Who We Are
At Conquer , we help go-to-market teams connect more meaningfully, act more effectively, and grow more predictably. As a leader in intelligent revenue engagement, we empower our customers to orchestrate the right message at the right time across every channel.
We believe bold ideas, authentic collaboration, and a growth mindset are essential to conquering your day and your goals. If that excites you, we would love to meet you.
Why This Role Matters
Real-time communication sits at the heart of the Conquer platform. As our Senior Platform Engineer, Voice Infrastructure, you will own and evolve the systems that power how sales teams connect with customers through calling, routing, and intelligent workflows.
Voice at Conquer is more than communications infrastructure. It is foundational to how we understand customer interactions and increasingly how we deliver real-time, intelligent experiences across our platform.
This is not a traditional telecom operations or high-level architecture role. We are looking for an engineer who combines deep telephony expertise with strong software and platform engineering skills. You should be equally comfortable designing how the platform should evolve and getting into the code, FreeSWITCH, SIP routing layer, containers, and production infrastructure to build it.
Your work will directly impact call quality and reliability today while helping build the voice foundation for the next generation of Conquer 's platform.
What You Will Do
Design, build, and scale Conquer ’s telephony infrastructure and the software services that support it
Work directly within FreeSWITCH, including call logic, dialplans, ESL integrations, and complex production troubleshooting
Build and evolve OpenSIPS routing logic and signaling infrastructure
Own integrations with domestic and international SIP trunking providers
Write, review, debug, and maintain production backend and platform code
Work directly in production environments, troubleshooting complex issues across SIP signaling, RTP/media paths, carriers, networking, and application services
Improve observability across the voice stack, including SIP, RTP, and media paths
Develop and evolve call routing, dialing workflows, and real-time communication services
Build, deploy, and operate containerized voice and platform workloads using Docker and Kubernetes
Partner closely with Engineering and Product leadership to shape the longer-term architecture and technical roadmap for Conquer 's voice platform
Help ensure the voice platform can support emerging real-time intelligence, automation, and AI-driven experiences
Document systems and create tooling and runbooks that improve team understanding and operational readiness
What You Bring
5+ years of software, platform, or infrastructure engineering experience, including significant hands-on experience with production telephony systems
Deep, hands-on production experience with FreeSWITCH, including dialplans, call logic, ESL, and complex production troubleshooting
Strong hands-on experience with OpenSIPS or comparable SIP proxy technology, including personally building or modifying routing logic
Deep understanding of SIP and RTP and experience diagnosing signaling, media-path, NAT, codec, and call-quality issues using packet captures and SIP traces
Experience owning real-time communication systems in production environments
Strong software engineering skills and demonstrated experience designing, writing, reviewing, and debugging production backend or platform code
Experience with Go, Python, or another backend/systems programming language
Hands-on experience building, deploying, troubleshooting, and operating containerized production workloads using Docker and Kubernetes
Experience designing reliable, scalable systems with a focus on performance, resilience, and uptime
Strong experience with observability, monitoring, and production incident response
Ability to move comfortably between high-level architecture and hands-on implementation
Ability to communicate complex technical concepts clearly across Engineering, Product, and other teams
Nice to Have
Experience with WebRTC end-to-end, including ICE, STUN, TURN, and DTLS-SRTP
Background with browser-based softphones or CRM-embedded calling experiences
Experience building or operating low-latency, real-time media systems
Experience with streaming audio, speech-to-text, transcription, or real-time inference pipelines
Experience building infrastructure that supports AI-driven voice or agentic experiences
Experience with real-time media observability and monitoring
Experience with VoIPmonitor, Homer, or similar voice observability tooling
Experience with call recording and transcription
Exposure to telephony-related compliance considerations such as TCPA, STIR/SHAKEN, call recording laws, and consent management
What Success Looks Like
You have improved call reliability, performance, and uptime across the platform
You have closed gaps in observability and improved visibility into real-time signaling and media performance
You are contributing production code and platform improvements, not simply recommending them
Engineering and Product teams rely on you as the subject matter expert for telephony and real-time communications
You proactively identify and resolve issues before they impact customers
You help define and execute a clear, forward-looking architecture and technical strategy for Conquer 's voice platform
You have strengthened the voice foundation needed to support new real-time, intelligent, and AI-enabled product experiences
You build systems with scalability, resilience, security, and compliance in mind
