DevOps Engineer

Istanbul, İzmir, or Remote (Türkiye)

At Freya, we build voice AI call centers for regulated industries: banks, insurance, and enterprise call centers. We are backed by Y Combinator (S25) and have raised $3.5M from including investors like Y Combinator, our agents answer real customer calls in on-prem environments inside banks.

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.

• • 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.

• • 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.

• • 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.

• • 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.

Email [email protected] with a short note about the hardest infra problem you have shipped and your CV. We move fast, expect a reply within 48 hours. Fluency in Turkish and English is a requirement for this role.

If you don't have the perfect experience that is fine! We're a bunch of drop-outs and hackers. Working at a start-up is really hard. We work a lot and we figure things out on the fly.
