A senior engineer's CV has one job: get you into the room. It will not get you the offer, and it does not need to be a complete record of everything you have built. It needs to make a busy hiring manager, skimming for maybe twenty seconds, decide you are worth an hour of their team's time. Most senior CVs fail at that not because the career is weak, but because the document buries the strongest evidence under responsibilities, jargon and length. Here is what actually gets read, and how to write it.
Lead with impact, not responsibilities
The single biggest difference between a CV that gets interviews and one that does not is whether the bullets describe what you achieved or what you were responsible for. "Responsible for" tells a reader nothing about whether you were any good at it. Impact does. Every bullet should answer three questions: what did you do, what was the technical decision behind it, and what changed as a result.
Weak
Responsible for the performance of the payments service.
Strong
Cut checkout latency 40% by redesigning the payments service caching layer, unblocking a launch into three new markets.
Quantify wherever you honestly can: latency, cost, uptime, throughput, team size, revenue affected. Numbers are what a skimming reader's eye stops on, and they are what separates a claim from a story. Where you cannot measure it, still lead with the outcome, not the task.
Structure for a twenty-second skim
Assume the first read is fast and shallow, and design for it. A clean structure that survives a skim:
- A two-line summary at the top that says what kind of engineer you are and what you are known for. No objective statements, no buzzword soup.
- Most recent, most relevant roles first, with the most detail. Three to five impact bullets each.
- Older roles compressed to a line or two once they stop adding new evidence. Nobody needs five bullets on a job from 2014.
- A tight tech section listing what you actually use well, not every technology you have ever touched.
Two pages is the right length for most senior engineers. One page cannot show the depth of a long career; three dilutes your strongest material. Put the best evidence where the eye lands first.
Show scope and ownership
At senior level, the reader is looking for evidence of scope and judgement, not just output. Make it visible. Did you own a system end to end, lead a project across teams, mentor other engineers, make an architecture call that a team lived with for years? Those signals are what distinguish a senior CV from a mid-level one with more years on it. Say what you owned, what you decided, and what you were trusted with, not only what you coded.
Tailor lightly, and never lie
You do not need a new CV for every role, but you should reorder and reweight so the experience most relevant to the specific job sits at the top with the most detail. Mirror the language of the job description where it genuinely matches your experience, because it helps both the human reader and the screening software recognise the fit. The line you never cross is inventing or inflating experience you do not have. A senior interview is built to probe exactly that, and it will surface a stretch fast. The cost to your credibility is never worth the interview it buys. For how to handle the numbers once you are in the process, see our guide to negotiating a tech salary in Australia.
Make it machine-readable
Many companies run CVs through an applicant tracking system before a human sees them, and a beautifully designed multi-column template can be mangled by a parser and cost you the screen. Keep it simple: a single column, standard section headings, real selectable text rather than images or graphics, and the actual keywords from the role where they apply to you. Save and send as a PDF unless the employer asks otherwise. The most elegant CV in the world does not help if the software cannot read it.
Your CV is not your autobiography. It is a twenty-second argument that you are worth an interview. Lead with impact, cut the rest, and make every line earn its place.
Get a second read
The hardest part of your own CV is seeing it the way a stranger will, because you know the context that the bullets leave out. A good recruiter reads hundreds of these and can tell you in minutes which lines land, which are invisible, and where you are underselling real work. Re:Sourced candidates get exactly that, and our Re:You AI career coach can review your CV and sharpen your bullets any time.
FAQ
How long should a senior engineer's CV be?
Two pages is the right target for most senior engineers. One page is too tight to show the depth of a long career, and three or more dilutes the strongest material. Put your most recent and most relevant roles first with the most detail, and compress older roles to a line or two once they stop adding new evidence of your ability.
What makes a good CV bullet for an engineering role?
A strong bullet leads with impact and backs it with specifics: what you did, the technical decision behind it, and the measurable result. "Cut checkout latency 40% by redesigning the payment service's caching layer" beats "Responsible for payment service performance." Quantify where you can, name the technology where it matters, and take ownership of the decision, not just the task.
Should you tailor your CV to each job?
Tailor lightly and honestly. Reorder and reweight so the experience most relevant to the specific role sits at the top and gets the most detail, and mirror the language of the job description where it genuinely matches your experience. Never invent or exaggerate experience you do not have; a senior interview will expose it quickly and the cost to your credibility is not worth it.
Do engineering CVs need to pass an ATS?
Often, yes. Many companies screen CVs through an applicant tracking system before a human reads them, so keep the format clean and machine-readable: a single column, standard section headings, real text rather than images, and the actual keywords from the role where they apply to you. Design-heavy, multi-column templates can be mangled by parsers and cost you the screen before anyone sees your work.
