We're looking for a Senior Full Stack Engineer with a strong backend focus who thrives in fast-paced environments and enjoys taking ownership of complex technical systems from architecture through production. This role is ideal for someone who combines deep backend expertise with product-minded engineering and enjoys solving challenging infrastructure and scalability problems.
You'll work closely with founders, engineering leaders, and product teams to build the systems that power next-generation AI products, helping shape both the technical foundation and future direction of the platform.
What You'll Do- Design, build, and maintain scalable backend systems and APIs powering core product functionality.
- Develop and ship full-stack features from backend services through to customer-facing interfaces.
- Build reliable infrastructure that supports high-performance, real-time applications.
- Collaborate closely with engineering, product, and leadership teams to define and deliver new capabilities.
- Design systems that scale efficiently as product usage and complexity grow.
- Improve platform reliability, observability, monitoring, and operational tooling.
- Contribute to architectural decisions and long-term technical strategy.
- Optimize performance, security, and developer experience across the platform.
- Help establish engineering best practices and contribute to a strong culture of technical excellence.
What We're Looking For- 5+ years of professional software engineering experience.
- Strong backend engineering experience building and operating production systems.
- Advanced proficiency with TypeScript and modern backend development practices.
- Experience building scalable APIs, distributed systems, and cloud-native applications.
- Strong understanding of databases, data modeling, and system architecture.
- Experience working with real-time systems, event-driven architectures, or asynchronous processing.
- Ability to operate independently and thrive in ambiguous environments.
- Strong problem-solving skills and systems-thinking mindset.
- Excellent communication skills and collaborative approach to engineering.
Nice to Have- Experience with edge computing, serverless architectures, or distributed platforms.
- Exposure to AI-powered products, LLM infrastructure, or agent-based systems.
- Experience designing highly available systems that support significant scale.
- Familiarity with observability, monitoring, tracing, and incident management practices.
- Experience in startup or high-growth environments.
- Full-stack experience building customer-facing product features.
- Experience helping establish engineering standards in early-stage teams.
This is an opportunity to join a highly ambitious team solving complex technical challenges while building products used by a rapidly growing customer base.
You'll have significant ownership, direct access to decision-makers, meaningful influence on architecture and product direction, and the opportunity to work alongside exceptional engineers in a collaborative onsite environment.
