Company Overview
Vellmont Advisory Ltd is a Nairobi‑headquartered PropTech real‑estate & mortgage‑investment platform serving local Kenyan buyers and diaspora investors. Our small tech team currently consists of one frontend developer only. We are hiring a hands‑on mid‑senior backend engineer who will act as our de‑facto backend technical lead. We run an
AI‑first rapid‑iteration culture
: engineers leverage AI coding tools to multiply delivery speed, while you own architecture, database design, code review and production quality. AI is your efficiency multiplier, not your decision‑maker.
Job Summary
This is NOT a junior‑level role that only implements pre‑written API specifications.
You independently own end‑to‑end backend delivery: database modelling → API design & implementation → frontend integration → testing → deployment & production maintenance. You will build our core real‑estate business entity relationships: Property → Unit → Listing → Landlord / Property Manager → Tenant → Lead → Viewing → Offer → Transaction
You collaborate closely with frontend, sales & CRM teams to deliver our Rental V1 module on tight iteration timelines.
Key
Practical Redis caching, S3‑style object storage for image/file upload
API security: input validation, access control, rate‑limiting, audit logging
Write unit & integration tests; build lightweight CI/CD auto‑deployment pipelines
AI‑first engineering (Mandatory requirement)
Daily use AI coding assistants for: code generation, SQL & migration scripts, API documentation, test‑case writing, debugging, code refactoring & log analysis.
Expect interview question：
“If you need to launch Rental V1 within 7 days working with one frontend developer, how will you utilise AI tools?”
Rule：
You own all technical decisions; AI accelerates your execution.
Cross‑team collaboration
Joint debugging with frontend; integrate backend system with existing CRM; iterate
3+ years hands‑on backend development
(exceptional candidates with strong practical results may be considered even without exact year count).
Proven relational‑database modelling
for complex multi‑relation business scenarios; you can decompose business entities instead of building oversimplified flat tables.
Hands‑on
REST‑API design, Git workflow, Linux server administration, AWS or equivalent cloud services.
Must use AI coding tools in daily development workflow for build, debug, refactor & test writing.
Strong plus
: past building CRM / Marketplace / SaaS / PropTech / Real‑estate platform / E‑commerce / Booking‑style systems.
Startup‑minded independent engineer: interpret business requirements, break down tasks, make technical trade‑off decisions, self‑debug and push code to production,
without waiting for fully‑detailed PRD documents
.
Good written & spoken English for cross‑functional team communication.
Note: We do not rigidly lock programming‑language stack. Outstanding architecture & database engineering capability weighs higher than exact stack match.
