Job Description

Kiddom’s Tooling team builds and maintains the core systems that empower all engineering teams to deliver reliable, scalable, and efficient software. As a Senior Backend Engineer on this team, you’ll focus on developing backend services, automation frameworks, and internal developer tools that improve the velocity and reliability of our entire platform. You’ll play a key role in shaping how Kiddom engineers build, deploy, and observe systems at scale — with an emphasis on clean, maintainable, and testable code written primarily in Python, and secondary exposure to GoLang.

Job Responsibility

  • Design, build, and maintain backend services and automation tooling primarily in Python, with opportunities to contribute to GoLang-based systems
  • Develop and maintain internal APIs, asynchronous task frameworks, and services that improve developer productivity and platform reliability
  • Collaborate cross-functionally with other engineering teams to understand their needs and build internal systems that streamline workflows
  • Optimize and maintain integrations with internal and external systems, including CI/CD pipelines, observability tools, and developer infrastructure
  • Own projects end-to-end — from system design and architecture to implementation, deployment, and monitoring
  • Drive engineering excellence through thoughtful code reviews, automated testing, and performance optimization
  • Champion modern backend practices — including observability, scalability, and fault tolerance — within the Tooling ecosystem
  • Mentor junior engineers and contribute to shaping the future of Kiddom’s backend and infrastructure practices

Requirements

  • BS or MS in Computer Science or a related field
  • 6+ years of professional experience designing, building, and maintaining backend systems at scale
  • Deep expertise in Python, including experience building APIs and asynchronous processing systems
  • Familiarity with GoLang, with an interest in contributing to Go-based services and tooling
  • Strong proficiency with both relational and non-relational databases (e.g., PostgreSQL, MySQL, MongoDB, Redis)
  • Hands-on experience with distributed systems and microservices architecture
  • Production experience on cloud platforms (AWS, GCP, or Azure), including Docker, Kubernetes, and IaC (Terraform, etc.)
  • Solid understanding of design patterns, testing, and backend performance tuning
  • Strong debugging and system observability skills
  • Collaborative mindset and ability to work effectively with product managers, frontend teams, and other stakeholders
  • Excellent communication skills — written, verbal, and architectural documentation
  • Desire to mentor and elevate team members’ technical skills
  • Passion for improving K–12 education and building systems that serve teachers, students, and educational equity

What we offer

  • Competitive salary
  • Meaningful equity
  • Health insurance benefits: medical (various PPO/HMO/HSA plans), dental, vision, disability and life insurance
  • One Medical membership (in participating locations)
  • Flexible vacation time policy (subject to internal approval). Average use 4 weeks off per year
  • 10 paid sick days per year (pro rated depending on start date)
  • Paid holidays
  • Paid bereavement leave
  • Paid family leave after birth/adoption. Minimum of 16 paid weeks for birthing parents, 10 weeks for caretaker parents. Meant to supplement benefits offered by State
  • Commuter and FSA plans
