• Onboard and test new supplier connections (SMPP/MM4/MM7 protocols) in coordination with Connectivity Operations

• Identify and escalate carrier degradations, encoding errors, and throughput issues, coordinating resolution with CORT and suppliers

• Contribute to automation initiatives that improve supplier onboarding times, cost management, and quality alerting

• Participate in regional handover processes and maintain clear handover notes for the next-shift team

• Support the migration of SMS services from IBM Data Centres to AWS

What You Will Bring

• Solid understanding of SMS routing fundamentals SMPP protocol, DLR codes, encoding, conversion rates, and delivery ratio metrics

• Experience working with carrier or telco routing systems and monitoring tools (e.g. Tableau, Zendesk, or equivalent)

• Analytical mindset with the ability to investigate degradation patterns, cross-reference data sources, and drive root-cause resolution

• Comfortable working in a fast-paced, 24×5 operational environment with on-call responsibilities

• Strong written and verbal communication skills; able to coordinate clearly across time zones with suppliers and internal stakeholders

• Experience collaborating cross-functionally with carrier, product, and engineering teams

Nice to Have

• Familiarity with voice routing metrics (ASR, NER, MOS, PDD) and SIP fundamentals

• Experience with ML-driven or algorithmic routing systems

• Knowledge of RCS, Network APIs, or US direct carrier connectivity

• Background in a CPaaS, wholesale telco, or carrier operations environment

About the Team

The Technical Routing & Quality team is focused on three objectives: reducing tech debt, automating the core business, and investing in growth areas such as Network APIs, RCS, and US direct connectivity.
