DevOps & automation
CI/CD, infrastructure as code, containers and release engineering. We replace the manual runbook with something repeatable, reviewable and dull — which is what production should be.

Ship faster. Stay up. Prove it’s secure.
DoJu Systems is an independent engineering consultancy. We build the delivery pipelines, the reliability practice and the security controls that let a team move quickly without breaking things — and hand them over so you can run them without us.
What we do
Three disciplines, one engineering team
Most problems we are called in for sit across all three — a release process that is slow because it is fragile, and fragile because nobody can see what it is doing.
Site reliability engineering
SLOs and error budgets, observability that answers real questions, and an incident process that does not depend on one person being awake. Fractional SRE for teams without a reliability function.
SRE servicesSecOps & DevSecOps
Scanning, secrets, least privilege and detection built into the pipeline — producing the evidence Cyber Essentials, ISO 27001 and client security reviews ask for.
SecOps servicesAdditional expertise
Where the network itself is the problem
Two specialisms we are brought in for on their own, alongside the core engineering work.
Corvil & low latency
Corvil Certified Experts
Subject-matter expertise in Corvil latency and packet-capture analytics for electronic trading and market data — capture architecture, decoders, troubleshooting and RTS 25 timestamping.
Corvil expertiseBusiness IT from scratch
Network, servers, identity, backup and monitoring — designed, installed and documented. For businesses with no IT function yet, or an estate nobody has looked after in years.
Building your ITWho we work with
Teams that have outgrown doing it by hand
Software teams
Product and platform teams whose release process has become the constraint, and who need delivery, reliability and security to stop fighting each other.
Businesses under scrutiny
Companies facing a certification deadline, a client security review or an insurance questionnaire that the underlying controls cannot currently support.
Trading & market data
Trading firms, brokers, venues and bank infrastructure teams who need latency measured accurately and explained honestly.
How we work
Senior engineering, no lock-in
- You get the engineer, not a layer of account management. The person scoping the work is the person doing it.
- Everything is written down. Diagrams, runbooks and configuration in version control, handed over so your team can run it without us.
- Vendor-neutral by default. We recommend what fits the problem and the budget, not what carries a margin.
- Measured, not asserted. If we claim something got faster or safer, we show you the numbers behind it.
