Job description

You’ll be one of the first people helping us build Clove from the ground up. Your work will directly shape how our customers interact with their advisors and manage their wealth for the first time in a human, guided, mobile-first way.

What you’ll do:

• Build the advisor-facing web platform from the ground up — including CRM-style views, milestone planning tools, and embedded AI assistance.

• Own the frontend and backend architecture of the Advisor Tools Pod using modern web technologies (e.g. React, Next.js, Node.js).

• Integrate key backend services and third-party platforms to surface client data, scheduling, compliance workflows, and portfolio context.

• Collaborate closely with product, design, and AI engineers to create intuitive tools that help advisors deliver world-class advice at scale.

• Ship fast while designing for compliance, observability, and long-term maintainability.

• Help shape advisor-facing workflows and internal patterns for full-stack development.

What we’re looking for:

• 5+ years of experience building modern full-stack web apps, ideally in fintech or in the productivity tooling space.

• Strong command of React/Next.js (or similar) on the frontend and experience with secure, maintainable backend services.

• Clear product thinking — you can turn complex requirements into elegant, intuitive tools.

• Experience integrating with third-party platforms (e.g. CRMs, identity providers, financial APIs).

• You're highly autonomous and comfortable working closely with design, product, and other engineers to shape and deliver end-to-end solutions.

• Bonus: exposure to event-driven systems, OpenAPI/GraphQL design, or AI-assisted product features.

Why join now:

1. Own the advisor experience from day one. Shape the core tools and workflows behind Clove’s advice engine.

2. Build from scratch alongside a small team of experienced engineers, designers, and product leaders.

3. Join a well-funded, high-trust environment where your work drives immediate and visible impact on how people manage their financial lives.

What we offer:

1. Competitive salary & meaningful equity — real ownership in what we’re building

2. London HQ with flexible working — we believe in time spent together, in person, but we also care about flexibility

3. A-grade tools & setup — top-tier hardware and your choice of software

4. Autonomy and impact — you’ll own your work end-to-end and help shape our direction from the early days

5. High-trust, high-performance culture — small senior team, no micromanagement, fast feedback loops

6. Mission with momentum — we're closing the advice gap for a new generation, backed by proven founders and real market insight

7. Regular offsites & in-person time — we make space for connection and collaboration

Our hiring process isn’t rigid, but our principles are clear:

• We’ll do what’s needed to build mutual trust: you’ll understand what we expect from you, and we’ll understand what you expect from us.

• We’ll aim for clarity of the role, though at this stage, some scope will evolve — and that’s part of the excitement.

• Expect conversations with the founding team and potential collaborators. No hoops for the sake of it — just real conversations, practical exercises if relevant, and space to ask questions.
