Are you ready to join the Un-carrier movement?
We are looking for a Senior Cloud Architect to join the Customer Hub (CHUB) team in DSG's Customer domain. This is a strategic and hands-on role focused on evolving CHUB’s architecture to support modern, scalable, and cloud-native systems.
As a senior technical leader, you’ll drive solution design across multiple initiatives, working closely with product managers, engineers, and SREs to craft systems that are resilient, performant, and aligned with business goals. You'll play a key role in our cloud modernization journey, leveraging AWS services to transform legacy systems and embed standard processes into the team’s day-to-day engineering.
You’ll have the opportunity to influence architecture decisions across a large-scale customer data platform, mentor engineers on cloud-native patterns, and contribute to the long-term technical roadmap that underpins customer experience across DSG.
We are a team that encourages innovation and advocate an agile and open approach, truly working and playing in the Un-carrier way!

Job Responsibilities:

• Provide architectural leadership during the product intake phase—evaluating options, identifying risks, and helping define scalable solution designs.
• Own solution architecture across multiple parallel initiatives, ensuring design consistency and quality across CHUB components.
• Own the modernization of CHUB systems by driving cloud-native design and migration strategies using AWS services (e.g., RDS, Lambda, DynamoDB, Step Functions, Elasticache, Opensearch).
• Establish reusable cloud reference architectures aligned to AWS Well-Architected Framework and CHUB's technical vision.
• Partner with engineering, SRE, and platform teams to implement cloud infrastructure and services using Infrastructure as Code (IaC) and CI/CD automation.
• Coach and mentor engineers across CHUB in cloud architecture, security, resiliency, and observability practices.
• Participate in and lead design reviews, documentation efforts, and architectural governance processes.
• Promote technical excellence through mentorship, sharing knowledge and best practices, and documentation of architectural decisions.

Secondary Responsibilities

• Support cloud cost optimization and recommend improvements to increase operational efficiency.
• Participate in incident reviews and root cause analysis for cloud-based systems.
• Collaborate with DSG’s central architecture and security teams to ensure compliance with enterprise standards.
• Evaluate new cloud technologies and tools, and advocate for their adoption where appropriate.

Desired Experience and Skills

• 8+ years of experience in software engineering and architecture roles with 3+ years passionate about AWS cloud solutions.
• Strong experience designing scalable distributed systems, microservices, and event-driven architectures.
• Hands-on experience with AWS services such as RDS, Lambda/Step Functions, S3, DynamoDB, ElastiCache, Elasticsearch, and Neptune.
• Proficiency with Infrastructure as Code tools (Terraform, CloudFormation), CI/CD pipelines, and Git-based workflows.
• Proven understanding of cloud security, scalability, high availability, and cost optimization principles.
• Background in Java/Spring Boot or similar frameworks; experience refactoring legacy apps for cloud-readiness is a plus.
• Sophisticated user in observability tools (e.g., Splunk, SignalFX, CloudWatch, Prometheus, Grafana).
• Strong communication and leadership skills; able to influence technical direction across teams.

Education

• Bachelor's degree in Computer Science, Information Systems, or a related technical field—or equivalent practical experience.
• AWS Certified Solutions Architect – Professional (or equivalent hands-on expertise) strongly preferred.
• Continued education through technical certifications, bootcamps, or open-source contributions is valued.
