Software Engineer

THE COMPANY

WellStat is a leading PropTechcompany providing integrated solutions for building management, indoor air quality monitoring, and energy optimization. The business operates across North America and the UK with a focus on sustainable building technologies and expanding their smart building platform globally.

THE ROLE

This is a hands‑on individual contributor role where you’ll write production code daily, collaborate closely with your teammates, and take ownership of features from design through deployment. You’ll work in a modern TypeScript, Node.js, React, and AWS stack. You’ll play a key role in shaping the product as the company grows.

What You’ll Do

Engineering

• Build and ship production features in TypeScript, Node.js, and React.
• Design, implement, and deploy backend services and APIs on AWS using Node.js and TypeScript.
• Build responsive, well‑structured React front‑end components and interfaces.
• Write unit and integration tests, participate in code reviews, and uphold coding standards.

Technical Responsibilities

• Architect and maintain AWS infrastructure including ECS, S3, RDS, and related services.
• Collaborate with product managers and engineers to define and deliver features.
• Debug, profile, and optimize application performance across the full stack.
• Contribute to CI/CD pipelines and deployment automation on AWS.
• Participate actively in sprint planning, grooming, and retrospectives.

Collaboration & Delivery

• Take ownership of tasks end‑to‑end: from scoping and design through implementation, testing, and deployment.
• Communicate progress, surface blockers early, and collaborate with teammates to keep delivery on track.
• Ask questions, share context, and contribute ideas during planning and grooming sessions.

AI‑Assisted Development

• Use AI tools (e.g., Cursor, Claude) to accelerate development responsibly.
• Apply AI‑assisted development professionally - speeding up work while maintaining review, judgment, and quality.
• Help define guardrails and workflows for AI‑assisted coding.

Technical Environment

• Primary stack: Node.js, TypeScript, React
• Additional technologies: Python (data processing), some legacy Java
• Cloud: AWS (ECS, S3, RDS, Terraform, CloudWatch)

The ideal candidate

Required

• 5+ years of professional software development experience.
• Strong hands‑on experience with TypeScript, Node.js, and React.
• Solid AWS experience - comfortable deploying and operating cloud infrastructure, not just using hosted services.
• Experience writing tests (unit, integration) and a genuine care for code quality and maintainability.
• Comfort working in a fast‑moving environment with ambiguity and evolving requirements.
• Familiarity with Scrum or Agile workflows.
• Positive, collaborative attitude - someone who makes the team better to work with.
• Interest in AI‑assisted development and the judgment to use it responsibly.

Nice to Have

• Experience with Python or Java.
• Familiarity with infrastructure‑as‑code tools (e.g., Terraform, AWS CDK, CloudFormation).
• Experience with relational databases (PostgreSQL, MySQL) and data modeling.
• Background in establishing coding patterns or modernizing codebases.
