We’re looking for talented
Senior Full Stack Software Engineers to join one of our three high impact teams:
Runtime,
Data, and
Product Engineering. All three teams work closely together, share high engineering standards, and solve challenging technical problems at scale, but each has its own mission and area of focus.
- Runtime: own the global infrastructure that powers real-time voice interactions. In this role, you’ll work at the core of the agentic process - streaming audio, transcribing speech, using LLMs and acting on their output, and synthesising natural voice. You’ll design and optimise systems across VoIP, WebRTC to deliver low-latency, secure, and reliable conversations. Your work directly shapes the user experience of every call, driving down response times, improving comprehension, and ensuring we meet strict SLAs for performance and security.
- Data: play a key role in delivering the next generation of our no-code agent studio platform. In this role, you’ll be leading the design and development of features that power insight generation, reporting, and the data-driven backbone of our no-code platform for building voice assistants.
- Product Engineering: help shape our cutting-edge low-code platform. This role offers the opportunity to work end-to-end, from design to implementation, on creating features which enable a simple user experience for interacting with complex AI systems.
You’ll go through a
centralised hiring process that lets us get to know your skills and preferences, while you explore which team best aligns with your interests and expertise. At the end, we’ll match you with the team where you can have the most impact.
Depending On Team, Responsibilities Can Include
- Contributing to our user-facing platform for building and configuring voice assistants,
- Contributing to the implementation of our multi-tenant infrastructure, across multiple cloud vendors ensuring long-term scalability and maintainability.
- Taking a major role in our software development, through writing code, tests, as well as contributing to design ideas, documents and performing code reviews.
- Working independently on the technical design and implementation of full stack features for our agent studio platform, from UI through backend to data pipelines
Requirements
- 3+ years as a professional Software Engineer, with significant experience delivering both backend and frontend features in production.
- Proficiency in Python and React
- Hands-on experience in designing, deploying, and maintaining RESTful APIs
- Experience with one or more cloud services: AWS, GCP, Azure
- Understanding of algorithms, data structures, system design and complexity analysis
We currently have multiple engineering roles open across different teams.
Please apply to the one role that feels like the best match for your skills and experience. Our Talent team will review your application against
all open positions. If we believe you may be a stronger fit for another role or team, we’ll ensure your application is considered there as well.
