About The Position

Second Nature is looking for a Senior Software Engineer to help design, build, and scale high-quality software solutions that make a real difference for property managers and their residents. In this role, you will collaborate closely with cross-functional teams, contribute to architectural decisions, and help set the technical bar for the team around you. You'll own meaningful pieces of the product end-to-end, mentor less experienced engineers, and bring both craft and curiosity to everything you build. You'll be joining a newly formed team focused on building a next-generation experience for the customers. This is a high-impact opportunity to help shape a product area from the ground up - working closely with product and engineering leadership to define what best in class looks like. We're building in an era where AI is changing what's possible for engineering teams, and we want engineers who are running toward that. You should be actively using AI-assisted and agentic coding tools today - with a point of view on how they make you faster, sharper, and more effective. If you're genuinely excited about where AI is taking software development, you'll fit right in.

Requirements

5+ years of professional software development experience with a strong background in software design and architecture.
Experience with TypeScript, React and Next.js.
Experience with NestJS and PostgreSQL.
Solid understanding of cloud-native architectures with Kubernetes and Terraform.
Strong grasp of software architecture patterns - microservices, distributed systems, hexagonal architecture, domain-driven design, and similar.
Experience working in cross-functional agile teams and collaborating closely with product and design.
Strong communication skills - you can explain technical concepts clearly to both technical and non-technical stakeholders.
Active, hands-on use of AI coding tools (we use Claude Code) as part of your daily development workflow.
Experience with or strong curiosity about agentic coding workflows - using AI agents to automate development tasks, generate and review code, or accelerate system design.
Genuine enthusiasm for the future of AI in software engineering and a desire to be at the forefront of how it reshapes the craft.
