Staff Engineer 

About Mixmax

Mixmax is the #1 product helping revenue teams work proactively by eliminating busywork and creating seamless customer experiences. As we scale, we’re looking for staff-level engineers who thrive in startup environments - people who are energized by building, iterating, and driving impact with autonomy.

This is more than a coding role. It’s an opportunity to shape the technical direction of a fast-moving, product-led company with thousands of users. As a Staff Engineer at Mixmax, you’ll work across teams to influence key product decisions, ship high-impact features, scale our architecture, and level up our engineering culture.

We move fast, operate globally, and prioritize clear thinking, kind communication, and pragmatic solutions.

What You’ll Do (Role & Impact)

You’ll operate in a dual mandate: part of your time will be spent deeply embedded in a product team, driving design, delivery, and technical excellence; the rest will be spent working at the company level, partnering with the other Staff Engineer to shape Mixmax’s technical strategy and culture.

Together, you’ll form the most senior technical voice in the company, reporting directly to the Director of Engineering.

• Be the senior technical voice in your team: design, review, mentor, and help deliver major features at high quality.
  
  
• Partner with the other Staff Engineers to drive cross-company technical strategy, architectural standards, and engineering culture.
  
  
• Own cross-cutting initiatives: scalability, reliability, developer experience, system evolution.
  
  
• Define, evangelize, and maintain lightweight guardrails (RFCs, ADRs, patterns etc) that scale with our team.
  
  
• Work alongside PMs, Designers, and Engineering leadership to align on direction, push back when needed, and ensure architecture enables (not constrains) product goals.
  
  
• Raise the bar on quality, mentoring engineers, and contributing to how we work, review, and make decisions.
  
  
• Own your impact. At this level, you’ll define what success looks like: spotting high-leverage opportunities, setting your own direction, and making tangible improvements that strengthen how we build, ship, and collaborate.
