About AiMAWe develop technology that complements human care and helps provide continuity when another person is not available.

About the role
We are looking for aJunior R&D; Software Developerto help turn technical ideas into working prototypes, measurable experiments and reliable integrations.
You will work withAI models, voice technologies, computer vision and physical devices, exploring how software performs under real-world conditions.
Which voice synthesis solution offers the best balance of quality and latency? Can a tablet run a particular AI model locally with acceptable performance?

Key responsibilities
Build prototypes and integrationsTurn research ideas and technical hypotheses into functional software prototypes.
Connect software with tablets, microphones, speakers, cameras and other peripherals or sensors.
Design and run technical experimentsBuild repeatable evaluations to compare models, providers, architectures and device configurations.
Define and measure relevant metrics, including quality, latency, reliability and resource consumption.
Test systems under realistic conditions, such as background noise, unstable connectivity and extended operation.
Document the hardware, software versions and configuration needed to reproduce results.
Investigate software and device issuesUse logs, traces, profiling tools and experimental data to investigate unexpected behaviour.system configuration or hardware.
Investigate audio and video capture, permissions,



device compatibility and performance bottlenecks.
Collaborate and share findingsWork closely with the technical lead and R&D; engineers.
Turn successful experiments into reusable scripts, services and test suites.
Essential requirementsSolid programming skills in at least one relevant language, such asPython, TypeScript/JavaScript or Dart . Experience building working software through academic projects, personal projects, internships or employment.
Practical experience connecting software to a physical device or peripheral, such as a tablet, microphone, camera, sensor, Raspberry Pi or microcontroller.
A basic understanding of how processor capabilities, RAM, connectivity and thermal limitations can affect software performance.
Hardware experience does not need to come from a professional role: a relevant university or personal project is equally welcome.
Flutter/Dart, particularly native integrations, audio capture or streaming.
Backend or cloud technologies such as Firebase, Firestore, Cloud Functions or Cloud Run.
Experience with Android development tools, ADB, Linux or device profiling.
Exposure to audio concepts such as echo cancellation, sample rates, microphone selection or background?Basic software testing, observability and performance measurement.
You should be comfortable moving between code and a physical setup: connecting a device, checking its configuration, running an experiment and explaining the results.from 28K to 34K before taxes. #
