If you're excited about solving massive data challenges and shaping the infrastructure that supports real-time analytics and AI/ML at scale, this role is for you.

- Drive platform evolution to support AI/ML and company-wide analytics
What You'll Do
- Design and build a next-gen data platform to power product and internal use cases

- Optimize for performance, cost, and resiliency in a modern cloud environment
What We're Looking For
- 8+ years of experience in data engineering or platform architecture
- 5+ years at the Principal Engineer level or equivalent
- Deep expertise with Kafka (and its ecosystem), streaming data systems
- Strong experience with ClickHouse, Iceberg, Snowflake, or similar tools
- Cloud-native architecture expertise (AWS, GCP, or Azure)

DATA ANALYST – SUBSCRIPTION PRODUCT
£45,000 + STRONG L&D CULTURE
REMOTE-FIRST | LONDON HQ
A data-driven subscription business is looking for a curious and proactive Data Analyst to join their growing analytics function. You’ll work as the embedded analyst within a cross-functional product tribe, collaborating closely with product managers, designers, and engineers to drive strategic decisions across user engagement and retention.
This is a remote-first company, but you’ll be asked to attend occasional team days in the London office (roughly once every 2-3 months).
THE ROLE
Reporting into the Head of Data Science & Insights, you’ll be the go-to analyst for your product tribe. This isn’t a role where you’ll be working off a backlog of stakeholder tickets – they’re looking for someone who’s naturally curious, confident in owning their analysis roadmap, and keen to surface ideas that lead to real business impact.
Your day-to-day will include:
-
Deep-diving into user data to optimise free trial performance and early-stage user journeys
-
Designing and analysing A/B tests to inform product development
-
Building and maintaining DBT pipelines and ensuring data models are fit for purpose
-
Collaborating with engineers to ensure Snowplow tracking is implemented correctly
-
Partnering across product, engineering, and design to identify and drive opportunities
YOUR SKILLS
-
Strong SQL skills – you’ll be writing it every day
-
A background in data analysis within a digital product environment
-
Experience with experimentation (A/B testing) is a strong plus
-
Experience with subscriptions or optimising user onboarding would be highly desirable
-
Python skills are a nice-to-have, but not essential
-
A self-starter mindset and comfortable working autonomously within a tribe model
WHAT YOU’LL GET
-
£45,000 base salary
-
Excellent learning and development budget with protected time for upskilling
-
Internal progression programmes and support
-
Remote-first culture with flexible working
-
Collaborative, high-impact team working on meaningful product challenges
PROCESS
-
Introductory interview with the hiring manager
-
Light case study (no data, focused on approach)
-
Technical interview with two team members
-
Culture interview with a stakeholder from another function
This team is in early stages of hiring, so you’ll be getting in at the ground level with no one else currently in process.
If you’re a data analyst looking for a strategic role within a collaborative product environment – and you want to work where your ideas genuinely shape direction – this could be the right move.
