About the Role

You will own a voicebot end to end from scope handover to go-live including its estimate, its schedule and the customer conversation that goes with it. This is a hands-on engineering role embedded in customer delivery, not a coordination role.

What You'll Do

Customer Engagement and Solution Delivery

- Own the build of a complete voicebot, including the estimate and the delivery schedule.
- Run requirement and design sessions with customers and translate what you hear into a workable solution.
- Present pilot results, handle technical objections and drive user acceptance testing through to go-live.

Conversation and LLM Engineering
- Design the prompt architecture for a bot: persona, guardrails, escalation paths, language switching and failure behaviour.
- Work with retrieval over customer knowledge bases and tune for accuracy and latency.
- Improve bot quality through prompt optimisation and evaluation against defined test sets.

Integrations and Engineering
- Build non-standard integrations independently across whatever the customer runs — ticketing, CRM, marketing automation, deflection and contact centre systems — using REST APIs, webhooks and token-based authentication.
- Debug across telephony,



speech recognition and synthesis, and the customer's own stack.
- Build reusable components rather than repeating the same work across customers.

Product Input
- Propose product improvements with a case attached — how many customers are affected and what it unblocks.

What We're Looking For

Experience

- 2.5 to 5 years in a delivery, solutions or forward-deployed engineering role.
- Demonstrated ownership of a customer-facing technical project from start to finish.

Technical Expertise
- Hands-on coding in Python and/or JavaScript or TypeScript.
- Practical experience building on LLMs: prompt engineering, retrieval-augmented generation, evaluation or guardrails.
- Hands-on with REST APIs, webhooks and API authentication, and comfortable integrating with any customer communication stack — ticketing, CRM, marketing automation, deflection and similar systems.
- Working understanding of voice technologies — IVR, SIP or VoIP, speech recognition and speech synthesis.

Customer and Communication Skills
- Confident presenting to customers and defending a technical design.
- Able to hold scope in a customer conversation and escalate commercial questions rather than absorb them.
- Explicit written communication and disciplined follow-through.

Education

- Bachelor's or Master's in Computer Engineering, Computer Science or an equivalent computer-related degree.

Good to Have

- Experience with LLM application or agent frameworks.
- Contact centre or customer engagement platforms.
- Cloud platform experience across AWS, GCP or Azure.
- Speech recognition or synthesis tuning.
