Having grown rapidly to establish themselves as a trusted global leader in this field, providing readily accessible content via a range of subject-specific websites and digital platforms, their close-knit team work remotely, but with a collaboration hub currently in London where they enjoy getting together to explore and share ideas on a monthly basis.

With a flexible approach to working and with excellent benefits and opportunities for career development and advancement, this really is an excellent time to join.

Benefits include:

• Remote working
• Flexible hours
• 25 days holiday
• Pension

What’s required of the CTO?

Location: Fully Remote (UK only)
Level: Staff / Principal
Type: Permanent

The Opportunity

We’re partnering with a well-funded, product-led technology company building advanced backend systems to solve problems that traditional automation has never been able to crack.

This is not incremental engineering.

You’ll be joining a senior, highly capable engineering team that has already shipped a complex production platform and is now scaling it to handle extreme concurrency, massive data volumes, and highly sophisticated workflows.

If you enjoy designing systems that need to be fast, resilient, and correct at scale, this is the sort of role that doesn’t come around often.

Building systems that process large volumes of unstructured data with strict latency requirements

Setting technical direction and raising engineering standards across a senior team

Leading architectural decisions that will underpin the platform for years to come

Working closely with product and domain experts to translate real-world complexity into elegant technical solutions

This is a hands-on architecture role, not a people-management position.

What We’re Looking For

This role is aimed at engineers who have already “been there” technically.

Core experience:

Extensive backend engineering experience (typically 10+ years)

Expert-level Python, with deep understanding of async patterns and performance optimisation

Proven experience designing and scaling distributed systems

Strong background in API design, data-intensive systems, and service architecture

Track record of building platforms that operate reliably under heavy load

Nice to have:

Experience with TypeScript / Node.js in complex systems

Exposure to AI-driven platforms, document processing, or workflow engines

Experience in regulated or high-reliability environments

Cloud-native architectures and containerised deployments

What’s On Offer

Competitive base salary aligned to Staff-level impact

Meaningful equity in a fast-scaling business

Flexible PTO

Pension contribution

Fully remote working setup

If you’re a Staff-level backend engineer who enjoys solving problems most teams never even attempt, this is one worth exploring.

Staff Engineer - Backend (Fully Remote)

Location: Fully Remote (UK only)

The Opportunity

We’re partnering with a well-funded, product-led technology company building advanced backend systems to solve problems that traditional automation has never been able to crack.

This is not incremental engineering.

You’ll be joining a senior, highly capable engineering team that has already shipped a complex production platform and is now scaling it to handle extreme concurrency, massive data volumes, and highly sophisticated workflows.

If you enjoy designing systems that need to be fast, resilient, and correct at scale, this is the sort of role that doesn’t come around often.

What You’ll Be Doing

• Designing and evolving the core backend architecture of a complex, high-throughput platform
• Solving hard scaling problems across concurrency, performance, and reliability
• Building systems that process large volumes of unstructured data with strict latency requirements
• Setting technical direction and raising engineering standards across a senior team
• Leading architectural decisions that will underpin the platform for years to come
• Working closely with product and domain experts to translate real-world complexity into elegant technical solutions

This is a hands-on architecture role, not a people-management position.

What We’re Looking For

This role is aimed at engineers who have already “been there” technically.

Core experience:

• Extensive backend engineering experience (typically 10+ years)
• Expert-level Python, with deep understanding of async patterns and performance optimisation
• Proven experience designing and scaling distributed systems
• Strong background in API design, data-intensive systems, and service architecture
• Track record of building platforms that operate reliably under heavy load

Nice to have:

• Experience with TypeScript / Node.js in complex systems
• Exposure to AI-driven platforms, document processing, or workflow engines
• Experience in regulated or high-reliability environments
• Cloud-native architectures and containerised deployments

What’s On Offer

• Competitive base salary aligned to Staff-level impact
• Meaningful equity in a fast-scaling business
• Flexible PTO
• Pension contribution
• Fully remote working setup

If you’re a Staff-level backend engineer who enjoys solving problems most teams never even attempt, this is one worth exploring.
