Software developer job requirements: what employers ask for
By the RoleMath Editorial Team · Last updated 2026-06-18. Every figure traces to a cited source; we sell none of the options discussed. Draft pending human review.
Of every role we analyzed, software developer had the largest posting sample and the clearest verdict: certificates barely register, and demonstrated skill is everything. In a sample of public job postings we scanned (via the Greenhouse, Lever, Ashby, The Muse, and Workday public hiring APIs) for software developer roles (about 1,115 postings), employers named programming languages, cloud, and frameworks relentlessly - and a security certificate appeared in just four of them. Here is what the real software developer job requirements look like.
Key takeaways
- Across 1,115 postings, certificates were almost absent - this is the clearest portfolio-over-certificate field in tech.
- The skills employers listed most were Python (468), AWS (387), Kubernetes (344), TypeScript (318), and React (275).
- A few real projects and an active GitHub demonstrate more than any credential here.
- The occupation (Software Developers) has a national median wage of $135,980 (BLS OEWS May 2025).
Why software developer postings rarely mention certificates
In a sample of public job postings we scanned (via the Greenhouse, Lever, Ashby, The Muse, and Workday public hiring APIs), a certificate of any kind appeared in only a handful of postings (Security+ in 4). There is simply no certificate employers broadly require to hire a developer.
This is employer language from a sample of public postings - not a measure of demand, a formal requirement, or a salary signal. The honest implication: spend your effort on building things, not collecting credentials. A structured course or bootcamp can be a fine way to learn, but its value is the skills and projects it produces, not a line on your resume. What employers screen for is evidence you can write working software - which a portfolio shows and an exam does not.
Which languages and tools do employers list most?
The skill list reads like a map of modern software work. Most named:
- Python (468) and AWS (387) at the top - a general-purpose language plus cloud.
- Kubernetes (344), TypeScript (318), React (275), and Java (268).
- APIs (239), Azure (196), GCP (192), GitHub (190), and Docker (166).
No single stack dominates, which is reassuring: pick a language you enjoy, learn to ship with it (version control, testing, deploying to a cloud), and build. The most-named items are all free to learn and practice. Three or four projects on GitHub that solve real problems are what these postings are really asking for.
Degree, portfolio, and pay
A computer-science degree was preferred in some postings but frequently optional, especially when a candidate could show a strong portfolio and pass technical interviews. That makes demonstrable projects the highest-leverage thing you can build - they substitute for both a degree and a certificate in many screens.
Software developer maps to the BLS occupation Software Developers, national median wage $135,980 (BLS OEWS May 2025). As always, we keep pay at the occupation level, not as a promise tied to a course - the cited role page has the full range and outlook.
Frequently asked questions
Do you need a certification to be a software developer?
No. Across more than a thousand postings we scanned, certificates barely appeared. Software development is hired on demonstrated skill - a portfolio and technical interviews - not credentials. No certificate guarantees a job.
What skills do software developer jobs require?
Employers listed Python, AWS, Kubernetes, TypeScript, and React most often, with no single stack dominating. This is employer language from a sample, not a formal requirement, but a language you can ship with plus cloud and version control is the consistent core.
Do you need a computer science degree to be a developer?
Often not. A degree was preferred in some postings but frequently optional when a candidate could show a strong portfolio and pass technical interviews. Demonstrable projects are the highest-leverage substitute.
Is a bootcamp or a portfolio better for getting a developer job?
A bootcamp can be a good way to learn, but the portfolio it helps you build is what employers actually evaluate. Focus on shipping a few real projects you can explain - that is what these postings ask for, not the credential.
