ANSI brings enterprise-grade rigour to UK technology recruitment. We place specialist technology and professional candidates into permanent, contract, and IR35-compliant roles — with the same vetting standards our global engineering clients rely on.
We focus on the disciplines that matter most to enterprise and FinTech organisations — from engineering and data to risk, compliance, and leadership.
Full-stack, backend, frontend, mobile. Java, Python, .NET, Node.js, React, cloud-native development.
AWS, Azure, GCP architects, DevOps engineers, platform engineers, SRE, Kubernetes, Terraform.
Data engineers, data scientists, ML engineers, analytics leads, and AI/NLP specialists.
Security architects, pen testers, SOC analysts, IAM specialists, and information security managers.
Test managers, automation engineers (Selenium, Cypress, Playwright), performance testers, and SDET roles.
Product managers, product owners, programme managers, scrum masters, and delivery leads.
Technology risk, model risk, regulatory change, IT audit, and compliance specialists in financial services.
CTO, CIO, VP Engineering, Head of Engineering, and Technology Director placements at enterprise scale.
We operate across all standard UK hiring structures and ensure full IR35 compliance for every contract engagement — protecting both you and the candidate.
Full-time employment placements with full vetting, offer management, and onboarding support.
Fixed-term, day-rate, and project-based contracts. All engagements are IR35 assessed and structured correctly.
Trial engagements that convert to permanent hire — ideal for assessing fit before long-term commitment.
Retained and contingency search for senior technology leadership appointments.
Since the 2021 IR35 reform, organisations are responsible for determining the employment status of their contractors. Getting this wrong carries significant HMRC penalties.
Our UK recruitment practice is built around the sectors we know best — those where technical rigour, regulatory awareness, and speed-to-hire matter most.
Investment banks, asset managers, trading firms, and clearing houses. We understand the technical domains — from FX systems to risk engines to regulatory reporting.
High-growth FinTech firms, payment processors, and embedded finance providers. We recruit the specialist engineering talent that builds the UK's financial infrastructure.
Lloyd's market, retail insurance, and reinsurance firms. Technology and data professionals who understand the specific demands of insurance systems and actuarial models.
Large-scale enterprise technology transformations across FTSE 100 and FTSE 250 organisations. Programme delivery, architecture, and specialist engineering.
Magic Circle law firms, consultancies, and professional services organisations requiring technology, data, and digital transformation specialists.
NHS trusts, healthtech companies, pharma, and life sciences organisations building digital health infrastructure and data platforms.
We combine market knowledge with ANSI's rigorous vetting to deliver shortlists faster, with higher hit rates, and fewer wasted interview cycles.
Our Commitment: First quality shortlist within 5 business days of receiving a detailed brief. Most placements completed within 3–5 weeks.
We take the time to understand the role, the team, the culture, and what "excellent" looks like — beyond the job description.
Active candidate network, targeted headhunting, and specialist community access. We don't just post on job boards.
Every candidate is screened for technical capability, communication, culture fit, and genuine motivation before they reach you.
We co-ordinate the process, prepare both sides, and provide feedback loops that keep the pipeline moving.
Salary benchmarking, offer negotiation, reference checks, and right-to-work verification — all handled by ANSI.
30/60/90-day check-ins with both client and candidate. If something isn't working, we act quickly.
We work with some of the UK's most ambitious technology and financial services organisations. If you're a technology professional looking for your next permanent or contract role, we'd like to hear from you.
We maintain live roles across our client base. Reach out to discuss current opportunities — most are not publicly advertised.
