When customers do not recognize who is calling or why, important conversations are missed, customer relationships suffer, and business outcomes are harder to achieve.\nHiya helps businesses create trusted calling experiences that benefit both sides of the conversation: enterprises can reach customers with confidence, and customers can answer with confidence. Our products support branded business calling, trusted caller identity, call performance insights, customer engagement, and voice security capabilities that help businesses strengthen relationships and improve outcomes.\nThis role sits in a core business area for Hiya and is focused on helping SMB and enterprise customers succeed.\nAbout the Role\nThis role is part of a foundational team working at the intersection of backend systems, real-time voice infrastructure, and applied AI. You won't be maintaining legacy code or tweaking existing services-you'll be designing and building the backend platform from the ground up.\nWe're looking for engineers who get excited about greenfield architecture, who want to make early decisions that shape how a product scales, and who thrive when there's more whiteboard than runbook. As a Senior Backend Software Engineer, you'll design and build the backend services and APIs that power Hiya's next-generation voice products. This is a backend-first role with opportunities to work across the stack when it adds value.\nOur team builds the platform at the intersection of voice, telephony, and artificial intelligence. Our work spans both audio intelligence (e.g., deepfake detection, speaker verification) and conversational AI, focused on building resilient, scalable systems that integrate into operator networks and enable our platform to perform in real-time telephony integrations.\nWhat You'll Do\nDesign and build backend services and APIs from scratch using TypeScript / Node.js\n\nBuild real-time voice systems: SIP/RTP media handling and STT/TTS pipelines with strict latency requirements\n\nMake foundational architecture decisions that will shape the platform for years to come\n\nBuild systems that operate in real-time, high-availability voice environments\n\nWork with data stores and event streams, and manage deployments using Docker and Kubernetes (AWS)\n\nCollaborate with a distributed team (Seattle and Europe) with async-first norms\n\nThis is a hybrid role with 3 days per week in office in Seattle and some travel required on an as-needed basis\n\nWhat Success Looks Like\n4+ years of professional experience as a backend or backend-leaning full-stack engineer\n\nStrong fundamentals in backend architecture, API design, and data-driven systems\n\nExperience working with cloud infrastructure and CI/CD pipelines\n\nComfort with ambiguity-you know how to make good decisions without a playbook\n\nInterest in applied AI, voice technology, or telephony (direct experience a plus, not required)\n\nExcellent communication and self-organization skills\n\nWhat We're Looking For\nRequired:\n3+ years of professional software engineering experience\n\nStrong depth in TypeScript or Python; demonstrated ability to work meaningfully in other languages\n\nExperience with Node.js backend development and modern web service patterns (REST APIs, async processing, event-driven systems)\n\nFamiliarity with DevOps basics: containers (Docker), deployment workflows, and reading infrastructure configs (Terraform, Helm, or similar)\n\nAbility to work across Android or iOS code - you don't need to be a mobile specialist, but you can navigate a Kotlin or Swift codebase and make focused changes\n\nStrong written and verbal communication - you write clear tickets, clear PRs, and proactively flag blockers rather than going quiet\n\nPragmatic judgment - you make sensible tradeoffs between speed and perfection and can explain why\n\nAutonomous on well-scoped work - once you understand the goal, you drive to completion without needing hand-holding\n\nHonest about what you don't know - you ask good questions early rather than disappearing and surfacing problems late\n\nReliable throughput - you ship consistently and follow through on commitments\n\nActive use of AI tooling - you leverage AI-assisted coding as a force multiplier and have a point of view on where it creates real leverage in this kind of work\n\nPreferred:\nExperience with VoIP or telephony (SIP, RTP, WebRTC) or interest in learning it\n\nCarrier or B2B platform context\n\nExperience with Databricks, Kafka, or streaming data pipelines\n\nFamiliarity with AWS (DynamoDB, S3, Kinesis, EKS)\n\nHow We Work\nHiya is not a passive environment. We expect people to take ownership, form opinions, and engage directly with hard problems.\nWe 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.\nYou’ll be expected to work through ambiguity, weigh tradeoffs, and take responsibility for results-while keeping a high bar for quality and customer trust.\nEvery team member at Hiya is expected to live our core values:\nServe, our customers and partners by holding a high bar for trust and quality\n\nOwn, share in success and open up to failures\n\nLead, listen, show up with a point of view but commit entirely once a decision has been made\n\nImprove, even if it means changing course or contradicting ourselves\n\nDo, rather than observe\n\nOur Interview Process\nAt Hiya, our interview process is designed to evaluate candidates through real, experience-based work. We focus on understanding how you think, exercise judgment, use leverage (including AI), and collaborate, rather than how well you perform in traditional interviews.\nProcess Overview\nOur standard interview process follows this sequence:\nInitial Screen: We confirm baseline alignment, role interest, relevant experience, and logistics.\n\nHiring Manager (HM) Screen: We evaluate role fit, expectations, and execution readiness.\n\nOnsite Interview Loop: Each interviewer focuses on specific competencies, evaluating how you make decisions, navigate tradeoffs, and collaborate in real time\nLive Working Assignment You’ll then participate in a live, role-relevant working session as part of an interview loop with multiple interviewers. This experience is designed to reflect how work is done at Hiya and focuses on your real-time problem-solving and collaboration skills.\nDuring the session, you’ll work through a problem live and walk interviewers through your thinking as you go. Interviewers will explore how you structure problems, communicate your reasoning, respond to questions and feedback, and adapt your approach in the moment. .\n\nFuture Hiya Value Interview: An independent conversation focused on your long-term potential, judgment under ambiguity, and ability to create sustained value as scope and complexity increase.\n\nReference Check: As a final step, we connect with 2-3 past supervisors to gain additional perspective on your experience and working style, and to further understand how you align with Hiya’s values.\n\nHow We Invest in You\nCompensation & Ownership\nBase Salary: $113,000-$197,000\nCompensation is determined by role scope, skills, experience, location, and market data.\n\nEquity Compensation: ownership aligned with your impact and the company’s growth\n\nBenefits & Support\nEmployer-sponsored Insurance\nMedical, dental, and vision (PPO & HDHP); 50% dependent coverage\n\nHealth, flexible spending, and dependent care accounts\n\nLife, AD&D, and accident coverage, with company-paid life and long-term disability\n\n401(k) with 3% company match (via Fidelity)\n\nFlexible vacation policy and paid company holidays\n\nPaid parental leave\n\nWork-from-home equipment stipend\n\n$1,000 annually to invest in your learning and growth\n\n$1,000/year in charitable donation matching\n\nTeam lunch 2x per week\n\nCome Work With Us!\nWe're building a team with diverse perspectives, identities, and professional experiences. We evaluate candidates through a business lens and believe that diversity and unique viewpoints make our company stronger, more dynamic, and a great place to build a career.\nWe've been recognized by Built In, GeekWire, Comparably, G2, Forbes, and Deloitte Technology Fast 500 for our culture, innovation, leadership, compensation, and more. At Hiya, we're a people-centric company focused on helping each employee grow both personally and professionally. We create a culture of support and empowerment that challenges the status quo, resulting in an energized team that's passionate about their work.
