The most active employers in this slice are Flitzen Technologies UK Limited, Coursereport, Quantaleap and Cloudodyssey. Every role is detected on the employer's own careers page rather than reposted from another board, so what you see here is the vacancy as the employer wrote it.
Of the 374 roles, 26 publish a salary. The median advertised ceiling is £65,000. The middle half of the market sits between £50,000 and £70,000, so anything above the upper figure is a genuinely strong offer for JavaScript jobs in London. Contract day rates are annualised at 230 working days a year, so permanent and contract pay compare like for like.
On working pattern, 48% are fully remote, 16% are hybrid and 1% are contract rather than permanent. By seniority, 68% at mid level and 13% at senior level. Filter by any of these on the left.
Employers hiring for JavaScript in this slice most often ask for it alongside Python, React, AWS, PHP, SQL and Azure. That co-occurrence is counted from the live listings on this page, not from a fixed list, so it moves with the market.

Questions about these roles
How many JavaScript jobs in London are there right now?
We are tracking 374 live vacancies across 145 employers. The crawler revisits employer careers pages continuously and roles disappear from this page as soon as they come down, so the count reflects what is genuinely open today.
What do JavaScript jobs in London pay?
The median advertised ceiling is £65,000, based on the 26 of these roles that publish a figure. The middle half of the market runs from £50,000 to £70,000. Contract day rates are annualised so they compare against permanent salaries.
Can these roles be done remotely?
48% are advertised as fully remote and 16% as hybrid. The rest are on-site or do not say — where an employer is silent we leave it blank rather than guessing.
Are these contract or permanent roles?
1% are contract or fixed-term and the remainder are permanent or unstated. A quoted day rate is treated as contract even when the advert does not use the word.
Which employers are hiring?
The most active right now are Flitzen Technologies UK Limited, Coursereport, Quantaleap, Cloudodyssey and Voizac. Every vacancy links straight to that employer's own careers page — we are an aggregator, not the hiring company, and there is no middleman between you and the application.
What other skills do these roles ask for?
Most often Python, React, AWS, PHP and SQL. That is counted from the live adverts on this page rather than a fixed list, so it tracks what employers are asking for this month.
How much does a JavaScript developer earn in London?
£65,000 is the middle of what is advertised here, which is 18% above the £55,000 median across UK IT as a whole. Read it as the ceiling an employer is advertising towards rather than an offer: 348 of these adverts name no figure at all, and those are the ones where asking early is worth most.
Can you work from home as a JavaScript developer in London?
239 of the 374 live adverts here offer home working in some form — 179 fully remote and 60 hybrid. Fully remote means the advert states no office requirement; hybrid means it names a split.
Are there entry-level or graduate JavaScript developer jobs in London?
16 of the roles on this page read as graduate or junior level, which is 4% of what is live. Level is read from the job title, so a role advertised without one is counted as mid-level and may still be open to less experience.
What job titles are used for this role?
Employers on this page advertise it as UI/UX Designer, Frontend developer, Product Designer, joomla developer and AI Engineer. Searching one wording and not another is the most common way people miss vacancies, which is why this page groups them.
How much experience do these roles need?
The largest group is mid level (68% of the page). Seniority is read from the job title, so a role that does not signal a level in its title is counted as mid-level.
