The posting

About Ajentik

Ajentik AI Pte. Ltd. is a Singapore healthtech company incubated at NUSX (formerly NUS Enterprise). We build Elderwise, an AI-powered Comprehensive Geriatric Assessment (CGA) platform that turns caregiver observations into structured, EMR-ready clinical summaries. Caregivers speak with our voice assistant in the browser, with no app to install. Clinicians receive a structured summary to review and file, and families receive a plain-language report. We are in pilot discussions with geriatric teams across Singapore's public healthcare clusters and the community care sector.

About the Role

As an AI Engineer, you will build the conversational and extraction pipelines at the heart of Elderwise: the voice conversation with a caregiver, the structured clinical fields it produces, and the summary a clinician reviews and signs. You will ship to real users in a setting where accuracy, privacy and clinician trust matter more than demo polish.

The role suits an engineer with one to four years of experience who has shipped software to production and wants to go deep on applied LLM engineering. You will work directly with the founders, our engineers and our Clinical Lead, with experienced engineers reviewing your designs and code. Your scope will grow as you show you can own it.

Key Responsibilities

  • Build and improve LLM pipelines end to end: conversation design, prompting, structured outputs, schema validation, retries, logging and storage
  • Turn caregiver conversations into validated clinical fields, each traceable to what was said and marked as stated, inferred or not asked
  • Integrate speech-to-text and text-to-speech into low-latency voice conversations, and catch transcription errors before they reach a clinical document
  • Grow our evaluation suite: golden sets, synthetic caregiver personas, adversarial cases and regression checks that run in CI on every prompt or model change
  • Track quality, cost and latency per release, and make model and prompt changes on evidence rather than intuition
  • Push the boundaries of what our AI can do: prototype next-level capabilities such as emotion and stress detection from voice and conversation, measure them rigorously with our Clinical Lead, and take what works from experiment into the product
  • Build guardrails that hold every time: no diagnosis or medical advice, safe escalation paths and defences against prompt injection
  • Produce interoperable outputs (structured JSON, PDF reports and HL7 FHIR R4 resources) that fit how hospitals file records
  • Handle personal and health data responsibly under PDPA and our ISO 27001 and ISO 42001 programmes, from data minimisation to redacted logs
  • Work spec-first with AI coding agents: write the spec and tests, let the agent implement, and own the result
  • Join clinician and caregiver sessions to see how the product is used, and turn what you learn into engineering work

Requirements

  • 1 to 4 years of professional software engineering experience, with strong Python
  • At least one LLM-powered feature or product you built that real users relied on, not only a demo, and the ability to explain what broke and how you fixed it
  • Working knowledge of structured outputs, prompt design and the ways LLMs fail, including hallucination, non-determinism and behaviour changes between model versions
  • A habit of measuring: you write tests and evaluations, not only prompts
  • Solid fundamentals in APIs, SQL, Git, automated testing and CI
  • Clear written communication in English, and honesty about what you know and what you don't
  • Care for privacy and safety when working with sensitive personal data

Nice to Have

  • Experience with voice or speech systems: streaming STT and TTS, turn-taking and realtime audio
  • FastAPI and Pydantic, PostgreSQL with pgvector, Supabase, Docker and Kubernetes
  • Retrieval (hybrid search, reranking) and agent tool use, including the Model Context Protocol (MCP)
  • Serving open-weight models (for example with vLLM) or running small models on device
  • Research or prototyping in affective computing, speech emotion recognition or multimodal models
  • Healthcare data standards such as HL7 FHIR, or experience in healthtech or another regulated domain
  • Conversational Mandarin, Malay or Tamil, to help evaluate multilingual caregiver conversations
  • A degree in computer science, engineering or a related field, or equivalent practical experience

What We Offer

  • Competitive salary with equity participation
  • Real ownership of production AI systems from your first month
  • Room to explore new AI capabilities and take the best ideas into production
  • Mentorship from experienced engineers, our Clinical Lead and the founders
  • Direct contact with the clinicians and caregivers who use what you build
  • Access to frontier and open-weight models and modern AI development tooling
  • Health benefits and flexible work arrangements
  • Learning budget for courses and conferences
  • A clear path toward Senior AI Engineer as the engineering team grows

Your Impact

Every field our pipeline captures correctly is one less question a clinician has to ask again, and every hour we save goes back to patient care. Your work will decide whether clinicians can trust AI with the information that shapes care for older adults, in Singapore and beyond.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
