Position SummaryAs a Sr Software Development Engineer on the SMS team, you will design, build, and operate distributed systems that power large-scale, real-time text messaging for CVS Health members. You'll work within a collaborative, product-oriented engineering team responsible for the full lifecycle of our messaging platform - from message orchestration and carrier integration to delivery tracking, opt-in/opt-out compliance, and analytics. This role is well suited to an engineer who enjoys solving problems in high-throughput, low-latency systems while keeping reliability and compliance front and center.
Responsibilities- Design, develop, and maintain scalable services that support inbound and outbound SMS/MMS delivery for member communications
- Build integrations with SMS carriers/aggregators and messaging APIs (e.g., Twilio, Syniverse, or similar), including delivery receipts, retries, and failover handling
- Ensure platform compliance with TCPA, CTIA, and carrier messaging guidelines, including opt-in/opt-out and consent management logic
- Partner with product, compliance, and clinical/pharmacy stakeholders to translate messaging requirements into resilient technical designs
- Own service reliability: monitoring, alerting, on-call support, and root-cause analysis for production issues in a high-volume messaging environment
- Optimize for throughput and latency across queuing, rate-limiting, and delivery-confirmation pipelines
- Write clean, testable, well-documented code and participate actively in code reviews and design discussions
- Contribute to architectural decisions around microservices, event-driven design, and API contracts within the messaging ecosystem
- Mentor junior engineers and contribute to raising the technical bar across the team
Required Qualifications- 5+ years of experience in software development, including a mix of front-end and back-end technologies within a product-oriented, cross-functional engineering team
- Strong foundation in software engineering fundamentals: problem solving, data structures, algorithms, design patterns, and concurrency
- Hands-on experience with one or more of: Java, C#/.NET, or similar backend languages, plus experience with distributed messaging/queueing systems (e.g., Kafka, SQS, RabbitMQ)
- Experience integrating with third-party SMS/messaging or telephony APIs (e.g., Twilio, carrier aggregators) is strongly preferred
- Strong SQL skills and understanding of relational databases (e.g., SQL Server, PostgreSQL)
- Solid understanding of microservice architecture and API design
- Experience designing, implementing, and operating distributed systems at scale
- Clear, effective written and verbal communication skills
Preferred Qualifications- Experience with regulatory/compliance requirements for text messaging (TCPA, CTIA short code guidelines) or another regulated communications domain
- Experience with cloud platforms (AWS, Azure, or GCP) and containerized deployments (Docker/Kubernetes)
- Familiarity with observability tooling (e.g., Datadog, Splunk, Grafana) for high-volume production systems
- Bachelor's degree in Computer Science or related field, or equivalent practical experience
EducationBachelor's degree or equivalent work experience in Mathematics, Statistics, Computer Science, Analytics, Engineering, or related discipline. Master's degree preferred
