About the Role

We're seeking a highly skilled Senior Backend Engineer to join our team at Dynamism VC. As a key member of our engineering team, you'll play a crucial role in shaping the system architecture behind our high-growth startup's most important products.

As a Senior Backend Engineer, you'll lead the design and implementation of complex backend systems using TypeScript/Node, like high-availability ingestion pipelines and A/B testing platforms. You'll also mentor junior engineers, set best practices, and solve challenging technical problems.

This is a high-impact role that will directly influence the stability and scalability of our core infrastructure. You'll work closely with our founders to align technical initiatives with our company vision and product roadmap.

Key Responsibilities
  • Design and build an analytics ingestion pipeline using Kafka, ClickHouse, and Redis, ensuring >99.99% uptime for real-time data processing.
  • Build an A/B testing platform using Cloudflare Workers, enabling data-driven user experience optimization.
  • Enhance our CI/CD platform to improve build stability and automate deployment pipelines for seamless feature integration.
  • Deploy a multi-tenant Next.js app on Cloudflare with automatic revalidation for fresh, up-to-date content delivery.
  • Mentor junior engineers, promoting best practices in development and architecture.
  • Collaborate with founders to align technical initiatives with company vision and product roadmap.
  • Manage infrastructure to ensure scalability and security in technical architecture, supporting a growing user base.
Requirements
  • 5+ years of experience working with production distributed systems and service-oriented architecture.
  • Deep knowledge of load balancers, databases, queuing, caching, HTTP, APIs, high availability, fault tolerance, and redundancy.
  • Proficient in TypeScript, with experience in Python, Go, or Java, and a readiness to work with TypeScript/Node.
  • Familiar with React and comfortable handling frontend tasks as needed.
About You
  • You have an 'Always Shipping' mentality, preferring to iterate quickly rather than get bogged down in prolonged planning cycles.
  • You're product-focused, always considering how features impact customer experience and satisfaction.
  • You value writing clean, maintainable, and well-documented code, knowing that clear documentation is essential for long-term success over quick fixes.
  • You have faced deployment and maintenance crises in the past, giving you strong, well-formed opinions on building products that are reliable and scalable.
  • You're comfortable with ambiguity, preferring to define software architecture patterns that directly address customer pain points rather than relying on one-size-fits-all solutions.
What We Offer
  • Competitive salary: $180k - $250k
  • Seed-level equity (at Series A stage company)
  • Benefits: Health, dental, and vision insurance
  • Work environment: In-office with a flexible, hybrid work model
