At dot. we’re developing next-generation smart detection products that use advanced sensors, machine learning, and odour biomarkers to identify pests, pathogens, and other biological threats in real time. Our first smart product is nearing launch, with a broader platform vision across agriculture, animal health, and human diagnostics.

As we scale, we’re looking for a hands-on Data Scientist to help turn our sensor data into powerful machine learning models that run on embedded devices.

The Role

Reporting to the Lead Data Scientist, you’ll be responsible for the development and deployment of machine learning models that sit at the heart of our detection platform. Working closely with the R&D, product engineering, data engineering and firmware teams, you’ll help transform sensor and VOC (volatile organic compound) data into robust, real-time classification tools — from lab to live field deployment.

This role bridges data science, embedded ML, and applied product development. You’ll be working with real sensors, real-world constraints, and real devices — not just simulation or dashboarding.

Key Responsibilities

Clean, structure, and analyse odour/sensor datasets for training and evaluation.
Develop and optimise lightweight ML models (e.g. TensorFlow Lite) for embedded deployment.
Collaborate with firmware engineers to integrate models into our smart trap prototypes (via platforms like Edge Impulse or custom firmware).
Test model performance across lab, semi-field, and real-world settings; tune for reliability and accuracy.
Maintain and document training pipelines, feature engineering methods, and model validation results.
Support future product rollouts by adapting the detection model for different species, applications, and use environments.
Assist in developing model-driven features for the platform (e.g. confidence scoring, anomaly detection, retraining logic).

What You Bring

Must-haves:

5+ years of experience in applied data science or ML engineering roles.
Strong applied experience in machine learning (ideally classification-focused).
Proficiency in Python and relevant libraries (scikit-learn, TensorFlow, pandas, etc.).
Experience working with real-world sensor or time-series data.
Familiarity with embedded ML tools (e.g. TensorFlow Lite, Edge Impulse) or willingness to learn.
Hands-on mindset — comfortable working in close collaboration with hardware, firmware, and product teams.
Clear communicator who can explain model behaviour and constraints to non-technical collaborators.

Nice-to-haves:

Experience in signal processing, low-power sensing, or IoT.
Previous work on edge-deployable models.
Interest or background in biology, chemistry, or environmental sensing.
Familiarity with HDF5, metadata tagging, or sensor calibration pipelines.
Experience in versioning datasets and ML workflows (e.g. MLFlow, DVC).

What Success Looks Like

Within your first 12 months, success in this role means:

Models in the field, not just the lab. You've taken at least one detection model from training through to embedded deployment on a live device — validated across lab, semi-field, and real-world conditions — with documented accuracy and reliability benchmarks that the product and R&D teams trust.
A repeatable ML pipeline that others can build on. Training, feature engineering, validation, and versioning are no longer ad hoc processes. Working in collaboration with the Lead Data Scientist, you've established clean, documented workflows that mean the team isn't starting from scratch each time a new dataset, species, or use case arrives.
The platform thesis is technically credible. You're actively contributing to dot.'s cross-domain ambitions — helping demonstrate that models and data structures built for one application (e.g. bed bug detection) can be adapted and transferred to others, supporting the Level 2 and Level 3 data value story we're building toward Series A.
Firmware and hardware teams see you as a genuine collaborator. You're the bridge between data science and embedded systems — fluent enough in the constraints of the device environment that integration doesn't become a bottleneck, and trusted by engineers as someone who understands the real-world limits of what a model needs to do.
dot.core has a stronger data foundation. Your work on sensor datasets - cleaning, structuring, metadata tagging, calibration pipelines - means dot.'s core data asset is more valuable, better labelled, and increasingly defensible as a proprietary dataset, not just a byproduct of discovery projects.

Why Join Us?

Be part of a fast-growing, mission-driven company working at the intersection of science and technology.
Your work will live in physical products that create measurable impact across public health, agriculture, and more.
Collaborate with a multidisciplinary team of scientists, engineers, and domain experts.
Work in an environment that values autonomy, innovation, and meaningful problem-solving.

Pay: £50,000.00-£60,000.00 per year
