You'll bring deep technical expertise, lead by example, and help guide your team through tough engineering challenges, all while keeping performance, simplicity, and reliability at the heart of your work.

This is a hands‑on role where leadership comes from contribution. You'll help define direction, mentor others, and make sure the systems we build are robust, scalable, and easy to work with.

If you enjoy solving problems, and helping others grow, this could be a great fit.

Your responsibilities

• Lead by doing: Contribute to core systems while raising the bar on code quality, testing, and design.
• Drive technical conversations: Help your team navigate trade‑offs and make sound architectural decisions.
• Mentor and support: Share your experience with peers and junior engineers, and help others grow in their craft.
• Simplify the complex: Find elegant solutions to performance, reliability, and scalability challenges in our distributed rendering infrastructure.
• Unblock the team: Spot problems early, resolve bottlenecks, and keep projects moving forward.
• Champion quality: Promote practices like TDD, pair programming, and continuous delivery to keep us fast without sacrificing stability.

How We Work

• Build with ownership: You take responsibility for your work and see it through, from idea to production.
• Think beyond your team: You consider the broader system and collaborate across teams to build cohesive, maintainable solutions.
• Improve how we work: You help refine our engineering practices and tooling to make life better for every engineer on the team.
• Stay curious and humble: You're open to feedback, eager to learn, and always looking for ways to grow, and help others do the same.

A Typical Day Might Involve

• Pairing with another engineer to debug a tricky issue or spike a new feature
• Giving feedback on a design proposal or pull request
• Helping define technical priorities in a planning session with product
• Mentoring a newer teammate through a code review or whiteboard session
• Improving tests or tooling to keep deployments smooth and safe
• Jumping into logs or metrics to trace a performance regression in production

What You bring to the table

• Proven experience: 10+ years building and shipping production software, ideally in a SaaS or infrastructure context
• Strong fundamentals: Deep understanding of modern software engineering, performance tuning, and distributed systems
• Skilled in our stack: You're comfortable with TypeScript/Node.js and/or Golang, cloud-native tools (AWS is a plus). Experience with NestJS or Terraform is a bonus.
• Craft-focused: You write clean, maintainable code and advocate for simplicity in design
• Delivery mindset: You know how to balance speed with quality and when to optimize for each
• Mentorship skills: You enjoy helping others level up through thoughtful feedback and collaboration
• Communication: You explain technical topics clearly, both within the team and to stakeholders across the company
• Curiosity and initiative: You're not afraid to dig deep or take the lead on making things better

Bonus if you have experience in SEO, web performance, or rendering pipelines, but it's not a requirement.

What's in it for You

• Ultimate flexibility: We're 100% remote. You can work from wherever you like, whenever you like.
• Freedom and autonomy: We're a high‑trust team, and you'll be given lots of flexibility to solve problems in your own way — with plenty of help from the team when you need it.
• Minimum bureaucracy: We don't like to get bogged down with meetings and red tape. We like to be efficient and keep momentum steady & sustainable.
• Small & friendly team: We help each other out, have fun, and joke around.
• Our network: We are a community of entrepreneurial SaaS professionals that regularly exchange ideas, knowledge, learning and expertise with each other internally.
