What are software engineering fundamentals?

Profile picture
Data Engineer at Financial Companya year ago

Alex and Rahul and the other senior people on Taro have consistently emphasized how important good software engineering fundamentals are to long-term career success as a software engineer. This is in contrast to learning the latest popular framework or area of development. Can people define what those fundamentals are and how one should go about acquiring/improving them?

Thanks!

    The definition of a fundamental is a skill that will be useful anywhere you go. Fundamentals are really interesting as it's not binary either - Even among fundamentals, some are more broadly applicable than others (applying to your personal life as well!).

    There's a lot of fundamentals that a software engineer can pick up, and I'll split the categories up into separate comments as there's simply so much to cover. Let's start with my favorite one:

    Communication

    This is by far the most important fundamental IMHO as it is literally useful in every single context, both inside and outside of work. Communication is a massive area that takes almost everyone a while to get good at, but to start, you should watch my entire Effective Communication series: Alex's Guide To Effective Communication

    Communication is also connected to many other "sub-fundamentals":

    • Building relationships - In particular, your relationship with your manager is important from Day 1 of your career, even if you start off as an intern (for advice here, watch this: Having The Proper Mentality For Manager 1 on 1s). Once you start approaching mid-level, you'll need to build strong relationships with your teammates as well. And once you get to senior/staff, you'll need to build relationships outside of your immediate team!
    • Effective meeting presence - This accounts for both participating in meetings and running them. Meetings are a staple of almost every software engineer's life, and they only become more important as you become more senior. If you're just starting off, I recommend this discussion on how to participate more in meetings: "I struggle to come up with things that add value to a meeting - What do I say?"
    • Leadership - Leadership is largely an exercise in, well, everything mentioned above and the sub-fundamentals after as well. To learn more about leadership, I recommend this video about my Meta -> Robinhood transition: [Case Study] Becoming A Tech Lead Again In Just 1 Month After Joining Robinhood From Meta
    • Mentorship - This is one of the most powerful ways to have multiplicative impact and is one of the core ways a high-performing senior/staff (or higher) engineer can scale themselves in a healthy way. Mentors need to be able to communicate concepts clearly and in an easy-to-understand way to teach more efficiently. They also need to be able to share honest feedback in an empathetic way to avoid hurting people's feeling.

    Productivity

    Similar to communication, this can also be applied outside of work. The math is simple: If you are able to get more work done per unit of time than others, you are in a great position. To get better at this, I recommend this masterclass: [Masterclass] How To Manage Your Time Optimally In Tech And Achieve More Results

    Here are some "sub-fundamentals":

    • Having a strong flow state - The idea is that when you have a long uninterrupted period of time, you are exponentially faster. This is the state I got myself into in my later days at Meta and at Robinhood: ~75% of the code I wrote came on no-meeting Wednesdays.
    • Being good at context switching - When your calendar is peppered with meetings (i.e. most senior+ engineers), it's very powerful if you're able to get something concrete done in those 15-30 minute blocks. Here's my advice on how to get better at this: "How to improve at multi tasking at work?"
    • Meeting management - This boils down to 2 things: Not going to meetings that aren't very useful to you and concentrating similar meetings on certain days to give you more focus blocks. For the first part, I'm surprised nobody has asked about how to evaluate the usefulness of a meeting yet, so I don't have a direct resource handy unfortunately. To substitute, I recommend this video: The #1 Thing To Remember With Meetings

    Quality

    This one is more specific to software engineering, and I recommend this Q&A from a Meta engineer as a starter resource to learn more about it: "For self-taught developers - How to build my own knowledge system during work?"

    Here's the "sub-fundamentals" for it:

    • Having a nose for edge-cases - I owe a huge amount of my career success to this: One of the best examples is when my attention to detail allowed me to catch a massive bug at Instagram, which I walk through here: [Case Study] Solving A Multi-Million $$ Instagram Bug. Fixing this bug saved the company $1M+ per year, and it was a large part of my promotion to E5 (senior engineer). There are many ways to build up this sense including talking to your friendly local QA engineer, dogfooding your own product, taking some time to think proactively before starting a task but my main piece of advice is to not be afraid and test diligently outside of the happy flow. I have seen so many developers write code, deploy it, timidly test only the happy flow, and submit the PR - The code's going to blow up eventually; it's not healthy to ignore the messier cases.
    • Understanding users through data - This is something that I really learned at Meta, and I'm glad I did so. Even early-stage startups (like Taro!) have analytics; it's the main way to understand whether your users love your product at scale. And once you understand your users, you can truly make the product better for them. To learn more about this, I recommend this Q&A around how to become an analytics lead: "I want to become the "data guy" in my company - How can I do that?"

    I will add one more

    Compassion

    The ability to Sympathize with others and understand where they are coming from becomes increasingly important as you progress in your career

    • Use compassion to understand the need of your teammates

      • Know them not just in work settings but take your time to understand their interest, passion and career goals.
      • This gives you an edge when collaborating with them since you know "what drives them".
    • Use compassion to understand the priorities of your managers/directors

      • Managers (especially frontline ones) have a hard job. They are basically sitting in meetings and have to deal with all the distractions. Sympathize with that and see how you can make their jobs easier.
      • This gives you an edge to really understand what are the most important things for you to deliver.
    • Use compassion to understand the priorities of other teams

      • Things that are important to you and your team might not be a priority for others. Dig in and understand what their priorities are and see how you might be able to help
      • This gives you an edge to achieve alignment when there is a conflict.
