Senior Full Stack Engineer

Design and build across the whole platform: Rails and GraphQL on the server, Next.js and React on the client, and the AI features that run through both. Secure, multi-tenant, bilingual, and engineered to the standard a regulated enterprise or government client expects.
What you'll do
Design and build backend services and the platform's GraphQL API on Rails 8 and PostgreSQL.
Build the product surface in Next.js 16 and React 19: server components by default, Apollo Client for data, and typed GraphQL generated from the schema.
Model complex IP-lifecycle domains: patents, trademarks, renewals, deadline calculation and multi-jurisdiction rules.
Implement row-level multi-tenant data isolation and role-based access control (RBAC), end to end from the resolver through to the rendered page.
Build the AI-backed features on both sides of the wire: agentic services, document analysis, and streaming chat and summaries over ActionCable, with the evaluation and guardrails that keep output quality honest.
Own integrations with external systems: patent-office and registry APIs, SSO (SAML and OIDC), billing, and document pipelines.
Ship the interface bilingually: every screen works in English and Arabic including right-to-left, using logical CSS and the shared design system.
Own performance, reliability and security (SSO/MFA, encryption, secure SDLC) aligned with NCA controls and PDPL.
Ship fast with AI-assisted development such as Claude Code, and build the guardrails (review gates, automated tests, security checks) that keep that speed safe.
Set engineering standards, review code, and mentor other engineers.
And all responsibilities given by the direct manager.
What we look for
8+ years building production software, including delivery for large-scale organisations: enterprise or government platforms, high data volumes, and a significant integration surface.
Genuinely full-stack: you have owned features from the database through the API to the rendered interface. Strong on at least one side, and not a passenger on the other.
Depth on the server: a modern backend framework (Ruby on Rails strongly preferred), expert relational database design in PostgreSQL, and background job processing (Solid Queue, Sidekiq or equivalent).
Production React and TypeScript, ideally Next.js App Router with server components.
Proven GraphQL on both sides: designing schema, resolvers and performance (graphql-ruby preferred), and consuming it on the client against a typed, generated schema (Apollo Client).
Delivered enterprise-grade, multi-tenant SaaS, and comfortable with what a large multi-stakeholder programme demands: availability and performance targets, regulatory requirements, and a client who expects to be kept informed.
You write tests as a matter of course, across unit, request and end-to-end, and you treat a failing build as a stop-work condition.
Fluent with AI coding tools such as Claude Code, and thoughtful about where they need guardrails so speed never costs correctness or security.
Experience in, or genuine comfort working in, a fast-paced startup environment: self-managed time, adapting to changing priorities, following tasks through, and delivering on short timelines when needed.
Preferred — Experience building LLM-backed product features where output quality matters, including evaluation and guardrails.
Preferred — Experience building bilingual or right-to-left interfaces.
Preferred — Experience working in government or regulated environments.
Preferred — Domain exposure to IP or legal technology.
Preferred — Familiarity with Google Cloud and containerised deploys.
Preferred — Bilingual, Arabic and English.
