Staff EngineerAbout 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.
You’re a pragmatic, systems-minded engineer who enjoys leading through influence as much as through code. You think in terms of long-term impact, operate comfortably in ambiguity, and find energy in improving both technology and culture.
Your Experience Likely Includes- You’ve built and shipped complex products in startups or fast-paced environments where autonomy and impact matter.
- Deep expertise in backend development with the versatility to work across the stack.
- Strong hands-on experience with TypeScript, Node.js, and familiarity with MongoDB and AWS-based architectures (bonus for EventBridge, Lambdas, DynamoDB, IaC).
- Exposure to or curiosity about AI tools and their real-world application in user-facing products.
- Experience working in cross-functional product teams, balancing product and technical decisions.
- A track record of pragmatic, high-impact technical calls and influencing outcomes across teams.
- Experience mentoring and levelling up other engineers.
- Excellent communication skills - you can simplify complex systems and align people around ideas.
- Dual Leverage: Work hands-on in a product team while shaping company-wide technical direction.
- Most Senior Technical Voice: You and the other Staff Engineer are the technical backbone of Mixmax, representing engineering at the highest level.
- Direct Access & Influence: Report to the SLT (Director of Engineer) - your proposals go straight to leadership.
- Cultural Leadership: Help shape engineering practices and culture across
- Ambiguity & Autonomy: Lead through fuzzy problem spaces and shifting trade-offs with freedom to decide how.
High Impact: Your work will unblock multiple teams, accelerate delivery, and shape the long-term system architecture.
💜 Why Mixmax?- We’re a product-led company with strong product–market fit, ambitious new AI initiatives, and a clear mission
- You’ll join at a pivotal moment - shaping the next generation of our platform and helping define how Mixmax scales technically and culturally.
- You’ll work in a team that values ownership, creativity, and building things that matter, where good ideas can come from anywhere.
- You’ll have autonomy, trust, and direct access to leadership, with the support to explore high-leverage opportunities and make real impact.
