Senior Software Engineer in Test

At Replicant, we believe AI should work for people, starting with customer service. We’re looking for a Software Development Engineer in Test (SDET) to help raise the bar for quality across our voice AI platform as we continue to scale. This person will play a key role in shaping how quality is defined, measured, and built into the product experience from the start — across platform capabilities, AI agents, customer configurations, integrations, and release workflows. This is an opportunity to help build the systems, standards, and tooling that make quality a durable advantage for both our customers and our teams. As a SDET you will partner closely with Engineering, Product, and Delivery to create a more unified and scalable approach to quality. You’ll define standards, improve testing strategy, build and evolve automation and platform-level tooling, and turn customer and product insights into better validation systems. This is a hands-on engineering role for someone who is excited to work at the intersection of software quality, automation, analytics, and AI. The right person will help us move toward a modern quality engineering practice where testing is proactive, automated wherever possible, and grounded in the realities of conversational AI. What You'll Do - Act as a senior technical authority for quality engineering at Replicant; shaping how quality is built into the platform through hands-on engineering, championing a high bar across teams, and driving the practices and execution that make it real. - Raise the technical bar across our team of AI-enabled QA Engineers through hands-on example, code and test review, pairing, and mentorship; leveling up how a small team builds a scalable quality engineering practice. - Help drive Replicant's AI-native quality engineering strategy to scale coverage, accelerate validation, and surface failures earlier. - Build AI-driven testing workflows that let a small team deliver broad, scalable validation across the platform. - Own the quality feedback loop from internal dogfooding, customer A/B testing, customer feedback triage, and bug reporting, turning real-world usage into faster fixes, better test coverage, and stronger product decisions. - Partner with Product and Engineering early to improve testability, shape acceptance criteria, and build quality in from the start. - Build and improve automation frameworks, validation tooling, and CI/CD quality gates for reliable, repeatable releases. - Use AI and analytics to expand edge-case coverage, summarize failures, and generate insights that inform roadmap and release decisions. What You'll Bring - 5+ years in SDET or quality engineering roles, with significant hands-on coding, including ownership of test strategy and release quality in complex software systems. - Strong programming skills in at least one modern language (TypeScript, JavaScript, or Python), with the ability to build and own production-quality tooling and frameworks. - An AI-native approach to quality engineering. You know how to leverage AI to move faster, increase coverage, reduce manual effort, and build smarter testing and validation workflows. - Curiosity about AI systems, conversational experiences, and the nuances of testing voice-driven product behavior. - Experience building quality initiatives across teams and influencing engineers, product managers, and stakeholders around a shared quality bar. - Deep knowledge of modern testing practices, including automation, API and integration testing, regression strategy, and CI/CD-based quality workflows. - Demonstrated mastery of test design, risk-based coverage, and what should be automated versus explored manually. - Comfort using data, metrics, and analytics to evaluate quality and communicate trends, risk, and opportunities for improvement. - Excellent collaboration and communication skills, with the ability to work effectively across Engineering, Product, and customer-facing teams. Nice To Have - Experience testing AI and LLM-powered systems, including evaluating non-deterministic behavior, hallucinations, prompt or workflow regressions, and other quality issues unique to generative products. - Experience working in an FDE, delivery, or professional services environment, with a strong understanding of customer-facing implementation workflows and real-world quality challenges.

It is critical that everyone who joins the team feels excited and moved by these values as every new team member makes an impact on our culture. Blade Runners: We take ownership and pride to influence the outcomes of our goals. We are successful, and like a Blade Runner, use the tools at our disposal to reach our objectives. We value open and honest communication and proactively seek feedback along the way. We are a company driven to grow and achieve both individually and as a team. Bread Makers: We are humble and strive toward an egalitarian culture. No task is too big or too small. We work together to achieve our goals and develop our company mission. We believe that the whole is greater than the sum of its parts in everything that we do. Självdistans (Self-Distance): Självdistans is Swedish for self-distance. It's the ability to critically reflect on oneself and one's relations from an external perspective. With this in mind, we act with objectivity and always remember that we are not our work. There's no perfect science to growing a team or business, but we trust everyone at Replicant to point out our blind spots and humbly admit their own.
