Senior Backend Infrastructure Engineer

The future will look very different than today. 

According to the media, this future will be vibe coded. But this is not true.

Woz is the anti–vibe code platform. While others generate AI prototypes, Woz builds robust, scalable, secure, engineered products of the highest technical quality. This means anyone from a student launching their first idea to a Fortune 500 company reinventing its business can build, scale, and run world-class, customer-facing products on Woz.

Our ambition is bold: to become the standard on which all customer-facing products are built. Because in the end, the product in your customer’s hand matters more than anything.

Woz is a team of grizzled engineering vets that cut their teeth on deep learning, infra, and LLMs before they were cool. Collectively we’ve scaled products to millions of users, authored over 30 patents, and helped drive multiple exits.

Individually, we come from around the world; together, we’re united by a single mission: to make production-grade software accessible to anyone with an idea. We hold ourselves to the highest technical standards, move fast without cutting corners, and build like owners, because the future of software deserves nothing less.

What we believe:

• The future is bright. AI will unlock enormous prosperity by driving down costs and lowering barriers to building.
• The future will not be built by vibe coding. It will be built on a foundation of robust engineering, amplified by expertly applied AI.
• Quality matters more than ever. As the internet floods with AI-generated slop, products that are secure, scalable, and expertly crafted stand out amongst the rest.
• Long-Term > Short-Term. Woz exists to build a generational company with durable value, not to chase short-term, low-quality revenue.
• The highest-performing teams are flat, with every member taking deep ownership and accountability. We don’t get bogged down valuing processes over results.

About the role

• We are looking for an Infrastructure Software Engineer with 5+ years of experience to help design, build, and scale the systems that power our platform. This role is ideal for someone who thrives in fast-paced environments, enjoys building reliable infrastructure from the ground up, and takes full ownership of the software lifecycle from design and deployment to monitoring and optimization.
• You will focus on backend services, data models, APIs, and cloud infrastructure, ensuring our systems are secure, scalable, and observable. You’ll play a key role in shaping how code moves from development to production, improving deployment workflows, and building the tooling that keeps our platform fast and dependable.

Responsibilities

• Develop and Maintain Scalable Applications: Design, build, and maintain robust web applications using modern front-end and back-end technologies.
• Architect Scalable Solutions: Contribute to the system architecture and make high-level design decisions.
• Architect Modular Infrastructure: Write code in an extremely modular way to all for reuse and scalable maintenance across multiple implementations.
• Collaborate Cross-Functionally: Work closely with product managers, designers, and other engineers to define, develop, and launch new features.
• Optimize Performance: Ensure applications are efficient, secure, and performant at scale.
• Stay Ahead of Trends: Continuously research and implement the latest industry best practices, tools, and technologies.
• Mentor & Guide: Provide technical guidance and mentorship to junior engineers.

Requirements

• Education: Degree in Computer Science, Software Engineering, or a related field.
• Experience: 5+ years of hands-on experience in full-stack development.
• Backend & Cloud Engineering:
• • Deep expertise with Node.js, TypeScript, and API design (RESTful & serverless).
  • Strong experience architecting and deploying production systems on AWS (ECS, Lambda, CloudWatch, Route53, etc.).
  • Proficiency with Docker containerization and infrastructure-as-code tools such as AWS CDK or CloudFormation.
  • Strong understanding of Linux, shell scripting, and core networking concepts (DNS, VPC, load balancing, etc.).
• DevOps & CI/CD: Deep experience with Docker, GitHub, and CI/CD pipelines. Experience with deployment workflows, environment provisioning, and observability tooling.
• Database Knowledge: Experience with PostgreSQL, Supabase, and other databases.

Bonus Skills

• Experience with serverless or event-driven architectures.
• Familiarity with AI/ML infrastructure or integrating LLMs in backend systems.
• Background building SaaS platforms with multi-tenant or microservice architectures.
• Exposure to monitoring, alerting, and performance tuning of distributed systems.
