Senior Software Engineer (AI-Native)

Telegent is building a programmable mobile network for AI agents. The Senior Software Engineer (AI-Native) will deliver product capabilities across messaging, voice, and carrier integrations, owning services from design through production while keeping the platform reliable and scalable.

Responsibilities:

• Deliver the product roadmap. Design, build and ship new capabilities across messaging (SMS, MMS and RCS), voice and carrier integrations as services on the new platform
• Build on the target architecture. Use the right store for each feature, follow the patterns and standards already set, and extend them where the roadmap needs it
• Own features end to end. From design through testing, release and monitoring in production, including the rollout and rollback plan
• Keep services reliable at scale. Watch performance and failure behaviour as partners and traffic grow, and fix what holds us back
• Retire legacy workflows as you go. When a feature moves to the new platform, switch off the legacy workflow it replaces, with no downtime
• Keep the platform on track. Work with engineering leadership on architecture decisions, raise risks early, and hold the standard: small, versioned, reversible changes behind PRs with CI
• Grow together. Collaborate closely with engineering, product and leadership in an AI-native environment, learning from each other and raising the bar as a team

Requirements:

• Know the end-to-end systems lifecycle and full-stack development inside and out
• Have mastery over agentic coding, including:
• Worktree management vs. multi-agent workflows
• Skills, hooks, and routines
• Flexibility across clients: Claude Code, Cursor, Codex, even custom harnesses like OpenClaw and Hermes
• Token optimization, plan mode, and structured approaches like SDD, TDD, SpecKit, and role-based development
• Have deployed systems at scale with agentic coding, and know the difference between vibe coding and enterprise-grade agentic coding
• A track record of shipping customer-facing services and APIs at scale, from design to production
• Deep, hands-on experience across transactional, wide-column, streaming, analytical, ledger, cache and object stores, and the judgment to use each one well
• Replication, consistency, sharding, and read and write access patterns, with RPO and RTO in mind
• Azure first, plus multi-region and multi-provider deployments
• Fluent in TypeScript for product, services and APIs, and Go for high-throughput services, plus SQL
• You practice enterprise-grade agentic coding, not vibe coding, and you move easily across coding clients and harnesses
• You arrive with your own setup of agents, skills and automations, and ideas on how to make ours better
• You take work from idea to production without hand-offs, raise problems early, and help keep the team pointed in the right direction
• Telecom or messaging platforms: SMS, MMS, SIP or carrier integrations
• CQRS and event-driven designs in production
• Billing or ledger systems, where every entry is append-only and auditable
• Building to SOC 2 controls from the first line of code
• Rust or C/C++ for performance-critical paths in the ledger and data plane
