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
