Overview

Sensoteq, based in Belfast, Northern Ireland, United Kingdom — Senior Software Engineer

At Sensoteq, based in Belfast, we are on a mission to transform how industries keep their machines running. By combining cutting-edge sensors with powerful software, we are creating the next generation of condition monitoring tools, helping our customers predict faults, cut downtime, and boost efficiency.

You will be joining a small, agile, and driven team focused on impact. Every project matters, every line of code counts, and every idea has the potential to shape the future of our product.

Reporting directly to our Software Manager, you\'ll play a hands-on role in designing and delivering real products that solve real problems. We\'re looking for experienced professionals with a proven track record of building and shipping software who thrive in collaborative, cross-disciplinary environments and enjoy tackling complexity and ambiguity head-on. If you\'re excited by the idea of joining a team where your work makes a visible impact, and where innovation moves quickly, you\'ll fit right in at Sensoteq!

Responsibilities

• Work with the product team to define problems clearly and make success measurable.
• Rapidly prototype, validate with users, and ship – keeping feedback tight and progress aligned.
• Design and implement scalable serverless infrastructure using AWS tools like Lambda, SQS, SNS, SES, and ECS - with infrastructure-as-code managed through SST.
• Use modern AI-native tools (e.g. Cursor, Bolt, Lovable, Windsurf etc) to speed up development, design smarter UX, and ship better product experiences faster.
• Track success using product analytics tools like PostHog to validate what\'s working - and improve what isn\'t.
• Write clear, purposeful documentation that spreads product knowledge, shortens onboarding, and helps teammates get up to speed fast.
• Contribute to team growth through reviews, pairing, shared tools, and consistent feedback.
• Collaborate with the data team to integrate ML models or surface insights through the application where needed.

What You Will Need

• 6+ years of relevant software engineering experience.
• Proven ability to take ownership by identifying and resolving underlying challenges, ensuring lasting solutions rather than simply completing tasks.
• Full-stack experience: You’ve built and shipped web applications across our stack and can adapt quickly to new tools as needed.
• Product collaboration: You’re comfortable engaging early - ensuring the problem is clear, measurable, and grounded in reality.
• AI leverage: You look for pragmatic ways generative AI can give us an edge - in product or in development.
• Analytics-informed: You value product analytics and know how to use tools like PostHog to validate what works.
• Ability to adapt quickly and help others do the same.
• Experience working independently with sound judgement, but can bring in others at key moments to keep work visible and aligned.
• Degree-level qualification in software, engineering, or similar
• No Certificate of Sponsorship (CoS) will be provided for this position

Nice To Have

• Experience with Python or machine learning, especially where it supports integration with data science workflows.
