Who We Are, What We Do
Sensat is a geospatial AI business that powers advanced and highly functional digital twins for the world's most critical infrastructure projects. We partner with the world's largest construction, engineering and critical infrastructure companies, including National Grid, Network Rail, Heathrow and Severn Trent Water. We enable our customers to fight the costly and high-risk "Status Quo" of siloed data, people and processes. Our AI-powered digital twins help teams digitally visualise, plan and manage projects, providing Project Confidence Through Clarity.
We are a high trust, high impact team, who offer purpose driven work. We operate with autonomy and flexibility in an agile, flat structure. We look for highly talented, adaptable and curious individuals who love solving meaningful problems and who share our resilient team spirit when facing challenges!
We are on track to more than double ARR in 2025, with a strong pipeline that positions us for another year of 100%+ ARR growth in 2026. Backed by over £25 million in funding from blue-chip investors like National Grid Partners and with imminent US market entry representing a significant value inflection point, this is an exciting time to join the Sensat team!
The role - why it exists & why it’s interesting
Robust infrastructure is the backbone of our digital twin platform, supporting the weight of vast, messy, multi-format project information and ensuring it is delivered with speed and absolute reliability. You’ll be part of a team of innovators helping organisations see risks earlier, coordinate better, and make decisions with confidence.
We’re looking for someone to contribute to and help shape the infrastructure of Sensat’s technology offerings — balancing competing priorities against cost efficiency, reliability and security.
This is a high-trust, high-impact role. Sensat engineers solve problems rather than solely implement solutions. You’ll contribute to, maintain and influence the architecture of our cloud services to ensure our customers have a well rounded experience, and help the team continuously raise the bar.
If you’re after autonomy, developing novel solutions, and delivering real-world value, you’ll thrive here.
What You’ll Do
Design and maintain cloud infrastructure to support reliable service deployment and scaling across multiple environments.
Development of security controls and policies, including IAM configuration, network security, and compliance monitoring.
Work to implement and improve monitoring, alerting, and incident response capabilities.
Contribute to infrastructure design decisions, focusing on reliability, security, and cost efficiency.
Contribute to and improve the standards for software engineering, such as code quality, automated testing, documentation / knowledge sharing, and broader team processes.
What You'll Bring
Strong expertise with AWS or equivalent public cloud offerings including:
ECS/Fargate or equivalent for container orchestration
VPC networking and security groups
IAM and secrets management
CloudWatch or equivalent for monitoring and alerting
Security best practises for cloud infrastructure
Experience with Infrastructure as Code tools (Pulumi preferred, or Terraform/CloudFormation)
Proficiency in TypeScript, Go or similar for infrastructure code
Experience with Docker and containerisation
3-5 years commercial experience in platform engineering, DevOps, or SRE roles.
Bonus Points For
Side-projects or participation in open source projects in a related field.
Prior work in geospatial, web mapping or construction industries.
Hands-on experience with GRPC and Protocol Buffers.
Experience in setting up and maintaining observability
Experience with implementing data pipeline, warehousing and analytics tooling
What we’ll bring:
Take a break using your 30 days of annual leave (in addition to bank holidays)
A flexible working environment
Continue learning every day through your £500 personal development fund
Regular social events! We’ve been to the theatre, racing around the tracks go-karting, had movie nights, watched the London Symphony Orchestra, line dancing lessons and murder mystery...
We’ve got your back, be it immediate access to mental health support through Spill or enhanced Family Leave for those welcoming a new arrival, we support you throughout your journey here.
We care about our people and want to make essential healthcare accessible and affordable. That’s why we have an Opt-in Corporate health and wellbeing cash plan provided through BHSF.
We want to enable you to do your best work without having to think about whether your tech will work, so we'll set you up with a MacBook, mouse & keyboard and £250 towards setting up your WFH environment.
Pension: with Penfold. Employer contribution of 3%, employee contribution set at 5% but can be increased (relief at source or salary sacrifice).
