- ## About the Role
You will own the backbone that runs thousands of concurrent AI-powered phone calls inside bank-grade on-premise environments. Not just keeping pods alive, you architect distributed systems that handle real-time voice, scale STT / LLM / TTS inference across customer GPU clusters, integrate with enterprise telephony (Cisco CUBE, Genesys, Asterisk), and deploy behind the firewalls of largest financial institutions. Your work decides whether our platform answers a bank's rush-hour traffic or leaves customers on dead air.
## What You'll Do
* • **Own on-prem deployments** into OpenShift clusters inside banks. Helm charts, image registries, GPU allocation, CyberArk integration, SAML 2.0 / OIDC SSO.
* • **Scale GPU inference infrastructure** for our STT, TTS, and LLM models across multiple customer environments (H100 / H200, NVLink, Triton or vLLM).
* • **Integrate with telephony**: Asterisk, SIP trunks, Cisco CUBE, Genesys, WebRTC. SIP header parsing (X-Genesys-\*), direction routing, warm transfers, DTMF.
* • **Own reliability**: Splunk SIEM forwarding, Langfuse and Grafana observability, incident playbooks for bank-grade 24/7 SLAs.
* • **Security and compliance**: RBAC, pentest remediation, KVKK and BDDK compliance patterns, pod security policies.
* • **Scale with growth**: we onboard a new bank or insurer every quarter. Each is a new on-prem environment with its own constraints.
* • **Spot flaws early**. We are building new architecture for a regulated industry. You help us see what needs to be solved next.
## Interesting Problems to Own
* • **On-prem meets streaming**. Most voice AI stacks assume cloud. We run the same stack inside banks with zero internet egress. Novel problems in image delivery, model updates, secrets rotation.
* • **Bank-scale concurrency**. A single campaign can put millions of customers on the line the same afternoon. Queueing, graceful degradation, GPU-aware autoscaling are yours to design.
* • **Legacy-meets-new telephony**. Cisco CUBE, Asterisk, Genesys, SIP, WebRTC. You wrangle old-school protocols alongside modern streaming stacks.
## What Makes You a Great Fit
* • **3+ years** building and scaling distributed systems. Deep Kubernetes / OpenShift knowledge. AWS / GCP helpful.
* • **Fundamentals plus**. You can sketch how a SIP INVITE flows through a proxy, explain a K8s GPU scheduler, or tell us the obscure thing you fell asleep reading last night.
* • **Real-time systems** experience. Low-latency streaming or inference. Voice / video is a big plus.
* • **On-prem mentality**. You have shipped software into environments you did not fully control: Turkish bank, European healthcare, US regulated finance, anything similar.
* • **Startup hats**. You have worked where problems find you before process does.
* • **Opinionated without alienating**. Opinions drive progress, but you find compromises with customers and teammates.
* • **Familiar with**: Kubernetes / OpenShift, Helm, Docker, Terraform, NVIDIA GPU stack, Asterisk, SIP, Cisco CUBE, Genesys, Splunk, Grafana, CyberArk, Python or Go.
## Bonus Points
* • Telephony systems (SIP, VoIP, WebRTC).
* • ML infrastructure, model serving, or GPU computing (Triton, vLLM, TensorRT).
* • Real-time audio processing.
* • Banking / fintech / BDDK and KVKK compliance familiarity.
* • Fluent Turkish or comfortable working with Turkish customer teams daily.\

_Don't worry about the checklist. We hire for how you think, not how many boxes you tick. The work is hard, the hours_
_are long, and most of what we ship nobody has built before. If that sounds good instead of scary, apply._
