Sr Full-Stack AI Engineer (Remote)

Description

About Superbench

Superbench is building the next generation of AI-powered sales and operations software for service businesses. We help companies that rely on inbound conversations - across WhatsApp, web chat, and other messaging channels - convert more leads, automate manual sales work, and operate more efficiently using conversational AI and real-time analytics.

Our platform combines an AI-native CRM, conversational sales agents, scheduling automation, and marketing analytics into a single system that directly impacts revenue for our customers. As we pivot and double down on AI-enabled product development, we’re rebuilding our engineering foundation to move faster, ship higher-quality software, and turn ambitious product ideas into production-ready systems.

About the Role

As a Senior Full-Stack AI Engineer, you will play a critical hands-on role in building and evolving Superbench’s AI-powered platform. Working closely with product and leadership, you will design, develop, and ship intelligent, customer-facing features that leverage modern AI capabilities.

This role is ideal for someone who is deeply experienced in applying AI in production environments, especially in building multi-step, multi-agent workflows, and who is equally comfortable working across the full stack. You will help turn ambiguous product ideas into reliable, scalable systems, with a strong focus on delivering real user value through AI.

You’ll contribute across backend, frontend, and AI systems - owning features end-to-end while collaborating with other engineers to maintain high standards in code quality, performance, and usability.

• Design and build AI-powered product features, including conversational interfaces, RAG pipelines, and multi-step / multi-agent workflows
• Own the implementation of backend and frontend systems across the Superbench platform
• Translate product requirements into scalable technical solutions, particularly for AI-driven use cases
• Work hands-on across the stack: Node.js/TypeScript and Python backend services, React frontend applications
• Integrate LLMs and AI tooling into production systems, ensuring reliability, performance, and strong user experience
• Build and maintain APIs, services, and data pipelines that support AI functionality
• Collaborate closely with product and design to iterate quickly on AI-driven features
• Contribute to engineering best practices around testing, code quality, and system reliability
• Participate in code reviews and support knowledge sharing across the team

Requirements

We are looking for a Lead Engineer who is excited to face challenges head-on, take ownership of the tech stack, and make key technical decisions to drive Superbench forward.

Note: While this role is remote, it is only open to candidates that are within ±3 hours of Singapore time zone (SGT), as this is where our offices are headquartered and all stakeholders are located.

• 4+ years of backend engineering experience, primarily using Node.js frameworks (e.g. Express, NestJS) and modern TypeScript
• 2+ years of frontend engineering experience building user-facing applications with React
• 2+ years of practical experience building and integrating AI systems into production applications
• Deep understanding of JavaScript and TypeScript
• Strong experience designing and building scalable backend systems, APIs, and services
• Solid experience with relational databases (e.g. PostgreSQL, MySQL), including schema design and query optimization
• Hands-on experience with NoSQL databases (e.g. MongoDB)
• Hands-on Python experience (2+ years), particularly for AI workflows, data processing, or backend services
• Strong experience building AI-powered customer-facing features, including:
• Retrieval-Augmented Generation (RAG) pipelines
• Multi-step and/or multi-agent AI workflows
• Prompt design, evaluation, and iteration
• Tool-using agents and orchestration frameworks
• Experience working with AI frameworks and tools such as OpenAI SDK, LangGraph, MCP, or similar
• Hands-on experience with vector databases (e.g. Pinecone or equivalents)
• Proven experience integrating complex AI flows into real user-facing products
• Strong problem-solving skills and ability to work in ambiguous environments
• Strong communication skills, with the ability to explain technical concepts clearly
• Strong spoken and written English

Nice to have:

• Experience working in early-stage startups or fast-paced product environments
• Familiarity with cloud platforms (e.g. GCP), CI/CD pipelines, and basic DevOps practices
• Experience with event-driven architectures, background jobs, or message queues
• Experience building real-time or conversational systems (e.g. chat, messaging, workflow automation)
• Exposure to analytics, data pipelines, or reporting systems
• Experience working with multi-tenant SaaS platforms
• Familiarity with security best practices, authentication/authorization, and data privacy considerations
• Experience collaborating in remote or distributed teams

About the interview process:

• Basic-fit and screening interview (20-30 minutes)
• A conversation with our CEO to get to know you better and understand your background.
• Review your experience and technical depth at a high level
• Discuss your interest in Superbench and early-stage roles
• Assess alignment with our team, culture, and expectations
• Take-home assessment (3-4 hours)
• A practical, real-world project designed to evaluate how you think and build across both backend and frontend, as well as integrating AI into customer-facing applications.
