About The Position

Telegent is hiring a Senior Software Engineer to build its AI-native mobile network platform, enabling programmable workflows on real mobile numbers, including messaging, voice, and carrier integrations. The role delivers new capabilities across SMS, MMS, RCS, voice, and carrier services while extending the established target architecture and retiring replaced legacy workflows without downtime.

The engineer owns features end to end, from design through testing, release, rollout and rollback planning, and production monitoring. The work includes building reliable services at scale, selecting and using appropriate data stores, monitoring performance and failure behavior, and working with engineering leadership on architecture decisions and risks.

The platform includes relational, wide-column, analytics, ledger, cache, and object stores, plus event streaming. Telegent works AI-first, using agent-driven design and implementation, and emphasizes small, versioned, reversible changes behind pull requests with CI, end-to-end ownership, and security and SOC 2 controls from the start. The first deliverable is an assessment and 100-day plan.

Requirements

• Track record of shipping customer-facing services and APIs at scale, from design through production.
• Deep, hands-on experience with transactional, wide-column, streaming, analytical, ledger, cache, and object stores, including sound judgment about when to use each.
• Experience with distributed-systems reliability, including replication, consistency, sharding, read and write access patterns, and RPO and RTO considerations.
• Cloud and infrastructure experience, with Azure as the primary cloud and experience with multi-region and multi-provider deployments.
• Fluency in TypeScript for product development, services, and APIs; Go for high-throughput services; and SQL.
• Experience practicing enterprise-grade agentic coding rather than vibe coding, with the ability to work across coding clients and harnesses.
• Arrive with a personal setup of agents, skills, and automations, and ideas for improving Telegent's setup.
• Ability to take work from idea to production without hand-offs, raise problems early, and help keep the team on track.
• End-to-end systems lifecycle and full-stack development mastery.
• Experience building apps and services on an established architecture and owning work end to end.
• Mastery of agentic coding, including worktree management and multi-agent workflows; skills, hooks, and routines; coding clients and custom harnesses; token optimization and plan mode; and structured approaches such as SDD, TDD, SpecKit, and role-based development.
• Experience deploying systems at scale using agentic coding and distinguishing enterprise-grade practices from vibe coding.

Nice To Haves

• Experience with telecom or messaging platforms, including SMS, MMS, SIP, or carrier integrations.
• Production experience with CQRS and event-driven designs.
• Experience with billing or ledger systems where every entry is append-only and auditable.
• Experience building to SOC 2 controls from the first line of code.
• Rust or C/C++ experience for performance-critical paths in the ledger and data plane.

Responsibilities

• Deliver the product roadmap by designing, building, and shipping messaging, voice, and carrier-integration capabilities as services on the new platform.
• Build on the target architecture, choosing appropriate data stores and following or extending established patterns and standards.
• Own features end to end, including design, testing, release, production monitoring, and rollout and rollback plans.
• Maintain service reliability at scale by monitoring performance and failure behavior as partners and traffic grow, and addressing bottlenecks.
• Retire legacy workflows when their replacement features move to the new platform, without downtime.
• Work with engineering leadership on architecture decisions, raise risks early, and maintain standards for small, versioned, reversible changes behind pull requests with CI.
• Collaborate with engineering, product, and leadership in an AI-native environment and contribute to team learning and standards.
• Prepare an initial assessment and 100-day plan.
