g., conversion rate).
• 📈Recent roles must demonstrate a blend of hands‑on delivery with strategic system design, avoiding roles focused purely on internal platform or infrastructure.
