Can you define a CTO?

Many co-founders are looking for a CTO to join them but can you define the role of a CTO?

The role of the CTO changes with the size and type of the company. The CTO of IBM is a person with a completely differrent skill set than the CTO of a startup.

When your funding comes from Friends, family and yourself, your CTO should be the person who can implement your product him/herself along with some management skills to guide a few developers. THis gives you an option to have him/her build the whole system, build critical parts of the system and outsource everything else, or outsource everything and have him/her manage the outsourced work. Generally, at this stage, a 2-pizza team is sufficient, and you need the CTO to be able to manage this team. At this point, you don't really want to hire a dedicated manager.

Once you grow to 50 people, you need the CTO to know how to hire the right mix of people to make this organization function. At this level, being able to create a sustainable R&D organization  is all about setting the right culture and hiring the right people.  This person will also probably need to be more outward facing. S/he will probably be the technical face of your company, and will need to be able to provide credibility to your organization. Also, at this point, this person will also need to focus more on the comptetion and the market than on the day to day R&D

Once you get to 500 people, then your CTO is more or less a people manager. He would still need to technical know how to understand the problem, and propose solutions and provide strategy. However, s/he would be really relying on other people to do the leg work, and mostly providing direction. This kind of person is a very differrent person than the one you need when you were a 5 person company. This CTO is more of a "tell other people what to do" kind of person than a "get things done" kind of person.

From http://ctorole.com/, roles of the CTO in a startup:

1. Architect

The CTO is the main architect of the software. This includes:

  • Choosing the technologies, language and infrastructure to build the product with.
  • Choosing the development tools, like IDE, source control, logging, tests, etc.
  • Designing the software architecture, modules, and components.
  • Building the dev roadmap, with coordination with the other founders regarding priority of features.
  • Deciding on coding standards and development protocols.
  • Writing and managing any software related documentation (for example company internal wiki page etc.).
  • Designing the Database. This includes choosing DB solution, designing its tables and data relations, design it to scale, etc.
  • Constantly exploring new tools and technologies to improve development efficiency and product quality.
  • When someone introduce a new tool or technology that integrates with the software or affect the dev cycle, the CTO must examine and approve or reject it.
  • When another founder or employee design a software component or a module, the CTO must review it and suggest changes if needed.
  • The CTO should have the final word on all design decisions, as he is the founder with the deepest understanding of the general architecture.

Exceptions:

Without diminishing the list above, its important to remember that some architectural decisions may have financial or scheduling implications. The CTO should not make decisions that exceed the budget or deadline.

2. Developer

Since it takes some time for a startup to start hiring devs, the CTO must also act as the main (and often only) developer on the team. At least until hires are made. This includes:

  • Developing the product itself, the MVP and other side experiments that the founders decide to test.
  • Testing the product and writing automatic tests when possible.
  • Overseeing any external development force (outsourcing, other founder temporarily coding, etc.).
  • If the startup provides a service or an API, the CTO should constantly monitor and assure its health and quality.
  • Breaking down development tasks and evaluating dev times and release dates. The CTO should also be responsible to learn and improve from scheduling mistakes.
  • Managing releases, tags, and versions history.
  • Developing or providing scripts and tools for the other founders.

As the startup grows bigger and the dev teams expand, the CTO work less as a developer and sometimes stop coding altogether.
The involvement of the CTO in directly writing code should be up to him, provided he has enough time and resources to be coding (or there's a special justification for it).

3. Team Manager / VP Engineering

When the startup only starts to grow and hire, its the CTO's job to manage the dev team and act as the team leader as well as the VP engineering (until those roles are fulfilled). This includes:

  • Breaking down tasks for the dev team.
  • Training new employees and designing training program if possible.
  • Doing code & design reviews.
  • Making sure the dev team produce quality and tested code.
  • Making sure the dev team comply with the coding standards and protocols defined by the CTO.
  • Monitoring the devs progress and making sure they keep up with the roadmap.
  • Doing occasional talks with the team to make sure they are happy and in-sync with the company direction.
  • Building the culture of the dev teams.
  • Overseeing the entire dev cycle, from initial designs to delivery.
  • Helping devs with coding problems and challenges they can't handle. The CTO must be an exceptional developer and a problem solver that the team can relay on.
  • Recruiting and evaluating new hires. New programmers should not be hired without the CTO approval.
  • Being the direct supervisor of the technical staff.

Passing the Team Manager Role

When the dev team grows big enough, usually the role of the team leader is passed down to one of the senior engineers of the team (and sometimes someone from outside is hired for the job).
On the event of hiring / promoting a Team Manager:

  • The team manager would report directly to the CTO.
  • On technical disagreements, the CTO will always have the final word.
  • The level of direct involvement of the CTO in the dev team would be subjected to the CTO choice.
  • The distribution of responsibilities and authority between the CTO and the team manager would be decided by the CTO.
  • The choice of the team manager must be approved and accepted by the CTO.

Passing the VP Engineering Role

When the company grows even bigger its common to hire a VP Engineering to supervise the dev teams (however, its also common for the CTO to remain a part-time VP engineering).
On the event of hiring / promoting a VP Engineering:

  • The VP Engineering would report directly to the CTO.
  • On technical disagreements, the CTO will always have the final word.
  • The level of direct involvement of the CTO in the dev team would be subjected to the CTO choice.
  • The distribution of responsibilities and authority between the CTO and the VP Engineering would be decided by the CTO.
  • The choice of the VP Engineering must be approved and accepted by the CTO.

4. IT

Just like with devs, most startups start without a proper IT team. Its up for the CTO to take up that role until IT is hired. This includes:

  • Setting up and maintaining the company servers, databases, and all external services and tools.
  • Making sure the servers and data are secured and protected against common attacks.
  • Managing things like domains, SSL certificates, CDN, and other server-related and web components.
  • Managing the company's site, landing pages, and other misc services.
  • Helping the non techy founders with their general IT problems.

When the startup grows bigger usually some IT personnel is hired, and report to the CTO.

5. Founder & Executive

With all the roles and responsibilities above its important to remember that the CTO is also a founder and an executive-level personnel, and as such he is entitled to be involved in the strategy planning and big decisions of the company.Its easy for a CTO to gradually "sink down" into just the architect & dev roles, especially since there's so much work there, but its important that the CTO remains an integral force in the company's direction and be in complete sync with the other founders, aware and part of all major decisions.While this section may sound redundant, we actually heard a lot of complains about founders that feel their CTO is not involved enough in the company management, or CTOs that sometimes feel "left out" from important decisions. Therefore this section was included.
