YOUR MISSION: As a Forward Deployed Engineer, VoIP your mission is to make Parloa work flawlessly in the real world of enterprise telephony. You are the deep VoIP/SIP expert embedded in our most critical customer integrations—owning the end-to-end technical path from “a phone rings” to “the bot answers,” across carriers, SIP trunks, SBCs, networks, and enterprise constraints. You’ll operate where product, infrastructure, and customer reality meet: diagnosing tricky call flows, designing robust connectivity patterns, unblocking go-lives under pressure, and shaping how Parloa integrates with telephony ecosystems—both for customers and partners. IN THIS ROLE YOU WILL: - Own telephony integration projects: Lead the technical execution of VoIP/SIP connectivity for enterprise customers and partners (PoCs through production). - Design reliable call paths: Architect integrations via SIP trunking providers, direct trunks, or enterprise telephony infrastructure—balancing latency, reliability, and security constraints. - Debug complex issues end-to-end: Troubleshoot signaling and media problems (e.g., routing, codecs, DTMF, call transfers, failover), using logs and network traces to find root cause fast. - Navigate enterprise constraints: Propose connectivity options when customers have strict firewall policies, limited exposed ports, or regulatory/security requirements. - Partner deeply with customer engineers: Work directly with telecom, network, and platform teams to align architectures, test plans, and operational procedures. - Support partner enablement: Help telephony partners integrate with Parloa, resolve escalations, and improve repeatability through patterns, tooling, and documentation. - Engineer pragmatic solutions: Build small utilities, scripts, or lightweight services when needed to validate assumptions, automate diagnostics, or close integration gaps. - Raise the bar on reliability: Define best practices for NAT traversal, resiliency, monitoring, and incident response in telephony-connected deployments. - Shape the product: Translate field learnings into clear feedback for core engineering—turning recurring integration pain into platform improvements. WHAT YOU BRING TO THE TABLE: - 5+ years of professional experience in VoIP/telephony engineering, SIP integrations, telecom consulting, or adjacent roles with direct customer impact. - Strong hands-on expertise with SIP-based integrations, call routing concepts, and real-world troubleshooting across networks and enterprise environments. - Solid understanding of signaling vs. media flows, common failure modes, and diagnostic approaches (logs, SIP traces, packet captures). - Practical experience working with SIP trunking providers, SBCs, enterprise PBX/contact center setups, or similar telecom infrastructure. - Comfort operating in ambiguous, high-responsibility situations—able to own issues end-to-end and drive them to resolution with multiple stakeholders. - Ability to communicate clearly with both engineers and non-telephony stakeholders, turning complex call-flow topics into actionable decisions. - Builder mindset: you don’t just explain problems—you design the fix, validate it, and make it repeatable. - Degree in Computer Science, Engineering, or a related field (or equivalent practical experience). - Strong plus: Cloud-native experience (especially Azure), Kubernetes environments, and/or building integration tooling in a scripting or backend language. WHAT'S IN IT FOR YOU: - Join a diverse team of 40+ nationalities with flat hierarchies and a collaborative company culture. - Opportunity to build and scale your career at the intersection of customer-facing roles and engineering in a dynamic startup on its journey to become an international leader in SaaS platforms for Conversational AI. - Deutschland ticket, Urban Sports Club, Job Rad, Nilo Health, weekly sponsored office lunches. - Competitive compensation and equity package. - Flexible working hours, 28 vacation days, and workation opportunities. - Access to a training and development budget for continuous professional growth. - Regular team events, game nights, and other social activities. - Work from home and/or our beautiful office in London with adjustable desks, social areas, fresh fruits, cereals, and drinks.
