We are looking for a Lead Backend Engineer to take ownership of our high-performance core responsible for delivering mass notifications via SMS, Email, Voice, Push, Slack, and IPAWS to thousands of users simultaneously. This isn't just about writing code; it’s about engineering resilience. You will be the architect of systems that cannot afford to fail, ensuring that every message reaches its destination with perfect reliability and industry-leading throughput. If you are driven by the challenge of optimizing distributed systems and building SaaS solutions that scale gracefully under usage spikes, your expertise will have a direct, tangible impact on our mission. Candidates must be located within driving distance from our Baltimore HQ.

  • Proven experience designing and maintaining complex, multi-tenant SaaS environments that prioritize uptime and data integrity.
  • Proven experience with both relational (e.g., PostgreSQL, MySQL) and NoSQL (e.g., Redis, DynamoDB, MongoDB) databases, specifically focusing on performance tuning, indexing strategies, and data modeling for scale.
  • A strong background in distributed systems, including experience with message brokers (e.g., RabbitMQ, Kafka) and database optimization.
  • Expert knowledge of monitoring tools and observability practices to ensure 24/7 system health.
  • The ability to articulate complex technical concepts to both technical and non-technical stakeholders while fostering an inclusive, collaborative environment.

Responsibilities

  • Design and evolve a high-throughput notification engine capable of handling massive spikes in data without compromising on latency or reliability.
  • Continuously refine system architecture to meet and exceed strict SLAs, ensuring the engine remains performant as our user base grows.
  • Implement sophisticated monitoring, alerting, and self-healing protocols to identify and resolve bottlenecks before they impact our users.
  • Set the standard for engineering excellence through high-quality code reviews, technical documentation, and proactive mentorship of the engineering team.
  • Design and maintain high-performance database schemas and query structures optimized for rapid ingestion and retrieval of millions of notification records.
  • Build and maintain robust API integrations and asynchronous communication pathways (message queues, event-driven architecture) across diverse notification channels.
  • Transition high-level business requirements into technical roadmaps, focusing on modularity, security, and long-term maintainability.
