Tech start-up jobs in the UK are becoming more widely available, according to new research from classified ad hoster Adzuna.

The firm’s latest study revealed that jobs in small tech companies are up 44 percent on this time last year, with 4,753 jobs currently advertised on the company’s website.

Adzuna said software developers are the most in demand, with 1,473 jobs currently listed (up 31 percent since 2012). Meanwhile, marketing and product roles were the second and third most popular, at 1,142 (up 78 percent on 2012) and 570 (up eight percent on 2012) respectively.

The study revealed that the average salary for a developer in a start-up has risen 17 percent to £45,088. Meanwhile, people working for in marketing and and product roles for tech start-ups can expect to earn an average of £37,517 and £35,199 respectively.

In London, companies such as Onefinestay, Wonga and Hailo are leading hiring charge with over 100 roles available between them, according to Adzuna. 

The research also reveals the key attributes the UK’s tech start-ups look for in new recruits. Alongside the more recognisable requirements (“highly skilled”, “able to get things done”, “great in a team” and “smart”), start-ups value personality traits such as “curiosity”, “humility” and “being nice”.

The vast majority of the UK's start-ups can be found concentrated around Old Street Roundabout in East London. A different study released earlier this year found that the area spawned 15,000 new businesses last year alone.
