Staff Backend Engineer

Role Description

We’re looking for a Staff Backend Engineer to help define and scale the core systems powering our rapidly growing B2B SaaS platform. This is a deeply technical role focused on building reliable, high-performance infrastructure and backend services, while embracing AI-assisted engineering as a core part of how modern software gets built.

• Own major areas of backend architecture, including APIs, distributed systems, data models, infrastructure, and core business logic.
• Use AI-assisted engineering tools (e.g. Cursor, Claude Code, Copilot, ChatGPT, Devin, or similar) as part of your daily workflow to accelerate development, debugging, testing, documentation, and operational efficiency.
• Identify opportunities to integrate AI into both internal engineering systems and customer-facing platform capabilities.
• Design, build, test, deploy, and iterate on production systems end-to-end with a focus on reliability, scalability, and maintainability.
• Architect systems capable of supporting increasing scale, complexity, and evolving customer workflows.
• Define and implement modern testing, observability, and operational practices that improve system resilience and developer velocity.
• Build scalable abstractions, internal frameworks, and platform capabilities that enable faster product development across teams.
• Drive technical direction and contribute to long-term architectural decisions around performance, security, scalability, and platform evolution.
• Mentor engineers across the organization, sharing best practices and helping raise the technical bar for backend engineering and system design.

Qualifications

• 8+ years of backend or full-stack engineering experience, ideally in SaaS or high-scale distributed systems environments.
• Proven experience designing, scaling, and operating complex backend systems from early-stage growth through maturity.
• Deep expertise in distributed systems, APIs, data modeling, infrastructure, and backend architecture patterns.
• Strong proficiency with modern AI engineering workflows and tooling. You actively use AI to improve development speed, problem solving, system understanding, and operational efficiency.
• Strong execution mindset with the ability to balance rapid iteration against long-term reliability and maintainability.
• Experience building secure, observable, fault-tolerant systems in production environments.
• Collaborative and pragmatic approach. You work effectively across engineering, product, infrastructure, and data teams.
• Adaptability and engineering judgment matter more to us than specific frameworks or languages.

• Competitive Compensation: Competitive salary and equity packages for all employees
• Healthcare Plan: Platinum medical, dental, and vision
• Free life insurance: Including long-term disability & short-term disability
• Unlimited PTO: Uncapped vacation days & paid holidays
