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 Us\nAt Hiya, we're making calls safe, useful, and human again.\nVoice 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. Hiya is changing that.\nEach 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.\nThis 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.\nJoin 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.\nAbout the Role\nHiya is hiring a Senior Software Engineer to join the Protect team, responsible for building and scaling the AI-powered spam and scam detection systems that protect hundreds of millions of people from fraudulent calls before they ring. As voice threats evolve faster than ever; driven by AI-generated abuse, sophisticated spoofing, and increasingly complex attack patterns. You'll own the end-to-end pipeline that enables our data science team to develop increasingly sophisticated scam detection models while maintaining strict privacy and regulatory compliance. It's all about building the pipelines that allow Hiya to stay ahead of rapidly evolving voice threats and deliver measurably better protection to mobile operators and their subscribers worldwide. You'll shape how protection scales across our network, how quickly we adapt to new threats, and how effectively we translate AI innovation into real-world safety outcomes.\nWhat You'll Do\nOwn the complete development lifecycle for spam and scam detection infrastructure - from researching and proposing solutions to implementation, testing, deployment, production maintenance, and monitoring\n\nParticipate in on-call rotation, ensuring rapid recognition and resolution of production issues while continuously improving system reliability\n\nDesign and build frameworks that enable data scientists to develop, test, and deploy increasingly complex scam detection models with access to call data in a privacy-aware, regulation-compliant manner\n\nMake independent implementation decisions while driving collaborative design discussions that improve system quality, long-term maintainability, and cost-effectiveness across the team\n\nEvaluate critical tradeoffs between immediate fixes and durable solutions when production issues arise, prioritizing overall service quality and system resilience\n\nCollaborate proactively with cross-functional partners - including product managers, data scientists, and other engineering teams - to align technical decisions with business impact, user needs, and Hiya's broader strategic priorities\n\nRecognize and evangelize engineering patterns, design principles and architectural decisions that could be adopted across teams to raise overall quality and execution speed\n\nInfluence how the team operates by pushing back on solutions that don't align with design principles, surfacing issues early during project planning, and reasoning clearly about business impact versus cost\n\nWhat We’re Looking For\nRequired\n4+ years of software engineering experience, with strong expertise in distributed systems, microservices, network architecture, and database systems\n\nProven experience operating distributed systems in production environments\n\nAbility to quickly recognize, diagnose and resolve production issues\n\nRelevant technical experience may include:\nRxM engineering\n\nTCP/IP\n\nDNS resolution\n\nWeb backend development\n\nAbility to evaluate tradeoffs between immediate fixes and long-term solutions\n\nStrong focus on service quality, reliability and system resilience\n\nAbility to work independently on implementation while knowing when to involve others in design discussions\n\nConfidence making well-informed technical decisions and clearly explaining tradeoffs\n\nInterest in agentic workflows, including engineering automation and customer-facing applications\n\nPreferred\n6+ years of software engineering experience\n\nExperience building frameworks or infrastructure that support data science or machine learning workflows\n\nFunctional programming experience\n\nExperience with data processing pipelines, especially Kafka or similar technologies\n\nFamiliarity with client-side processing pipelines\n\nDevOps, monitoring, and observability experience\n\nFamiliarity with on-call rotation\n\nThe person in this role must embody Hiya’s key values of Serving our customers, Doing rather than observing, Improving ourselves and our business, Owning and holding ourselves accountable for success, and Leading by showing up with a point of view, engaging in open discussion, listening respectfully to others opinions and committing to decisions.\nThe requirements listed in the job descriptions are guidelines.

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\nTake Home Working Assignment: You'll complete a take-home, role-relevant assignment designed to reflect the kind of work you would do at Hiya. The assignment focuses on how you think, prioritize, and explain your approach. You'll review your work and discuss your reasoning with the interview panel\n\nOnsite Interview Loop: You’ll 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. During the session, you’ll work through your take-home assignment 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. Part of this loop also includes our Hiya Future Values 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.\nBenefits\nStock options\n\nPrivate Retirement/Pension program through Erste Bank\n\nGenerali Private Health Care\n\nDonation Matching for a charity of your choice (up to $500/ year)\n\nWFH equipment stipend (up to $500 in your first year)\n\n$1,000/year in Professional Development funds\n\nOnline English Classes\n\nGym membership\n\nFlexible working model (2 days a week, Tuesdays and Thursday is required in the office.
