Hiya

Build and maintain backend services and mobile integrations for caller ID, spam detection, and AI features, ensuring high availability and low latency. | Experience with production Node.js services, AWS infrastructure, mobile app backend systems, and collaboration with mobile SDKs, with a focus on high reliability and low latency. | About Hiya At Hiya, we're making calls safe, useful, and human again. Voice is the most human form of communication, yet it's become one of the least trusted. Spam, scams, and AI manipulation have eroded what was once a simple way to connect. Each month our AI voice technology analyzes 28+ billion calls, protecting over 550 million users and 800+ businesses worldwide. Partnering with a growing global network including, AT&T, Samsung, British Telecom EE, Rogers, MasOrange,Bell Canada, MasMovil, and Virgin Media O2, we're not just stopping bad actors, we're helping people feel good and confident about picking up the phone again. This is a pivotal moment for voice. As new threats and technologies accelerate, so does demand for trusted voice communication. Hiya is growing 40%+ year over year, expanding globally, and defining what voice becomes next. Join us. You won't just work on what voice is today, you'll shape what it becomes tomorrow: smarter, safer, and genuinely worth answering again. About the Role The Mobile Experience team owns Hiya's two consumer mobile applications: Hiya AI Phone—an AI-powered phone assistant with real-time scam detection, intelligent call screening, and call transcription—and Hiya Spam Blocker—our established caller ID and spam blocking app with over 10 million downloads. Together, these products protect millions of users from fraud and unwanted calls across iOS and Android. We're looking for a Software Development Engineer to build and own the backend services and mobile integrations that power both applications. You'll work across the stack: designing Node.js services deployed on AWS, scaling infrastructure that handles millions of lookups and call events, building call screening and spam detection features, and collaborating with mobile engineers on SDK integration. The work spans real-time systems with strict latency requirements, AI-powered features that require thoughtful backend architecture, and mobile integrations that demand attention to platform-specific behavior. You'll have significant ownership over how these systems evolve—your decisions will directly shape the experience of users who rely on Hiya to know who's calling and stay safe from scams. What You'll Do Own backend services that power core features across both apps—caller ID lookups, spam/fraud detection, call screening, real-time scam alerts, call transcription, and AI-generated summaries. This includes designing service architecture, writing production code, deploying to AWS, and operating systems at scale with high availability and low latency. Build and maintain mobile integrations that connect backend services to iOS and Android applications. You'll collaborate closely with mobile engineers to ensure seamless SDK behavior across platforms, debug platform-specific issues, and ship features that work reliably for millions of users. Scale infrastructure to support growing user bases and new feature development. You'll make decisions about how to handle increasing load, optimize costs, and maintain reliability as both products evolve. Make architectural and implementation decisions that balance speed, quality, and long-term maintainability. You'll encounter ambiguous problems—how to handle edge cases in call screening logic, how to structure services for rapid iteration on AI features, how to maintain a shared backend that serves two distinct products—and you'll drive toward solutions with ownership of the outcome. Collaborate across engineering, product, and design to ship features that matter. The Mobile Experience team operates with high autonomy, which means you'll be involved in shaping what we build, not just how we build it. What Success Looks Like The backend services and mobile integrations you own are reliable, performant, and support the rapid iteration the team needs to improve both Hiya AI Phone and Hiya Spam Blocker. Users experience accurate caller ID, effective spam blocking, and responsive AI features—and those outcomes trace back to work you shipped. You've built enough context across the stack—services, infrastructure, mobile integration points—that you can independently identify problems, propose solutions, and drive them to completion without requiring constant direction. Your work compounds over time: services are easier to extend, infrastructure scales more efficiently, and the team ships faster because of foundations you've put in place. What We're Looking For Required: Experience shipping Node.js services in production environments Strong knowledge of AWS infrastructure and services (deployment, scaling, monitoring) Experience building backend systems that serve mobile applications Familiarity with iOS and/or Android development—enough to collaborate effectively on SDK integration and debug platform-specific issues Ability to design and operate services with high availability and low latency requirements Clear communication and the ability to work effectively with distributed teams (Seattle and London) Familiarity with AI-assisted development techniques and workflows Nice to Have: Experience with telephony, VoIP, or voice-related systems (SIP, SS7, or similar protocols) Familiarity with AI-assisted development techniques and workflows How We Work Hiya is not a passive environment. We expect people to take ownership, form opinions, and engage directly with hard problems. We work with a high degree of transparency and autonomy. Context is shared openly, and decisions are discussed, challenged, and then made. Once a call is made, we commit and move forward. You’ll be expected to work through ambiguity, weigh tradeoffs, and take responsibility for results, while keeping a high bar for quality and customer trust. Every team member at Hiya is expected to live our core values: Serve, our customers and partners by holding a high bar for trust and quality Own, share in success and open up to failures Lead, listen, show up with a point of view but commit entirely once a decision has been made Improve, even if it means changing course or contradicting ourselves Do, rather than observe Our Interview Process Process Overview Our standard interview process follows this sequence: Initial Screen: We confirm baseline alignment, role interest, relevant experience, and logistics. Hiring Manager (HM) Screen: We evaluate role fit, expectations, and execution readiness. Take Home Assignment: You'll complete a take-home, role-relevant assignment designed to reflect the kind of work you would do at Hiya.
