When I joined a healthcare data SaaS company as their first senior technical hire, nobody called me the CTO. The CEO needed someone who could build the product, and that’s what I did. I reported directly to him, I wrote code, I designed the database, I directed a small, contracted engineering team, and I started making architecture decisions that, as it turned out, would shape the company for years.

I think about that now because the “should we hire a CTO?” conversation comes up constantly with early-stage founders. And most of the time, what they actually need is closer to what I was doing: someone who can own the technical side of the business end-to-end, from architecture through delivery, while building the team that will eventually take on parts of that work.

Starting With What’s There

The company had a contracted, fractional engineering team when I arrived. They were capable, and I directed their work while also writing code and building database structures myself. For a while, this worked well enough. But as the product grew and the client base expanded, the fractional model hit a ceiling. The team couldn’t make enough progress against what the business needed.

That recognition – that the current approach has run its course – is one of the earlier judgment calls in a role like this. We brought on a dedicated DBA, a QA team, and contracted for a full-time offshore engineering team. The pace changed. What was possible changed. And my job changed too. I was still hands-on in the code and the database design, but now I was also coordinating releases across time zones, resolving blockers, and mentoring developers I’d never met in person.

The Architecture Decisions You Feel Later

Some of the decisions I made in that first year or two echoed through every phase of the company’s life afterward. I consolidated dozens of separate client databases into a single multi-tenant architecture. At the time, the motivation was practical. Onboarding new data was painfully slow, and each client’s database was its own maintenance burden. The consolidation cut time-to-availability by 75%. What I didn’t fully appreciate yet was that this same decision would make the platform scalable enough to support an acquisition years later, and manageable enough to migrate when the time came.

Another call was migrating infrastructure to Azure in phases rather than all at once. System availability went from below 94% to 99.99%. That sounds like a clean before-and-after, but in practice it was months of incremental work – moving pieces while keeping the existing system running for clients who depended on it daily.

The thing about these decisions is that you’re often making them without much of a safety net. There was no architecture review board, no senior engineer to debate with. I was both the architect and one of the people building on top of the architecture every day. That turned out to be an advantage. The feedback loop between designing something and living with it keeps the decisions grounded in a way that a more removed vantage point sometimes misses.

Building the Product Under Real Pressure

I built the company’s primary revenue-generating product, a healthcare provider reporting engine that generated several million dollars in annual revenue. The decisions ran from database schema through API design to front-end UX. In a small company, this is what product ownership actually looks like for the engineering leader. The CEO brought the market insight and the client relationships. I shaped what was technically feasible and figured out how to deliver it.

What I’d emphasize about this phase is the time pressure. Clients had deadlines tied to their own business cycles. The market wasn’t going to wait for the architecture to be perfect. Every week involved tradeoffs between moving fast and making technical choices I’d have to live with for years. Some of those tradeoffs I got right. A few I’d make differently now. The ones I got right tended to be the ones where I understood the downstream implications well enough to know where shortcuts were safe and where they’d compound into real problems.

This is where deep technical knowledge becomes a product advantage. When you understand what the platform can actually support, you make faster, more confident decisions about what to build next and what to defer. Those conversations with the CEO were more productive because I could say “we can do that, and here’s what it’ll cost us later” rather than just “yes” or “let me check.”

What Happens When It Works

When the platform was solid and the team was functioning well, the company got acquired. And everything I’d built got stress-tested in ways I hadn’t anticipated.

I served as the technical program owner through the acquisition, making sure systems, data flows, and client delivery stayed intact during the transition. Then I led the post-acquisition integration, migrating systems, data, and clients into the acquiring company’s enterprise platform. The multi-tenant architecture that made onboarding efficient also made migration manageable. The team structure that enabled delivery also provided the institutional knowledge the acquirer needed to understand what they’d bought.

Having been through that full cycle – proof of concept to production platform to acquisition to integration – the thing that stands out most is how connected it all was. Nothing in the later stages was disconnected from choices made in the first year or two. The architecture decisions, the team decisions, the product tradeoffs – they all showed up again during due diligence and integration, for better or worse.

What I’d Tell a Founder Making This Hire

If you’re looking for your first senior engineering hire, the question to focus on is whether the person can work across architecture, product, team-building, and delivery at the same time. That’s a specific combination, and it’s different from what you’d look for in a pure architect, a people manager, or a product thinker. And it is a different mindset than a CTO of a mid-size company.

Ask about architecture decisions they made without a committee. Ask how those decisions played out over time. Ask when they recognized that their team model wasn’t working and what they did about it. Ask about product tradeoffs – where they moved fast, where they pushed back, and what they learned from the ones that didn’t go as planned.

The title you put on this role matters less than the scope. The person who builds your platform, hires your team, and partners with you on product direction is doing this work whether you call them Head of Engineering, VP of Engineering, or something else. The important thing is that they’ve done it before and can tell you what it actually looked like.

What did your startup’s first engineering hire look like? Was the scope what you expected, or did it evolve into something different?
