Staff Software Engineer



Software Engineering
San Francisco, CA, USA
Posted on Thursday, November 9, 2023
At MainStreet, we’re problem solvers.
Our products aim to do one thing: save startup founders and small business owners time, money, and peace of mind. We started by demystifying complicated tax credits, saving over $100M – and countless hours of tax code research 🥱– for founders in nearly every industry. Since our sort-of viral beginnings in 2019, we’ve raised a $60M Series A, expanded our product lines (with more in the works), and grew from 3 employees to our current team!
We owe our success to the strength of our team. Before joining MainStreet, we helped build companies like Intuit, PayPal, Google, Apple, Coinbase, Gusto, LinkedIn, Slack, and more. We’re fellow founders, engineers, accountants, designers, dog (and cat) lovers, adventurers, coders, and parents. We move fast. We think big. We don’t take ourselves too seriously. And we’d love for you to join us.
The opportunity
We are seeking a highly skilled and experienced Staff Software Engineer to join our dynamic and fast-paced team. The ideal candidate will have a deep understanding of modern software development, microservices architecture, and cloud infrastructure. This role is key to our continued success, as it involves not only building product features but also providing architectural guidance and performing DevOps tasks to ensure the reliability and scalability of our systems.

What you’ll do

  • Software Development: Develop, enhance, and maintain high-quality software products and features using Node.js and TypeScript. Collaborate with cross-functional teams to ensure that the codebase is clean, scalable, and maintainable
  • Architectural Guidance: Provide technical leadership and guidance in the design and implementation of microservices architecture. Ensure that our systems are built to be efficient, scalable, and reliable
  • Kubernetes and Terraform: Utilize your expertise in Kubernetes and Terraform to design, deploy, and manage containerized applications and infrastructure. Implement best practices for container orchestration and infrastructure as code
  • DevOps Tasks: Collaborate with the DevOps/SRE team to automate and streamline deployment processes, monitoring, and system maintenance. Ensure high availability and reliability of our services
  • Collaboration: Work closely with product managers, software engineers, and other stakeholders to understand business requirements and translate them into technical solutions. Foster a collaborative and inclusive work environment
  • Code Reviews and Mentoring: Review code from team members and provide constructive feedback. Mentor junior engineers, helping them grow and improve their skills

What we’re looking for

  • Bachelor's or Master's degree in Computer Science or related field
  • 8+ years of experience in software development
  • Expertise in Node.js, Javascript/TypeScript
  • Proven expertise in Kubernetes and Terraform, with a strong understanding of containerization and cloud-native technologies
  • Prior experience in a role that involved providing architectural guidance and performing DevOps tasks
  • In-depth knowledge of microservices architecture and best practices
  • Strong problem-solving and analytical skills with a keen attention to detail
  • Excellent communication and collaboration skills


  • Base salary range for this position is $195,000 - $215,000 and is based upon years of experience that is commensurate with the level of the position
  • Robust equity program with significant upside potential
  • Benefits including medical, dental, vision, disability, life, and 401k
