Cover Letter for Tech Jobs in Switzerland
In Switzerland, a cover letter for a tech role is not a personality piece, it is a short proof of relevance. Whether you are applying to a start-up in Zug, a scale-up in Zurich, or Google Switzerland, the letter must answer one question in under a page: why you, why this role, with concrete technical evidence. Here is how to do it right.
- Start-ups: 3-4 short paragraphs, link to GitHub or portfolio is expected
- Multinationals: more structured, ATS-optimised with keywords from the job posting
- Name specific technologies, with results, not just listings
- Swiss companies do not expect a US-style sales pitch: restraint signals confidence
- One page maximum; a half-page letter is acceptable for start-up roles
Start-ups and scale-ups: brevity and evidence
In Swiss tech start-ups, a well-maintained GitHub profile often outweighs a polished cover letter. The letter serves three purposes: establish relevance to the role, mention one or two specific technical contributions with outcomes, and point the recruiter to the strongest evidence (portfolio, GitHub, notable project). "I built a distributed event-processing pipeline in Go that reduced p99 latency from 800ms to 90ms in production" is a sentence that gets remembered. "Passionate software engineer with 5 years of experience" is not.
The tone in start-ups can be slightly more direct than in traditional companies. Long introductory sentences and formal salutations feel out of place. Get to the point by paragraph one.
Multinationals (Google Zurich, UBS Tech, Zurich Insurance): ATS and structure
Large Swiss employers and international tech companies use applicant-tracking systems before a human reads your application. A cover letter that does not contain keywords from the job posting may be deprioritised before it is read. If the role specifies "distributed systems", "Kubernetes", or "data engineering", those terms need to appear naturally in your letter, not as a list, but embedded in sentences that show applied context.
Recommended structure: an opening that references something specific about the company or team, a core paragraph with two to three quantified technical achievements relevant to this role, one sentence about what you bring that is not already visible in the CV, and a concise close requesting a conversation.
Pasting your stack as a bare list to "beat the ATS" often backfires: applicant-tracking systems weigh keywords embedded in real sentences higher than keywords dumped in isolation. A letter that lists "Kubernetes, Go, Terraform" with no context can score worse than one that uses each term once inside a sentence describing what you actually built with it.
A Swiss tech recruiter remembers one sharp metric far longer than any string of self-descriptive adjectives.
Portfolio and open source: making the letter shorter
If you have a documented portfolio or active open source contributions, the cover letter can be shorter and act as a navigation guide. Rather than describing every skill, reference the specific project most relevant to the role: "Project X on my GitHub directly addresses the distributed caching problem described in your posting, it is a Redis-backed cache layer built for 50M+ daily requests." This approach shows both technical depth and communication ability.

Frequently asked questions
Do I need a cover letter for tech jobs in Switzerland?
If the posting asks for one, yes, and it is read. For start-up roles where a portfolio is available, a brief email-style note may suffice. For corporate roles or senior positions, a structured letter is expected and weighed in the screening decision.
Should I list my entire tech stack in the cover letter?
No. Select the two or three technologies most relevant to this specific role, and show them with concrete context and results. The full stack belongs in the CV. A letter that reads like a technology catalogue does not differentiate you.
How long should a cover letter be for a Swiss tech company?
For start-ups: three to four paragraphs, half a page is acceptable. For larger companies: four to five paragraphs, one page maximum. Swiss recruiters value precision, longer is not better.
What is the 13th month salary in Switzerland?
The 13th month salary in Switzerland refers to an additional monthly salary paid once a year, typically in December. It is included in annual salary benchmarks as standard: when a Swiss employer quotes CHF 120,000 per year, this normally means 13 monthly payments of approximately CHF 9,231 each, not 12 payments of CHF 10,000. The 13th month is governed by the employment contract or collective agreement (GAV), not by statute. It is subject to social contributions (AHV/ALV) and income tax. Always clarify with a prospective employer whether a quoted annual figure includes or excludes the 13th month.
How do Swiss notice periods work for employment contracts?
Under Swiss law (Code of Obligations, Art. 335c), notice periods during probation (default 1 month, up to 3 months by agreement) are 7 days. After probation, statutory notice periods are: 1 month during the first year, 2 months in years 2 to 9, and 3 months from year 10 onwards. Notice must be given in writing by end of calendar month (or end of the agreed notice period month). Contractual or GAV notice periods can be longer but cannot be shorter than statutory minimums. Protected periods exist (illness, accident, pregnancy) during which termination is suspended or prohibited.
