Position Overview

We are seeking a highly sophisticated, attention-driven Sr. Frontend Engineer to join our growing product development team in a full-time remote contract capacity. In this senior client-side engineering seat, you will claim end-to-end technical ownership over features across our diverse frontend systems, bridging complex UI layouts with clean backend microservices. Moving far beyond boilerplate layouts, you will maintain dual-framework code stacks, configure frontend build pipelines, and proactively optimize digital experiences for performance, core web vitals, and universal accessibility rules. This position requires an independent engineering expert who treats agentic LLM developer tooling as an architectural catalyst to accelerate product deployment cycles without sacrificing syntax quality or unit validation coverage.

Key Responsibilities

• Dual-Framework Feature Engineering: Architect, code, and deploy highly performant frontend components across specialized product lines running on both React and Vue.js frameworks.
• End-to-End Application Ownership: Manage full application lifecycles end-to-end, steering user-facing features from raw UI designs through implementation, client-side testing, and continuous cloud deployment.
• Web Performance Optimization: Monitor and calibrate client-side script modules to optimize load latency, screen-paint speeds, browser memory tracking, and mobile responsive behaviors.
• API Integration Coordination: Collaborate directly alongside backend development squads to model clean, stateless, and efficient REST API payloads.
• Agentic LLM Tool Orchestration: Use next-generation developer tooling—including Claude Code, Cursor, Copilot, and Windsurf —critically reviewing generative output strings to accelerate feature delivery times securely.
• Precision Micro-Layout Audits: Maintain an elite standard of visual craft, identifying and fixing subtle element misalignments, missing skeleton loading structures, and asynchronous race-condition states.
• Build Toolchain Standardization: Fine-tune compilation rules, component routing layers, and application bundle configurations inside Next.js and Webpack frameworks.

Required Skills & Qualifications

• Demonstrated professional history operating as a Senior Frontend Engineer, Product Engineer, or Full-Stack Client Developer inside fast-moving software-as-a-service (SaaS) or product engineering companies.
• Profound, expert-tier programming fundamentals in core JavaScript (ES6+) , declarative web state management, and modern browser networking paradigms.
• Hands-on commercial history structuring production-grade applications using both React (with MobX or adjacent tools) and Vue.js (2.x / 3.x ecosystems) .
• Mastery across layout rendering files, including semantic HTML5 structures, advanced CSS preprocessors, flexbox layouts, and pixel-perfect design-system alignments.
• Verified engineering history leveraging agentic AI orchestration applications (such as Claude Code, Cursor, or Windsurf) within a professional production workflow.
• Outstanding verbal and written communication mechanics, with absolute professional fluency in English to manage asynchronous project tracking.
• Location Context: Full-time contract parameters open exclusively to qualified frontend engineers permanently residing in and authorized to operate from within Azerbaijan or Ukraine .
• Schedule Alignment: Absolute readiness to maintain standard online hours matching London operations (9:00 AM to 5:00 PM GMT / London time), Monday through Friday.

Preferred Strategic Indicators (Nice to Have)

• Prior experience deploying or maintaining high-traffic Next.js platforms inside production server-side rendered (SSR) configurations.
• Familiarity customizing frontend build tools, asset bundlers, or asset compiling graphs via Webpack .
• Practical familiarity building layouts with standardized modular visual toolkits, including Bootstrap or Material UI (MUI).

What We Offer

• Targeted Contract Compensation: A stable monthly budget scaling from $3,000 – $3,500 USD per month , distributed predictably via commercial contract routes.
• The exceptional creative opportunity to claim real system ownership and establish architectural standards across a prominent international PropTech web estate.
• Profound work-from-home remote parameters offering high professional lifestyle autonomy and an open-door developer workspace.
• A generous time-off architecture providing 20 days of paid annual vacation alongside additional rest days synced with the official UK public holiday calendar.
