我们重视的品质
责任感
你从头到尾负责问题。你行动迅速，像主人一样行事，并在不确定性中茁壮成长。你之前领导过复杂的项目，无论是否正式，现在准备好再次这样做。

你像用户一样思考，而不仅仅是工程师。你关心你的系统如何创造真实的客户价值——以及如何让它们变得更好。
对“事情的常规做法”保持健康的怀疑态度。
你带来严谨和创造力。最佳实践很重要——但永远不比前进更重要。
你将做的事情

- 使用AI代理通过定义工作范围、编写提示和验证输出来实现多文件更改
我们寻找的人选
- 7年以上在Go（或类似静态类型语言）中构建可扩展、分布式系统的经验
- 熟悉云原生环境（AWS、GCP）
- 熟悉关系型数据库（我们使用MySQL），并了解性能权衡
- 有可观测性工具和生产系统运维的经验
- 倾向于行动而非追求完美，并为技术决策感到自豪
薪酬与福利

Hi, I’m Paul, VP of Engineering at Customer.io. We’re looking for experienced backend engineers who care deeply about reliability, performance, and scalability. You’ll design, build, and evolve the systems that power communication at massive scale - while helping us push the boundaries of what great engineering can look like.
About Customer.io
Over 9,000 companies - from scrappy startups to global brands - use our platform to send billions of emails, push notifications, in-app messages, and SMS every day. Customer.io powers automated communication that people actually want to receive.
We help teams send smarter, more relevant messages using real-time behavioral data. Under the hood: Go, React, Ember and AI help us ship fast and scale with confidence.
What We Value
Ownership
You own problems end to end. You move fast, act like an owner, and thrive in ambiguity. You've led complex projects before, whether officially or not, and you're ready to do it again.
Engineers with product taste
You think like a user, not just an engineer. You care how your systems power real customer value - and how to make them better.
A healthy skepticism for “the way things are done.”
You bring rigor and creativity. Best practices matter - but never more than forward motion.
What You’ll Do
- Design and build distributed systems in Go that help customers send timely, relevant messages at scale
- Collaborate across teams to debug issues and deliver reliable solutions
- Own problems end to end - from architecture and schema design to testing, deployment, and monitoring
- Share knowledge and raise the bar through sharing your progress publicly with short videos, thoughtful writing, and mentorship
- Use AI agents to make multi-file changes by scoping the work, writing the prompt, and verifying the output
What we're looking for
- 7+ years of experience building scalable, distributed systems in Go (or similar statically typed languages)
- Comfort working in cloud-native environments (AWS, GCP)
- Familiarity with relational databases (we use MySQL) and an understanding of performance tradeoffs
- Experience with observability tooling and operating production systems
- A bias for action over perfection, and pride in owning technical decisions
Compensation & Benefits
We believe in transparency. Starting salary for this role is $150,000 - $200,000 USD (or equivalent in local currency) depending on experience and subject to market rate adjustment.
We know our people are what make us great, and we’re committed to taking great care of them. Our inclusive benefits package supports your well-being and growth, including 100% coverage of medical, dental, vision, mental health, and supplemental insurance premiums for you and your family. We also offer 16 weeks paid parental leave, unlimited PTO, stipends for remote work and wellness, a professional development budget, and more.

Our Process
No gotchas, no trick questions - just a clear, human process designed to help both of us make an informed decision.
- Application - We review everyone with care. Tell us why you're interested.
- Recruiter Call (30 mins) - Let’s chat about what you’re looking for and how we work.
- Hiring Manager Interview (60 mins) - Talk with one of our hiring managers about your working style and a project you've owned end-to-end, plus a short AI-assisted coding exercise.
- Technical Interview (60 mins) - A collaborative system design conversation focused on scaling challenges.
- Take-Home Assignment - Complete a short, realistic task similar to what you’d work on here.
- Assignment Review Call (60 mins) - Walk us through your work and discuss tradeoffs, priorities, and how you’d iterate.
All final candidates will be asked to complete a background check and employment verifications as part of our pre-employment process.
Customer.io recognizes the stifling impact of systemic injustice on diverse communities. We commit to using our influence to increase inclusion and equity within the tech industry. We strive to build an inclusive team culture, implement bias-free hiring practices, and develop community partnerships to expand our global impact.
Zoom is the only video conference platform that we use, virtual interviews will be conducted using the video capability (i.e., not via the chat), and offers will be extended in writing on official Customer.io letterhead. Please be vigilant in all of your job search activity, and if you have any questions please contact jobs@customer.io.

We believe in empathy, transparency, responsibility, and, yes, a little awkwardness. If you’re excited by what you read and want to build software that makes communication better for everyone—apply now.
