Job description

We’re looking for a highly engaged, self-directed developer who can turn product ideas, PRDs, and UX mockups into exceptional working software.

This is a hands‑on role for someone who thrives in a fast-moving, AI-native development environment. You’ll build full-stack web products with substantial LLM functionality—from compelling product demos to polished, production-ready experiences.

Our workflow is PRD-driven and highly iterative. We work primarily in Cursor and Codex, using modern AI-assisted development practices to move quickly without sacrificing product quality. Experience with OpenClaw, agentic orchestrators, or multi-agent systems is a major advantage.

Responsibilities:

• Turn PRDs, UX mockups, and loosely defined ideas into cohesive working products.
• Build responsive, polished full-stack web applications.
• Design and implement meaningful LLM-powered features—not superficial AI add-ons.
• Develop agentic workflows, tool integrations, structured outputs, and orchestration logic.
• Create high-impact prototypes and product demos at “vibe-coding speed.”
• Make thoughtful product, UX, and technical decisions without requiring constant direction.
• Collaborate closely with founders, designers, and product stakeholders.
• Identify missing requirements, edge cases, and opportunities before they become blockers.
• Use AI development tools effectively while maintaining strong engineering judgment.
• Own features from initial concept through implementation, deployment, and iteration.

Qualifications:

• Proven ability to independently ship complete products or substantial features.
• Experience building production applications with LLMs and related APIs.
• Strong product instincts and attention to UX details.
• Ability to translate mockups into responsive, polished interfaces.
• Comfort working from PRDs while resolving ambiguity proactively.
• Experience with modern frontend frameworks such as React, Next.js, or equivalent.
• Strong backend and API development skills.
• Familiarity with databases, authentication, cloud deployment, testing, and observability.
• Ability to balance development speed with reliability and maintainability.
• Clear communication, sound judgment, and a high level of personal ownership.

Nice to have Qualifications:

• OpenClaw experience.
• Agentic orchestrator or multi-agent system experience.
• Experience with tool calling, MCP, RAG, memory systems, evals, and structured generation.
• Experience building human-in-the-loop AI workflows.
• Deep familiarity with Cursor, Codex, or similar AI-native development environments.
• Experience converting rapid prototypes into scalable production systems.
• A portfolio of polished AI products, experiments, or interactive demos.
• A comprehensive benefits package (Health, Dental, Life Insurance and RRSP).
• Remote work from home (available options).
• The opportunity for career growth and development.
• A collaborative and inclusive work environment.
