Are you a software engineer with a strong data science and data engineering background, passionate about building systems that turn large-scale data into reliable products? Do you enjoy owning the full lifecycle — from pipeline architecture to the models and metrics running on top of it — and mentoring others along the way? If so, we invite you to join Nexthink as a Senior Software Engineer, Data Science on our Cloud Intelligence team!
As a key member of Cloud Intelligence, you will design and ship the data products, pipelines, and services that power our data lake, experimentation, and analytics capabilities — helping shape the digital employee experience for millions of users worldwide. This is an engineering-led role: you'll bring strong software engineering judgment first, paired with the data science skills to know what's worth building.
Responsibilities
-
Design & Ship Data Products – Architect, build, and ship reliable, well-documented data products and services (from pipelines to APIs) that internal teams and external customers can depend on.
-
Data Lake Infrastructure – Build, scale, and maintain the data lake and its underlying pipelines (e.g., using Spark), ensuring data is reliably ingested, processed, and structured for both analytical and production use.
-
Applied Data Science – Explore large-scale datasets to uncover patterns, quantify product impact, and inform the design of the systems and metrics your team builds.
-
AI/ML Leverage – Leverage AI to enhance the development process and the quality of the software and data products your team delivers.
-
Collaboration & Leadership – Work closely with data engineers, ML engineers, and product teams to align data capabilities with business needs across the stack.
-
Mentorship & Coaching – Guide and support junior engineers and data scientists, fostering a culture of learning and knowledge sharing.
Qualifications
-
BSc/Master's degree (or PhD) in Computer Science, Data Science, Machine Learning, Statistics, or a related field.
-
5+ years of hands-on experience as a software engineer working on data-intensive systems, ideally with direct data science or applied ML exposure.
-
Strong software engineering fundamentals — clean architecture, testing, CI/CD — applied to data and ML workflows.
-
Hands-on experience with distributed data processing frameworks (e.g., Spark) and building/maintaining data lake infrastructure at scale.
-
Proven experience with cloud-based data platforms (AWS preferred).
-
Strong proficiency in Python and standard data tooling (e.g., pandas, NumPy, scikit-learn, SQL).
-
Solid data intuition: ability to inspect raw logs, design metrics, and quickly identify quality regressions.
-
Working knowledge of experimental design, statistical inference, and A/B testing methodology.
-
Excellent problem-solving skills and ability to work in a fast-paced, collaborative environment.
-
Strong communication skills in English, capable of explaining complex technical concepts to both technical and non-technical stakeholders.
-
Eagerness to learn and adapt.
If you're excited about designing and shipping data products at scale, and mentoring the next generation of engineers and data scientists, we'd love to hear from you! Even if you don't meet every requirement, we encourage you to apply — we value expertise, passion, and the drive to learn.
