وظيفة Senior Full Stack Engineer شاغرة لدى NovaLexi في الرياض

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.

• 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.

• 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.
