## 💻 **Role**
The Messaging Platform team builds the systems that help teams across Whatnot deliver the right message to the right buyer or seller at the right time. They power communications across push notifications, email, SMS, and in-app messaging experiences, and we’re evolving from a delivery platform into a broader messaging and engagement platform.
As a Backend Engineer on Messaging Platform, you will build the backend systems, APIs, and platform capabilities that make messaging at Whatnot reliable, scalable, intelligent, and measurable. You’ll work on problems at the intersection of product, platform, and infrastructure: from audience targeting and campaign scheduling to notification settings, experimentation, observability, and the services that power high-volume sends across multiple channels.
This is a strong fit for an engineer who enjoys shipping product-facing platform work, cares deeply about user trust and message quality, and is excited by the challenge of building systems used by many teams across the company.
As a Backend Engineer on this team, you will:
- Build and evolve scalable backend services and platform primitives that power push, email, SMS, and in-app messaging.
- Design systems for audience targeting, campaign scheduling, content orchestration, delivery workflows, and messaging preferences.
- Improve reliability, performance, and observability for high-volume, business-critical messaging systems.
- Partner closely with product, design, data science, and other engineering teams to build messaging experiences that drive engagement while respecting user trust and platform quality.
- Create clean APIs, abstractions, and operational patterns that allow teams across Whatnot to launch messaging use cases safely and efficiently.
- Contribute to experimentation, attribution, and measurement foundations so teams can understand the impact of messaging investments.
- Help raise the bar on engineering quality through strong technical judgment, thoughtful code reviews, and solid operational habits.
- Contribute to team-wide ownership of production health, incident response, and continuous improvement of platform reliability.
**We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection. Team members in this role must live within commuting distance of our New York or San Francisco hub.**
## 👋 **You**
People who do well at Whatnot tend to be comfortable figuring things out as they go, biased toward action, and genuinely curious about what they're building. They care more about outcomes than credit and stay close to the product and the people using it.
As our next Backend Engineer you should have:
- Bachelor’s degree in Computer Science, a related field, or equivalent practical experience.
- 4+ years of professional software engineering experience building and shipping backend systems in production environments.
- Strong experience designing, building, and operating scalable, maintainable backend services.
- Strong technical judgment and the ability to make thoughtful tradeoffs between speed, quality, reliability, and long-term maintainability.
- Experience working in fast-moving, cross-functional product or platform environments.
- Comfort owning ambiguous problem spaces and turning them into clear technical plans and shipped outcomes.
- Strong communication and collaboration skills, especially when partnering across engineering, product, design, and data.
- A product-minded approach to engineering — you care not just about whether a system works, but whether it creates value for users and partner teams.
Nice to have:
- Experience with messaging, notifications, lifecycle, CRM, or engagement platforms.
- Experience building distributed systems, event-driven architectures, or high-throughput asynchronous workflows.
- Familiarity with experimentation, attribution, ranking, personalization, or recommendation-adjacent systems.
- Experience improving observability, alerting, and operational excellence for production systems.
- Familiarity with modern backend stacks such as Python, Elixir, or JavaScript/TypeScript.
- Experience building products in marketplace, social, creator, or consumer environments.
