Job Level
About the role
- 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.
Requirements
- 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.
