SCLZY Job Description
SCLZY builds and delivers outbound campaigns for B2B firms in finance niches, using free public data (Companies House bulk register, officer records, charges data) instead of buying lists, and dedicated cold email infrastructure instead of a client's own domain. We need someone to own the full technical build behind a live campaign: the data, and the infrastructure it sends from.
You'll be working from existing, documented Python scripts and build checklists, not building this from a blank page. The pipeline, the known gotchas, and the QA gates before anything goes live are already written down.
What you'll do
Data
- Run and adapt existing Python scripts against the Companies House bulk register (7-part alphabetical snapshot, ~5.7m companies) to build target lists per niche, filtered by size band, sector, charge/borrowing history, and other signals
- Find and verify company domains and named contacts (director names via the Companies House officers API), using scripts already built for this
- Catch data-quality problems before they reach a send list: wrong size bands, name-match contamination (e.g. a search for "corporate finance" catching banks and lenders, not just brokers), parked domains, stale contacts
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.

- Buy and set up sending domains separate from a client's primary domain
- Provision mailboxes (M365), configure SPF, DKIM, DMARC, MX, and a tracking domain on each
- Run inbox warmup and monitor sender reputation and blacklist status before a domain goes into live sending
- Load the target data and copy into the sending platform (PlusVibe) and launch campaigns against the QA gate checklist
- Flag and fix deliverability issues (bounce rate, spam placement) as they come up
What we're looking for
- Strong infrastructure and system administration skills, with experience designing, deploying, and maintaining email-related or similar outbound systems.
- Networking and network security skills, including understanding of DNS, email authentication (SPF, DKIM, DMARC), IP reputation, and secure configuration of cloud and server environments.
- Hands-on troubleshooting experience across infrastructure, networking, and outbound email systems, with the ability to diagnose and resolve deliverability and performance issues.
- Experience working with monitoring tools, logging, and metrics to track system health and optimize throughput and reliability.
- Familiarity with cloud platforms (e.g., AWS, GCP, Azure) or dedicated email infrastructure providers is highly beneficial.
- Comfort working in a remote, asynchronous environment and collaborating with GTM, operations, and technical teams.
- Strong documentation habits and ability to translate technical concepts into clear guidance for non-technical stakeholders.
- Relevant technical degree or equivalent hands-on experience in infrastructure engineering, system administration, or related fields.
