In-house feel, nearshore
Pinecone Developers
Pinecone demos are easy and production indexes are not, particularly once latency, cost and relevance start pulling against each other. We embed engineers who have run vector search under real load, full time and on your working day.
- Real production Pinecone experience, not sandbox trials
- Latency, cost and relevance balanced deliberately
- Full time in your team, on British hours

Vetting
You see two people - not 200 CVs.
Engineers vet engineers
A senior engineer runs a live technical conversation on the candidate's real stack, not a recruiter working from a keyword list.
Live coding, not take-homes
Real problems solved in front of an assessor, with anti-cheating checks. You see how they actually work, not what they submitted overnight.
A full profile, not a CV
Every candidate arrives with a CV, interview summary, coding-test breakdown and rate in pounds. You decide on evidence.
Every tab is a stage a candidate has to clear. Six of them, all run by our own internal engineers at Cloud Employee, before you see a name.

Relevance is a judgement call, not a setting
A vector index that returns plausible but wrong results fails silently, so we vet for the evaluation discipline that catches it early. Vetting is CTO-led with live pair programming, engagements roll monthly with 30 days notice, and all-in cost sits 50 to 75% below a comparable British hire.

Got questions?
The questions CTOs and founders ask.
Somewhere between 50 and 75% less than a comparable British hire when salary, employer national insurance, pension, recruitment fees and overheads are all included. We hire UK-based engineers where that is what a client wants. More often the best value sits in Eastern Europe, the Philippines or Latin America, where the standard matches Britain at a much lower cost. Our aim is the strongest quality-to-cost ratio we can find, genuine vector search capability at a price that keeps working for the business. Pinecone is new enough that dedicated UK experience barely exists.
Pinecone is a fully managed vector database, used to store embeddings and retrieve the most similar items at speed, most often as the retrieval layer in AI applications. Teams choose it precisely because it is managed. There are no indexes to shard, no clusters to babysit, and capacity scales without an infrastructure project, which lets a small team ship semantic search or retrieval-augmented generation quickly. The trade-offs are the mirror image, a proprietary service dependency, costs that grow with scale, and internals you cannot tune the way you can with an open-source engine.
The Pinecone API is small, so look for retrieval judgement rather than product-specific knowledge. The engineer's real work is everything around the index, choosing embedding models, chunking documents sensibly, designing namespaces and metadata filters, and combining vector scores with keyword signals when pure similarity is not enough. Ask whether they can measure retrieval quality, because relevance you cannot measure will quietly rot as your data grows. AI has made it trivial to stand up a demo that retrieves something, the scarce skill is proving it retrieves the right things.
Give them a retrieval problem with messy real documents and judge how they reason about quality, not how fast they call the API. Ask how they would chunk a contract differently from a chat log, and how hybrid search changes things for names and codes that embeddings fumble. Then the discriminating question, how would you prove to me that retrieval got better after your change. Strong candidates describe building an evaluation set from real queries, weak ones say the results looked better.
Demand tracks the wider surge in retrieval-augmented AI products, and Pinecone sits prominently in that wave, so yes, the skills are sought after. Whether to build on it is a sharper question. Managed vector search is worth paying for when your team is small, your timeline is short, and retrieval is a component rather than your core intellectual property. It deserves harder questioning when usage pricing dominates or data residency demands self-hosting. The underlying skills transfer across every vector store, so an engineer hired for Pinecone is not stranded if you migrate later.
Yes, our engineers work with AI tools daily, which is fitting when the job itself is building AI retrieval infrastructure. Trust comes from verification habits we test for directly. In vetting we assess whether candidates use AI tooling well, and retrieval work gives that a concrete meaning, generated pipeline code often works on clean sample data and fails on your real documents, so we watch whether a candidate insists on testing against realistic inputs. Code is cheap to produce now and expensive to judge, so we hire the judgement, and a human always decides.
The process is CTO-led rather than recruiter-driven, because retrieval engineering competence is invisible to keyword matching. Candidates take a technical assessment, then a live pair programming session with a senior engineer working on realistic retrieval problems, where we see whether they think in evaluation sets and cost, or just in API calls. A cultural fit screen and our psychometric assessment, built specifically for software engineers, examine how they think and work. You are interviewing matched candidates within 7 working days, with the engineer embedded in about two weeks.
You are typically interviewing matched candidates within 7 working days of a requirements call, and developers are often embedded and pushing code within about two weeks. From there it is a rolling monthly contract with 30 days' notice, one monthly fee, and no placement charges. You can scale up or down as the work changes, and you pay nothing to interview.
There is a two-week money-back guarantee, and if you want to continue we replace the developer free of charge. In practice this rarely comes up, because you interview a shortlist of two candidates who have already passed a CTO-led technical assessment and a live pair programming session, so the fit question is largely settled before anyone starts.
