Capabilities

Everything you need from CWJobs, nothing you do not

Our CWJobs scraper handles every layer of the platform: job listings, dynamic salary bands, recruiter profiles, and search results. We manage the JavaScript rendering, session state, and anti-bot circumvention.

Full Job Postings

Extract title, full description, skills, location, and contract type directly from the listing page.

Salary Band Normalisation

Parse raw salary strings into structured minimum, maximum, currency, and period fields.

Tech Stack Parsing

Identify specific programming languages, frameworks, and tools from unstructured job descriptions.

Contract Type Tracking

Categorise roles into permanent, contract, temporary, or part time arrangements.

Remote Work Status

Classify positions as fully remote, hybrid, or office based using location metadata.

Recruiter vs Direct Employer

Flag whether a job is posted by a recruitment agency or a direct employer.

Pagination & Search Coverage

Deep scraping of search results for any keyword or location combination.

Historical Expiration Tracking

Detect when jobs are closed or removed to calculate time to hire metrics.

Scheduled Updates

Configure continuous pipelines at hourly or daily cadences with change detection.

Under the hood

How our CWJobs pipeline handles the hard parts

Job boards invest heavily in scraping detection to protect their inventory. Here is how we stay resilient.

Anti-bot layer
Bypassing StepStone network protections

CWJobs is part of the StepStone group and uses strict bot mitigation. Our crawlers use UK residential ISP proxies with realistic browser fingerprints and full cookie session management to bypass Cloudflare and PerimeterX.

JavaScript rendering
Full Playwright execution for dynamic content

Many job details and apply buttons load dynamically. We run full Playwright browser sessions with JavaScript execution to capture data that headless HTTP clients miss entirely.

Schema stability
Resilient selectors for job descriptions

Job descriptions are often unstructured HTML. We use a combination of CSS selectors, XPath, and regex pattern matching to reliably extract salary bands, tech stacks, and contract types regardless of formatting.

Change detection
Only re-scrape new or updated jobs

We maintain a hash index of active job IDs. Subsequent runs only push new jobs or status changes, reducing compute cost and downstream processing load.

Monitoring & alerting
24/7 pipeline health checks

Every run emits structured logs. We alert on null-rate spikes, missing fields, and coverage drops. We respond before you notice.

Applications

Who uses CWJobs data and how

Teams across industries use cwjobs.co.uk data to build competitive products and smarter operations.

01
Market Rate Analysis

HR teams and recruiters track salary bands across specific tech stacks to ensure competitive compensation.

02
Competitor Intelligence

Monitor hiring velocity and role types at competing firms to deduce their product roadmaps.

03
Lead Generation for Recruiters

Identify companies actively hiring direct and pitch agency services for hard to fill roles.

04
Tech Trend Analysis

Track the rise and fall of demand for specific frameworks or programming languages over time.

05
Job Board Aggregation

Niche job boards sync relevant IT listings to their own platforms to increase inventory.

06
Economic Forecasting

Financial analysts use IT hiring volume and salary trends as a macro indicator for the UK tech sector.

Why DataFlirt

"CWJobs holds the most concentrated dataset of UK IT hiring demand, but extracting clean salary bands and tech stacks requires a managed pipeline."

Most teams underestimate the investment required: reliable CWJobs scraping requires residential proxies, full JavaScript rendering, CAPTCHA handling, daily selector maintenance, and anomaly monitoring. DataFlirt absorbs that complexity so your engineers can focus on the analysis, not the infrastructure.

Infrastructure

Infrastructure powering the CWJobs pipeline

Open-source tooling on proven cloud infra — no vendor lock-in, full observability.

ScrapyPlaywrightPython 3.12RedisPostgreSQLApache AirflowAWS LambdaS3CloudWatch2CaptchaCapSolverResidential ProxiesDockerKubernetesGrafanaPrometheus
Scrapy + Playwright Stack

Scrapy handles crawl orchestration and deduplication. Playwright handles JavaScript rendering, cookie sessions, and interaction flows to bypass bot protection.

Residential Proxy Infrastructure

We maintain pools of UK residential ISP proxies. Rotation happens per request with sticky sessions where required to maintain access.

Cloud-Native Orchestration

Pipelines run on AWS Lambda and ECS. Airflow handles scheduling, dependency management, and SLA alerting. State is stored in managed Postgres.

Common questions.

About cwjobs.co.uk scraping, legality, and pipeline operations.

Ask us directly →
Is scraping CWJobs legal?

Scraping publicly available job listings is generally permissible under applicable law. DataFlirt targets only public, non authenticated job and company data. We do not extract personal candidate data or circumvent authentication walls.

How do you handle StepStone bot protection?

We use UK residential ISP proxies, full Playwright browser sessions with realistic fingerprints, and request timing modelled on human behaviour. We monitor for CAPTCHA rate spikes and trigger solver queues automatically.

Can you extract exact salary bands from text?

Yes. We use regex and NLP parsing to extract minimum, maximum, currency, and pay period from unstructured salary strings.

How fresh is the data?

We can configure pipelines to run hourly for high priority searches, or daily for full category sweeps. You define the cadence.

Do you track when a job is closed?

Yes. By maintaining a state table of active job IDs, we can flag when a job URL returns a 404 or is marked closed, allowing you to calculate time to hire.

What is the minimum viable engagement?

Our packages start at defined keyword or category sweeps with weekly delivery. For full site extraction, we price based on volume and frequency. Contact us for a quote.

Can I request a sample dataset before committing?

Yes. We provide a sample run of up to 500 job listings as part of the pre engagement scoping process so you can validate schema fit and data quality.
