Principal Software Engineer

Tóm tắt công việc
As a Product Engineer, you will drive outcomes across the team and technical system by leading design, implementation, rollout, and operational excellence. You will work primarily in our Ruby on Rails codebase to deliver product features end-to-end. We also have services written in Java/Kotlin, and you may occasionally contribute fixes or improvements there when needed.
Key Responsibilities
1. Technical Leadership
Ruby on Rails: Design, develop, and operate backend features in a Ruby on Rails and core services, with strong software engineering fundamentals and pragmatic delivery.
API & Services: Design and evolve RESTful APIs and service boundaries with clear tradeoffs and maintainable interfaces.
Data & Performance: Model data effectively and optimize SQL performance; identify and address bottlenecks and system inefficiencies.
Cloud-Native Delivery: Architect and operate cloud-native applications on AWS (and related tooling) with pragmatic use of Docker/Kubernetes where appropriate.
Operational Excellence: Improve observability (logs/metrics/traces), incident response, and post-incident learning to raise system reliability.
2. Delivery Ownership & Cross-Functional Collaboration
End-to-end Delivery: Own delivery from problem definition through production rollout, ensuring quality and operational readiness.
Stakeholder Collaboration: Partner with Product, Design, QA, and DevOps to clarify requirements, reduce ambiguity, and deliver outcomes aligned to business goals.
Release Management: Plan and execute production releases, coordinate stakeholders, and continuously improve deployment safety and speed (CI/CD)
3. Engineering Excellence & Quality
Code Quality: Set and model best practices for clean, maintainable code; lead strong code review culture.
Testing & Automation: Increase confidence and reduce manual testing via effective automated tests and robust review processes.
CI/CD: Operate and improve CI/CD pipelines (CircleCI/GitHub Actions or similar) to support frequent and safe delivery.
Security & Scalability: Ensure AI-assisted speed never compromises security, privacy, scalability, or compliance requirements.
4. AI-Assisted Delivery Practices
Rapid Iteration: Use AI to speed up prototyping and iteration (requirements exploration, code scaffolding, test generation, refactoring).
Verification & Governance: Quickly identify flaws in AI-generated output and correct them; maintain strong human verification habits (testing, reviews, threat modeling).
AI-Friendly Documentation: Improve the clarity of logs, runbooks, and technical documentation so both humans and AI tools can understand and operate the system effectively.
Scope & Collaboration
Primary focus is Rails-first backend/API delivery, with pragmatic cross-functional reach (infra/observability/quality) as needed to unblock outcomes.
You will collaborate across time zones with global stakeholders and engineering partners.
