Description

THE COMPANY BEHIND THE PRODUCTS Every business talks about “better customer conversations.” SaaS Labs builds products that actually make them happen. What are we building? Through a powerful ecosystem including JustCall [https://justcall.io/], CallPage, and ServiceAgent.ai, we empower thousands of businesses to move beyond talk and drive truly meaningful customer conversations. Where are we now? Supported by a community of over 6,000 customers, a dedicated team of 300+ across India, Poland and the US, and the strategic backing of Peak XV and Base10 Partners, we are fundamentally redefining the art of customer conversation - and we're just getting started. What's it like to work here? Total ownership. We’re a team that moves with purpose, builds with ambition, and loves seeing our work make a real impact. And, if you're already nodding along, let's start the conversation. OUR FLAGSHIP PRODUCT With JustCall [https://justcall.io/], we’re leading the innovation on how sales and service teams connect with their customers using AI across calls, texts, emails, WhatsApp, and whatever comes next! It’s a multichannel communication system that helps 7000+ of our customers serve theirs better- with 24/7 AI Agents, on-point integrations, and other forward-looking features. YOUR MISSION We’re hiring a Head of Engineering, AI to lead the next generation of AI-native communication products at JustCall. This is a deeply hands-on leadership role where you’ll own engineering across our AI initiatives especially our AI Voice Agent platform (AIVA). You’ll work closely with Product, Design, and AI leadership to shape the technical direction behind fast, reliable, and production-grade AI experiences. We’re looking for a strong builder and technical leader who can architect systems, raise the engineering bar, mentor teams, and stay close to the code, infrastructure, evals, latency, reliability, and production debugging that power modern AI systems. * Lead engineering across AI Voice Agents (AIVA), AI Coaching, Conversation Intelligence, AI Workflows, and future AI-native products. * Stay deeply hands-on with architecture, coding, debugging, latency optimization, observability, and production reliability. * Build scalable voice AI systems across orchestration, real-time infrastructure, memory/context handling, evals, and workflow execution. * Define AI quality frameworks including golden datasets, eval pipelines, regression detection, scoring systems, and operational metrics. * Drive technical decisions across model selection, prompting, fine-tuning, RAG, infrastructure, and platform architecture. * Hire, mentor, and grow a high-performing AI engineering organization while maintaining a strong technical culture. * Partner closely with Product and Design to deliver AI experiences that feel intuitive, reliable, and production-ready. * Help shape JustCall’s long-term AI roadmap across multilingual support, outbound AI agents, vertical workflows, and omnichannel automation. YOUR TOOLKIT * 8+ years of experience building distributed systems, AI/ML products, real-time systems, or voice infrastructure, with 3+ years leading engineering teams. * Strong track record of shipping production-grade AI products used by real customers at scale. * Experience building agentic systems with orchestration, tool calling, retries, fallbacks, memory/context management, and graceful degradation. * Deep hands-on expertise with eval systems, automated testing, regression detection, and operational monitoring for LLM applications. * Strong systems thinking around latency, reliability, observability, and production debugging in AI environments. * A player-coach mindset with the ability to lead teams while remaining highly technical and execution-oriented. * Strong product intuition and engineering judgment with the ability to balance experimentation, speed, and scalability. EXTRAS THAT GIVE YOU AN EDGE * Experience building or scaling production voice agents using platforms such as Pipecat, Retell, Vapi, LiveKit, ElevenLabs, or similar infrastructure. * Familiarity with the hard problems in voice AI: interruption handling, semantic turn detection, latency optimization, accented speech recognition, multilingual conversations, and real-time orchestration. * Experience making architectural decisions around prompting, fine-tuning, RAG, memory systems, and model routing. * Experience hiring and scaling high-performing engineering teams in India. BENEFITS * Take time off when you need it. We trust you to manage your energy and schedule responsibly. * We don’t track hours, just impact. Work when you’re most productive, as long as you show up for your team. * Hybrid working model with 4 in-office days per week * Competitive pay that reflects your skills, experience, and the value you bring. * Once a year, we also trade Zoom calls for real hugs and high-fives, gathering somewhere nice and sunny to connect, recharge, and celebrate. * Comprehensive physical and mental health coverage for you, your partner, and your family, because care shouldn’t come with fine print. SaaS Labs takes pride in being an equal opportunity employer. We believe diverse teams build better products, which is why we're committed to taking hiring or any employment decision regardless of race, color, religion, national origin, age, sex, marital status, ancestry, disability, genetic information, veteran status, gender identity, sexual orientation, or any other characteristic.
