Learn how to write a CV that showcases founding engineer and startup experience. Real example from JobSprout's creator, what hiring managers look for, and how to position breadth as a strength.
Startup engineers face a unique CV challenge. You have built entire products from scratch, worn every hat imaginable, and shipped features that directly moved business metrics. But when you try to write it all down, it can look unfocused - like you could not decide what you wanted to do.
This guide is different from our general tech CV guide. That guide covers backend engineering with a focus on system scale and specialisation. This one is specifically for engineers who have worked at early-stage startups and need to translate that experience for their next role - whether at another startup or a larger company.
The example in this guide is my own CV. It landed me my current role at Lawhive after working as a founding engineer at a cleantech startup and then at Darktrace. I built JobSprout partly because I was frustrated with how hard it was to create a CV that properly represented startup experience.
The Startup Engineer's Dilemma
At a startup, your job title rarely captures what you actually do. "Founding Engineer" might mean:
Architecting the entire technical stack
Building the MVP mobile app
Setting up CI/CD pipelines
Interviewing candidates
Debugging production issues at midnight
Making coffee when the machine breaks
This breadth is valuable. But on a CV, it can read as "jack of all trades, master of none" if you present it wrong.
The key insight: you need to tell a story of intentional breadth, not accidental chaos.
What Hiring Managers Actually Think About Startup Experience
I have been on both sides of the hiring table. Here is what hiring managers at different company types are looking for:
At Other Startups
Startup hiring managers love startup experience. They want to see:
Ownership mentality: You did not wait for someone to tell you what to do
Shipping velocity: You got things out the door, not just planned them
Business awareness: You understood why you were building what you were building
Adaptability: You handled ambiguity and changing requirements
The risk they are evaluating: "Will this person need too much structure to be effective here?"
At Larger Companies (Scale-ups, Enterprise)
Larger company hiring managers are more cautious about startup experience. They want to see:
Depth in at least one area: You can go deep, not just wide
Collaboration skills: You can work within existing systems and teams
Process awareness: You understand why processes exist (even if you have opinions about them)
Scale experience: You have worked on systems with real users, not just MVPs
The risk they are evaluating: "Will this person struggle with our processes and team dynamics?"
The Common Thread
Both want to see impact. The difference is how you frame it:
For startups: "I built X from nothing and it now does Y"
For larger companies: "I built X that improved Y by Z%, working with teams A and B"
CV Structure for Startup Engineers
Here is the structure that works for startup experience:
Contact Information (including GitHub/Portfolio/LinkedIn)EducationProfessional Experience (reverse chronological)Skills (grouped by category)Projects (side projects that show initiative)
Why This Structure Works for Startup Experience
Education early. Controversial take: for startup engineers applying to larger companies, education provides credibility that your startup experience might not. A Cambridge MPhil or Berkeley CS degree signals "this person can learn complex things" even if your startup failed.
Experience section carries the weight. This is where you translate startup chaos into structured achievements. More on this below.
Skills grouped by domain. Startup engineers often have broader skill sets. Grouping by domain (Frontend, Backend, Infrastructure) shows intentional breadth rather than random exposure.
Projects section matters. Side projects demonstrate that you build things because you want to, not just because someone pays you. For startup engineers, this signals the ownership mentality that made you effective at a startup.
Real Example: Founding Engineer to Senior Role
This is my actual CV. It got me hired at Lawhive after working as a founding engineer at Carno (a cleantech startup) and then at Darktrace.
What Makes This CV Work
The most important thing about this CV is what is not on it. Everything that does not directly support the target role has been cut. Many people think additional content cannot hurt - it can. Padding signals that you do not know what matters. A focused one-page CV shows confidence and clarity of thought.
Notice the header: name, contact, and three relevant links (GitHub, LinkedIn, personal site). Recruiters who want to dig deeper have clear paths to explore. This is strategic - it keeps the CV scannable while giving curious readers more to find.
The experience section tells a clear story: founding engineer at a startup, then senior role at a scale-up, then senior role at a fast-growing legal tech company. Each step shows progression and increasing scope.
Section-by-Section Breakdown
Experience Section: The Startup Role
Here is how I presented my founding engineer experience:
Founding Engineer | Carno | 2021-2022Cambridge, UK- Founding full-stack engineer at a cleantech startup aiming to accelerate domestic decarbonisation by simplifying and optimising heat pump installation and sourcing with a mobile surveying application.- Architected and developed the MVP mobile app using React Native, TypeScript, Node.js, and Firebase.- Improved code base quality by introducing CI/CD pipelines covering linting, code formatting, automated testing using Jest and Cypress, and maintaining in-line and wiki documentation.
What this does right:
Context first. The first bullet explains what the company does and why it matters. This is crucial for startups that hiring managers have never heard of.
Technical specificity. "React Native, TypeScript, Node.js, Firebase" tells a hiring manager exactly what stack I worked with. No guessing.
Process maturity. The CI/CD bullet shows I understand engineering best practices, not just hacking things together. This is important when applying to larger companies.
What is deliberately omitted:
Revenue numbers (the startup was early-stage)
Team size (it was tiny)
Vague claims about "wearing many hats"
Experience Section: The Scale-up Role
The Darktrace section shows I can work in a larger organisation:
Senior Software Engineer | Darktrace | 2022-2025Cambridge, UK- Delivered key projects, including a dynamic reporting dashboard and real-time monitoring page, improving customer visibility and streamlining workflows.- Refactored monolithic code into reusable UI views using NPM packages and micro-frontends.- Led UI development for Darktrace /CLOUD, coordinating cross-functional teams and collaborating on API architecture for the flagship security product.- Maintained and developed the internal UI component library (20+ projects, 1000+ imports)- Championed developer experience with automatic branch deployment CI work and led re-architecting to React Query for async state management.
What this does right:
Scale indicators. "20+ projects, 1000+ imports" shows the component library had real adoption.
Leadership signals. "Led UI development" and "coordinating cross-functional teams" shows I can work with others, not just solo.
Technical depth. The React Query and micro-frontends bullets show I can make architectural decisions, not just implement features.
Shows I am genuinely full-stack, not just "I touched the backend once"
Demonstrates modern tooling awareness (Remix, tRPC, Supabase)
Includes infrastructure and observability - signals I can own things end-to-end
Projects Section
The projects section shows initiative:
JobSproutAI-powered CV and cover letter builder using novel client-side Typst PDF compilation, multi-provider AI orchestration (OpenAI, DeepSeek, Perplexity), intelligent document parsing, and real-time editing.CorpifyAn open-source boilerplate for quickly launching SaaS applications with Remix, Supabase and Shadcn.
Why include side projects:
Demonstrates I build things without being told to
Shows current technical interests (AI, modern frameworks)
Strong: "Architected and shipped the MVP mobile app using React Native and Firebase, establishing the technical foundation for the product."
Pick the 2-3 most impressive things you did. The rest can come up in interviews.
2. No Context for Unknown Companies
Weak: "Founding Engineer at Carno"
Strong: "Founding Engineer at Carno, a cleantech startup simplifying heat pump installation"
Hiring managers have not heard of your startup. Give them one sentence of context.
3. Underselling Scale
Weak: "Built the mobile app"
Strong: "Built the mobile app from scratch, now used by 500+ installers across the UK"
If your startup had any traction, mention it. Even small numbers are better than no numbers.
4. Overselling Chaos
Weak: "Thrived in a fast-paced, ambiguous environment with constantly changing priorities"
Strong: (Just show it through your achievements, do not say it)
Everyone claims they can handle ambiguity. Your achievements should demonstrate it.
5. Ignoring the Target Company
A CV for another startup should emphasise different things than a CV for Google. Tailor your framing:
For startups: Emphasise ownership, shipping speed, business impact
For larger companies: Emphasise collaboration, process, technical depth
Startup-Specific Tips
Handling Failed Startups
Startups fail. This is normal. Here is how to handle it:
Do not hide it. Gaps raise more questions than honest failures.
Frame what you learned. "Built MVP that validated market assumptions" is fine even if the company shut down.
Focus on your contributions. The company's outcome is separate from your work quality.
Translating Startup Titles
Startup titles are often inflated or meaningless. Here is how to translate:
"CTO" at a 3-person startup → "Founding Engineer" or "Technical Co-founder"
"Full-Stack Developer" → Keep it, but show the breadth in your bullets
"Head of Engineering" with no reports → "Senior Engineer" or "Technical Lead"
Honesty builds trust. Inflated titles get caught in reference checks.
Showing Business Awareness
Startup engineers often understand business context better than engineers at larger companies. Show this:
"Built payment processing that enabled $40K MRR within 6 months"
"Reduced infrastructure costs by 60% through architecture optimisation"
"Shipped feature that increased user retention by 25%"
Connect your technical work to business outcomes.
Demonstrating You Can Go Deep
The "jack of all trades" concern is real. Counter it by showing depth in at least one area:
Mention specific architectural decisions you made
Include technical blog posts or talks you have given
Reference open source contributions in your specialty area

Yes. Hiring managers understand that startups fail. What matters is what you built and learned. Hiding it creates suspicious gaps.
How do I explain leaving a startup?
Be honest and brief:
"Company ran out of runway" - fine
"Pivoted away from my area of expertise" - fine
"Wanted to work at larger scale" - fine
Do not badmouth founders or investors.
Is startup experience valued at big tech companies?
It depends on the role and team. Some teams specifically seek startup experience for its ownership mentality. Others prefer candidates with experience in large codebases and processes.
Research the team you are applying to. If they are building something new within the company, startup experience is often valued.
How many years of startup experience is "enough"?
There is no magic number. What matters is what you accomplished. Two years at a startup where you shipped a product is more valuable than four years at a startup that never launched.
Should I list my startup equity?
No. Equity is private financial information and irrelevant to your qualifications.
