About the Role

As a Senior Frontend Engineer at Mobi, you will join a highly creative, fast-paced and fearless team tasked with building the next generation of AI-driven solutions.

We’re seeking a passionate and innovative Frontend Engineer to help define the next generation of intelligent customer experiences at the intersection of travel and AI. In this role, you’ll build elegant, highly interactive user interfaces that power AI-driven search and recommendation systems, virtual concierge services, and data-rich dashboards for analytics and visualization. You’ll collaborate closely with clients and cross-functional teams to translate user needs into beautiful, intuitive digital experiences — from concept through delivery.

You’ll be working on cutting-edge products that integrate with state-of-the-art AI platforms, including interactive AI assistants and app integrations based on the Model Context Protocol (MCP). This includes helping define how users interact with models and immersive AI interfaces beyond plain text — building experiences that connect ChatGPT, Claude, and other AI platforms to brand ecosystems with rich, responsive visual UIs rather than just conventional text responses. MCP Apps, a new extension of the MCP standard, enables real-time interactive components within AI chat environments, and you’ll help leverage this technology to create seamless, useful tools for our customers.

We work with major global brands and industry leaders to shape the search and concierge experience for their users. Some client engagements involve deep collaboration to understand unique requirements and deliver tailored solutions, while others push the boundaries of what’s possible with evolving AI ecosystems. If you thrive at the intersection of bleeding-edge technologies, customer engagement, and beautifully designed front-end systems, this is your opportunity to make a major impact.

Key Responsibilities:

• Develop, test, and maintain scalable front-end applications using modern frameworks and libraries (e.g., React).
• Translate UI/UX design wireframes and prototypes into high-quality, responsive, and accessible code.
• Collaborate with cross-functional teams to define, design, and ship new features.
• Optimize applications for maximum speed, scalability, and performance.
• Stay current with front-end trends, tools, and emerging AI technologies.
• Review code to troubleshoot, debug, and resolve issues.
• Own the full frontend lifecycle from development through testing and shipping, while implementing best practices for code quality, maintainability, and comprehensive testing (unit, integration, and end-to-end).

Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or related field—or equivalent practical experience.
• Proficiency in HTML5, CSS3, JavaScript (ES6+).
• Experience with React framework.
• Experience with TypeScript.
• Familiarity with testing frameworks (e.g., Playwright, Jest, Cypress).
• Experience and comfort using AI Tools (CodeX, Claude Code, Copilot, etc.) to automate workflows
• Understanding of backend APIs, and RESTful services.
• Understanding of responsive design principles and cross-browser compatibility.
• Experience with build tools and version control (e.g., Next, Vite, Git).
• Strong problem-solving skills and a collaborative mindset.
• Recent Experience working on AI Applications.
• Bonus: Understanding of MCP and response streaming.

About the Role:

As a Cloud Security & Compliance Engineer at Mobi, you’ll partner with a dynamic, forward-thinking team to build the resilient foundations that power our cutting-edge web experiences and AI-driven solutions. You’ll play a key role as the Security Engineering SME and Systems Builder, shaping the technologies that protect our travel-planning and logistics systems, which are used by some of the world’s leading brands.

This role blends technical engineering with the meticulous follow-through needed for compliance and documentation. You’ll be a representative for our customers and a creative partner for our engineers, focusing on audit-readiness as much as secure code. It’s an engaging, high-impact role where you move the business forward by finding "the secure way" to help our team ship and scale.

Key Responsibilities:

• Develop, test, and maintain scalable security guardrails to ensure a consistent, secure-by-default posture across our AWS and GCP environments.
• Navigate the human side of security by acting as a collaborative partner to our engineering teams; you will identify missing standards, negotiate solutions, and proactively suggest "the secure way" to build features rather than acting as a gatekeeper.
• Partner with our customers' security teams to align our architecture with their specific security patterns and represent Mobi’s robust security posture during technical deep-dives and reviews.
• Translate high-level security patterns and compliance frameworks (SOC 2 and GDPR) into high-quality, hardened infrastructure code and automated evidence collection.
• Review system designs to troubleshoot vulnerabilities, debug misconfigurations, and resolve architectural security gaps before they reach production.
• Own the security lifecycle—from initial threat modeling and customer alignment through to automated testing, shipping, and audit-ready reporting.
• Implement best practices for code quality, secret management, and maintainable security patterns across the entire engineering organization.
• Stay current with cloud-native security trends, multi-cloud vulnerabilities, and emerging AI-driven security technologies to proactively protect our AI-powered solutions.

Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or a related field—or equivalent practical experience in technical security.
• Strong hands-on experience securing AWS and GCP infrastructure (e.g., API Gateway, Identity, Networking, Encryption, and Logging).
• Deep understanding of technical controls for SOC 2 and GDPR.
• Deep understanding of backend APIs, and RESTful services from a Zero Trust and data protection perspective.
• Proven ability to design and implement security frameworks in ambiguous or rapidly evolving environments, building scalable processes and guardrails where none previously existed.
• Strong problem-solving skills and the ability to work cross-functionally to align security goals with developer velocity.
• Comfortable reading and navigating modern codebases (e.g., TypeScript/JavaScript or Python) to conduct security reviews and understand application logic.
• Recent experience working on AI Applications, with an understanding of privacy concerns and security risks specific to LLMs.
• Excellent interpersonal and communication skills; able to lead high-stakes technical deep-dives with enterprise partners and negotiate security standards across teams using a collaborative, "solution-first" approach.  

Bonus:

• Experience using Infrastructure as Code to build and manage secure environments (e.g., Terraform or CloudFormation/CDK).
• Experience using AI Tools (Claude Code, GitHub Copilot, etc.) to automate security policy generation and workflow audits.
