Developer seniority

Lead engineer or architect
Sets the RxJS architecture, reviews the team's code and plans migrations, upgrades and scaling work.
A small blended pod
A RxJS developer with backend, QA or design support, coordinated by one delivery owner for larger scopes.

Why Techsleight
Why hire through Techsleight.
What you can hold us to — and what happens if something is not working.
You choose who joins
You see profiles and talk to the RxJS developer before anything starts, and nobody joins your team without your say-so.
Senior, production engineers
People who have shipped and supported real products — reviewed for code quality, testing habits and communication, not just a CV.
They work your way
Your repositories, tickets, stand-ups and review rules. Daily written updates and a weekly demo keep the work visible.
No lock-in
Hourly, dedicated or project-based, with short notice periods. Scale up for a launch and back down after it.
You own the code
Code, IP and documentation belong to you from day one. NDA before any detailed conversation, if you need one.
UK-focused delivery
UK business hours, GBP pricing and a contract with a UK company. Our engineers are based in the UK and India.
A whole team behind one hire
Backend, QA, DevOps and design colleagues are there when the RxJS work needs them — without you hiring for each role.

Questions we get asked.
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
How much does it cost to hire a RxJS developer in the United Kingdom?
RxJS developer rates at Techsleight Labs start from £20/hour for flexible work and from £2,900/month for dedicated monthly capacity. Fixed-price RxJS projects are quoted after discovery, once scope, integrations, risks, and timeline are clear.
How quickly can a RxJS developer start?
Most RxJS engagements start within 5–7 working days of sign-off, and urgent work can sometimes start within 48–72 hours. For larger projects, we first confirm scope, architecture, milestones, and the right senior engineer fit before kickoff. We support UK teams with written updates, planned demos, and timezone-aware handover.
Can I hire one RxJS developer or a full team?
Yes. You can hire a single RxJS developer, add a small pod with QA and DevOps, or ask us to manage the complete project. We match the model to your current team, delivery pressure, and budget.
Are your RxJS developers senior?
Yes. Our hiring pages are built around senior production engineers, not junior bench resources. Every developer is reviewed for commercial project experience, communication quality, code quality, testing habits, and ability to work inside existing teams.
Do you work with existing RxJS codebases?
Yes. We often join existing RxJS projects to fix performance, unblock releases, add features, improve test coverage, or modernise architecture. We start with a codebase review so the first sprint is practical rather than theoretical.
What happens if the RxJS developer is not the right fit?
Tell us early. We will look at the cause with you — the brief, the onboarding or the match — and agree the next step together, such as more technical oversight, a different engagement model, or ending the engagement on the notice terms in your contract. The goal is a useful working relationship, not lock-in.
Will we own the RxJS code and IP?
Yes. You own the code, documentation, infrastructure setup, and product IP created for your project. We can sign an NDA before discovery and work inside your repositories, cloud accounts, and project management tools.
Do you provide post-launch RxJS support?
Yes. After launch we can stay on for monitoring, bug fixes, performance work, security updates, roadmap features, and handover support. Many clients keep a small retainer after the main build so the product keeps improving.
