Job description

London, hybrid · Full-time, permanent or contract

About the Role

We are building a business intelligence product for lawyers: legal news and deal intelligence for business development, a tool for managing approaches to prospective clients and a live rankings system that lets lawyers credential their work against their peers. We launch later this year.

You will own the mobile experience in its build out during the next iteration after launch, working alongside the UX, Backend and QA streams. The data is heavy and our users are busy professionals, so the job is making a large amount of information legible in a few seconds. Greenfield build, no legacy mobile app, embedded with the delivery team day to day.

Responsibilities

• Build and ship the production application on iOS and Android, including the path through App Store and Play Store review.
• Present dense information on a small screen: lists, filters, search, sorting and detail views.
• Handle offline and cached states so the app stays useful on a train or in a client meeting.
• Consume and shape REST or GraphQL APIs in partnership with the backend engineers, rather than accepting whatever is handed over.
• Work with UX on what is feasible on mobile and with QA on coverage and device-specific issues.
• Maintain testing and CI/CD for mobile releases, then act on crash and performance data after launch.

Required Skills

• 4+ years building and shipping production either React Native or on iOS, with at least one app you launched on the App Store.
• Experience presenting dense data on a small screen.
• Testing and CI/CD for mobile releases.

Preferred Skills

• Early-stage product experience, where the stack and the patterns were still being decided.
• Data-heavy or analytics products, particularly designing for information density.
• Legal, financial services or another professional services domain.

Ideal Candidate Profile

• Has taken applications through review, release and the first weeks of live use.
• Opinionated about mobile. Will say so when a design fights the platform.
• Suited to early stage. Comfortable deciding on incomplete information and revisiting it later.

What We Offer

• A greenfield mobile build with real ownership, on a product going to market this year.
• A delivery team spanning UX, Data, AI, DevOps, Backend, Frontend, Infrastructure & Security and QA, so you are not the only engineer in the room.
• Hybrid working from London, permanent or contract.

Equal Opportunity Statement

We are committed to diversity and inclusivity. We welcome applications from every background and will make reasonable adjustments at any stage of the process on request.
