Responsibilities
- Drive the architecture, design, and implementation of the Communications Platform’s platforms — including Email Delivery, In-Product Notifications and Push Notifications.
- Define and own the technical strategy for platform modernization, reliability hardening, and engineering standards across backend services.
- Provide hands-on technical leadership and mentorship to a team of backend and frontend engineers, helping them grow in system design, decision-making, and ownership.
- Write high-quality Java code and stay close to execution — leading design reviews, code reviews, and architectural decisions that raise the bar across the codebase.
- Proactively identify and address systemic risks in performance, reliability, security, and operability before they become incidents.
- Serve as a key technical partner on cross-team and company-wide architecture initiatives.
- Balance short-term delivery with long-term platform health, communicating tradeoffs clearly to stakeholders and leadership.
Requirements
- 10+ years of backend engineering experience, with significant time building and operating large-scale, customer-facing systems.
- Deep expertise in Java and backend service development, including APIs, async processing, messaging systems (ex: Kafka), and data stores (ex: MongoDB, CockroachDB).
- Strong experience with distributed systems in production — including reliability, scaling, failure modes, and observability.
- A proven track record of technical leadership at the Staff or Senior-plus level, influencing architecture across multiple teams or services.
- Experience evolving existing systems — modernizing legacy platforms, simplifying complexity, and strengthening reliability without unnecessary rewrites.
- Experience operating within platform engineering contexts, where your customers are internal or external product teams and the quality of your APIs and abstractions directly shapes their velocity.
- A strong understanding of multi-channel communication infrastructure (email delivery, push, in-product notifications) is a meaningful plus.
- The ability to communicate complex technical concepts clearly to both technical and non-technical partners.
- A mindset oriented toward mentorship, collaboration, and inclusive technical leadership.
