Telecom Architect

Telecom Architect – Telecom Infrastructure / OSS-BSS / AI-Native Platform Engineering

Location: Bengaluru (In-Office)
Experience: 5–10 Years
Company: Spenza

Build the Infrastructure Layer for Modern Telecom

Commerce became programmable with Shopify.
Payments became programmable with Stripe.

Telecom is now undergoing the same transformation.

Spenza is building the infrastructure platform that enables Enterprises, OEMs, MVNOs, IoT companies, and distributors to launch and monetize connectivity products without building telecom infrastructure from scratch. We innovate on three fronts to build a vertically integrated telecom company, and the agents sit across all of them:

• Operator-neutral connectivity aggregation platform with mobile plan marketplace - a connectivity marketplace with integrated billing; buy, mix, and manage plans across carriers from one pane. Driver: eSIM adoption
• Agentic OS - agents that automate the full procure-to-pay and operations workflow: planning, provisioning, NOC, support, reconciliation. Driver: AI adoption
• Vertical integration - Control and orchestrate the network layer to match end business use case with real-time spot/dynamic pricing matching demand to operator supply: over-the-air profile switching, remote SIM management, plans created and changed on the fly. Driver: RSP & 5G network slicing.

We are building the modern agentic operating system for telecom commerce:

• Connectivity orchestration
• OSS/BSS workflows
• Billing and rating systems
• eSIM lifecycle management
• Telecom APIs
• Enterprise-grade telecom infrastructure
• Embedded connectivity platforms
• Distributor and reseller infrastructure
• Semi-automated customer support
• Network provisioning
• User onboarding
• Reconcilliation and audit agents
• Marketing agents for operators

Our customers — including Angel Watch, Butlr, and Rocket Phone — use Spenza to bundle telecom services into their products and customer experiences.

Spenza has successfully navigated the 0→1 journey and is now scaling through the 1→10 phase.

If companies like Exotel, Plivo, and Twilio built programmable communications APIs for voice and messaging, Spenza is building the infrastructure layer for programmable connectivity and telecom monetization.

We are looking for a deeply technical, detail-oriented engineering leader who wants to help build a globally credible telecom infrastructure platform from India.

The Opportunity

What you’d build
Fine-tune and adapt models on telecom data — provisioning logs, network topologies, support transcripts, carrier specs — where it beats prompting/RAG.
Design the agent architecture for planning, provisioning, NOC anomaly detection, and support, with the guardrails and evals to run it safely in production.
Deploy into a live environment: our own ops team is the first customer — real traffic and a tight feedback loop from day one, not a pilot you have to go find.
Who you are
A strong engineer from a Tier-1 institute (IIT / BITS / NIT or equivalent) who has shipped in a startup and is comfortable with ambiguity. At least 4-6 years of IC experience with startup stints.
AI-native - you’ve fine-tuned/adapted models for generative AI workflows and built agentic systems.
Full-stack in practice: data pipelines, model training and serving, and the product engineering to put agents in front of customers.
What you’ll gain
Rare, compounding expertise in two fields at once: production agentic-AI deployment — fine-tuning, evals, guardrails, agents running real operations — plus deep telecom domain knowledge: billing, connectivity management, OSS/BSS, SIP/call management, SMS & number management, provisioning, and NOC.
The team, and what’s in it for you
You’d work in our Bangalore office, alongside the founder Vinaychandra Bharadwaj (ex- Tejas Networks, ex MoneyView, MBA- IIMB). This is a founding-level seat: you own the AI direction and hire the team behind you.
