Senior/Staff Software Engineer

About the Role

Second Nature is looking for a highly experienced Senior/Staff Software Engineer to lead the development of innovative and scalable software solutions. In this role, you will work closely with cross-functional teams to design, implement, and maintain mission-critical systems. You will also mentor junior engineers and contribute to the company’s overall technology strategy.

Key Responsibilities

• Lead the design, architecture, and development of high-performance, scalable software systems

• Write, test, and maintain high-quality code, ensuring it meets both functional and non-functional requirements.

• Contribute to architectural decisions, ensuring scalability, performance, and maintainability of software systems.

• Uphold coding standards, best practices, and guidelines while conducting code reviews to ensure high-quality software.

• Analyze and resolve complex technical issues, optimizing code and improving system performance.

• Work closely with product managers, designers, and other engineers to understand business requirements and translate them into technical solutions.

• Drive continuous improvements in code quality, development processes, and team efficiency.

• Create and maintain technical documentation, including architecture diagrams and API specifications. Communicate technical decisions and strategies clearly to both technical and non-technical stakeholders.

• Participate in agile development processes, including sprint planning, stand-up meetings, and retrospectives.

• Stay up-to-date with emerging technologies and industry trends to drive innovation.

Key Outcomes

• Backend services and APIs that ship on schedule and hold up in production, with defects caught in review or test rather than by customers.

• Clean, well-tested code that other engineers can pick up and extend without a translation layer, raising the bar for maintainability across the codebase.

• A continuous delivery pipeline and monitoring setup that stays healthy, supporting trunk-based development so the team deploys with confidence instead of caution.

• Product ideas translated into working technical solutions, with design and product partners who see you as a reliable thought partner early in the process rather than a downstream implementer.

Preferred Qualifications

• 5+ years of professional software development experience, with a strong background in software design and architecture.

• Experience with TypeScript and Node.js.

• Experience with AWS, PostgreSQL, and SQL.

• Experience using AI coding tools (like Claude Code, Copilot, Cursor, etc.) in your daily workflow, with genuine excitement about where agentic AI is headed for software development.

• Deep knowledge of software architecture patterns and design (e.g., microservices, distributed systems, hexagonal architecture, domain-driven design, etc).

• Strong problem-solving and analytical skills.
