- 设计并扩展我们的平台基础架构，以支持来自全球的数十万商户
- 与其他团队协调工作范围，以交付跨团队项目
- 指导其他工程师，确保他们的开发与成长
- 与工程经理和团队负责人合作，推动并执行团队的长期愿景
- 以有洞察力和前瞻性的方式执行针对广泛或复杂需求的技术战略，超越直接团队解决大型开放性问题
- 使用代理开发工具如Claude Code来自动化部分开发流程
- 提升整个组织的工程标准、工具和流程
我们寻找：
- 5年以上后端软件工程师经验
- 对领域驱动设计、分布式系统以及架构决策如何影响性能和可维护性有深刻理解
- 精通数据模型、API设计（HTTP和RPC）、状态机、事件驱动架构和数据库设计
- 优秀的沟通能力，包括书面和口头表达。必须熟练进行异步沟通——编写技术规范、ADR、项目计划等
- 有设计、开发和发布后端系统的经验（我们的技术栈：AWS、gRPC、Snowflake、Kotlin、Python、MySQL、Kubernetes）。Java和Kotlin经验尤其有用

At Affirm, we exist for the moments that matter—giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most.
The Merchant & Partner Lifecycle (M&PL) team is at the forefront of Affirm’s architectural transformation. We are addressing critical architectural risks by consolidating merchant lifecycle orchestration into a newly cohesive domain.
You will act as a technical leader responsible for building out the brand new lifecycle-orchestrator service that’s at the heart of multiple connected systems. Your work will deliver immediate availability improvements through system simplification and isolation, and modernize older parts of the codebase.
What You'll Do
- Design & expand the backbone of our platform to scale to hundreds of thousands of merchants from all around the world
- Design and align the scope of work with other teams to deliver cross-team projects
- Mentor other engineers to ensure their development & growth
- Partner with Engineering Manager and Team Lead to drive and execute the long-term vision of the team
- Execute technical strategy for broad or complex requirements with insightful and forward-looking approaches that go beyond the direct team and solve large open-ended problems
- Utilize agentic development tools like Claude Code to automate parts of the development process
- Improve engineering standards, tooling, and processes throughout the organization
What We Look For
- 5+ years of experience as a backend software engineer
- A strong understanding of Domain-Driven Design, distributed systems, and how architectural decisions affect performance and maintainability
- Proficiency with data models, API design (http and RPC), state machines, event-driven architecture, and database design
- Excellent communication skills, both written and verbal. Must be proficient in asynchronous communication–written tech specs, ADRs, project plans, etc.
- Experience designing, developing, and launching backend systems (our stack: AWS, gRPC, Snowflake, Kotlin, Python, MySQL, Kubernetes). Java and Kotlin experience are especially helpful.
- Prior experience with monitoring and alerting systems (sentry.io, rollbar, chronosphere, kibana)
