Onboarding Tips For Senior+ Engineers

As a Senior Engineer (or Staff or Principal) coming into a new company, there will be some expectation that you are bringing in domain knowledge. Your opinion can be valuable. A few ways to have immediate impact:

- Contrast how your current company operates compared to past companies
- Ask questions about why certain processes exist or don't exist

As you ramp up, remember to "**respect what came before.**" You don't want to disparage existing systems without realizing that it was best designed at the time of construction with the constraints and knowledge *at the time*.

As a senior engineer, you also need to lay the foundation for team and org-level impact. This means you invest extra time in building relationships and meeting other senior/staff/principal engineers.

Entry-Level Engineer (L3) Describes Most Important Skill - Uriel Sejas

Uriel is a new grad engineer at Slack.

- Most important skill: understand and follow patterns in the codebase. There's likely a well-defined template or approach you can follow to complete your work. 
- Advice: take time to connect with other engineers. An engineer on a different team (build system or UI framework) can share something that otherwise would have taken hours/days to figure out.

The Defining Trait Of Mediocre Software Engineers With Debugging

One of the main differences between a low-performing software engineer and a high-performing software engineer is that the high-performer looks for true solutions to bugs instead of hacky ones like the low-performer does. Don't suppress the symptoms when fixing bugs - Treat the root cause as well.

This video is a clip from our debugging masterclass. You can watch it here: [[Masterclass] How To Become A Debugging Master And Fix Issues Faster](https://www.jointaro.com/lesson/ioR6WzamAIUTpySLAr7o/masterclass-how-to-become-a-debugging-master-and-fix-issues-faster/)

[Case Study] How To Become A Data Guru As An Engineer (w/ Senior Director of DS Mo Shahangian)

Mo has had a successful career at the intersection of data science and engineering at companies like Pinterest, Meta, and Epic Games.

Mo talked about the biggest data mistakes and how the job changes as you navigate seniority levels. He also shared his contrarian approach to promotion that has worked so well in his career. 

## Data knowledge for engineers:
- Data science is an overloaded term. The high-level goal for anyone working with data is to surface insights that will inform decisions. 
- Being insightful isn’t enough -- you need to surface **actionable** and **causal** relationships.

Everyone needs a reminder correlation != causation. Have some tools to remind yourself.
- Which way does the causal arrow go?
- Remember [Goodhart’s Law](https://en.wikipedia.org/wiki/Goodhart%27s_law)

## Career growth
- At the most senior levels, leaders are business owners/product leaders, not functional leaders.
- At more junior levels, it’s the opposite, there needs to be order and a separation of responsibility. The best people learn how to work, not only within their lane, but across.

Career success comes from being deliberate:
- A career is a series of decisions
- These decisions come with tradeoffs
- Those best at navigating tradeoffs emerge as leaders
- "Deliberate" means that you are both intentional and calculated

Mo started out building data systems at UCLA, joined Pinterest during hypergrowth, and eventually became a Senior Director of Data Science at Meta, and recently joined Epic Games at the leadership level. Connect with Mo: https://www.linkedin.com/in/mohammad-shahangian-b040188/

When Should You Switch Teams Or Companies? - Daniel Tomko's Perspective

Daniel Tomko spent much longer at the companies in his career compared to most engineers: 11 years at Microsoft and 8 years at Meta. Within these companies, Daniel did various team changes.

- Switching companies has a higher "transaction cost" compared to switching teams.
- At a large enough company, you have tons of interesting technical challenges and people to work with.

System Design Series: Taro Playlists [Part 5] - Data Model

You can [find the full system design doc here](https://docs.google.com/document/d/15WaM8Ojan82g0m2mtz6kC2Hiyj0Q6VbjfqRmVNDI3qw/edit?usp=sharing) - Feel free to use it as a template for when you're designing systems at your job!

The concrete details are covered in the doc linked above, so this summary will focus on the "meta" context behind this part and additional commentary:

- Always define the data model if applicable. It is the "core operating unit" of your system - Everything revolves around it. That's pretty much what CRUD is: You have some data model and the entire ecosystem revolves around manipulating it properly.
- Define the table/collection(s):
  - What is its name?
  - What does it represent? If you can include a visual aide on how it's actually rendered for the user, that makes things a lot clearer.
- Define the fields on your model:
  - What is its name/key?
  - What is its type?
  - Is it required?
  - What does it represent? This should include information on what kind of key it is (e.g. primary key) if applicable.
- Illustrate the model to make it really clear. JSON is really good at doing this as it's very readable. There are many free incredible JSON formatters online (Alex used them all the time to make project specs).

"Is Taro hiring?" - 8/18/2022

If you're searching for a job, check out [our in-depth video on how Taro can help you do just that](https://link.jointaro.com/e5Swdksn8886KrQs9).

- **Not right now, but hopefully soon** - We want to make sure that when we do hire a full-time employee, we treat them very well and pay them top-of-market. We also want to make sure we're running as stable a ship as possible, especially in this economy - We don't want to hire someone just to lay them off within a year. This requires a lot of capital, more than we have with just the YC investment.
- We're raising our seed round now, and if this goes well, we should be able to hire a full-time engineer, maybe 2.
- Our dream is to turn Taro into a huge, financially sound company and then hire folks who have been supporting us for a long time, all the way back to the Tech Career Growth days.
- If you want to help, continue using Taro, letting us know how we can improve, and sharing the app with your friends and colleagues! The more we grow, the faster we can scale up Taro and achieve our vision of empowering every software engineer in the world to be happier and more effective in their careers.

20 Years Of Fighting Procrastination [Part 13] - Your Phone Is A Menace

Your phone can be both a powerful tool and a massive productivity killer—how you manage it makes all the difference. Here are the core points from the lesson:

- To prevent unconscious distractions, keep your phone physically out of reach during deep work and turn off nearly all notifications by default
- Replace passive phone checking with active forecasting—mentally plan what you’ll do next based on the outcome of a task to stay engaged
- Use batching strategies (e.g. scheduled email checks) to reduce context switching and maintain focus
- Aim to move up the PEM framework: from Pleasure (mindless scrolling) → Engagement (being immersed in your craft) → Meaning (working toward a long-term purpose)

15 SWE Years In 1.5 Hours [Part 3] - Writing Good Code

With the rise of helpful online resources like StackOverflow and especially genAI tools like ChatGPT, learning to write code is now easier to ever. Where engineers earn their stripes (and the right to be paid $100k+ per year) is with their *code quality*. This lesson teaches you:

- The only true way to learn how to write good code
- Why copy-pasting what FAANG engineers do isn't a shortcut to writing good code
- How to objectively measure the quality of your code

Grow From Mid-Level To Senior Engineer [Part 20] - Mentorship

Mentorship is one of the most skills to master as a software engineer, especially at senior levels. It is both a way for you to do some good and scale yourself. This lesson teaches you: 

- The difference between passive and active mentorship
- Ways to provide passive mentorship to teammates
- Why you should consider taking on an intern as a mid-level engineer growing to senior
- The jump in quality when it comes to mentorship advice given by a mid-level engineer vs. a senior engineer

Grow From Mid-Level To Senior Engineer [Part 10] - Code Review

Writing code is great, but so is reviewing code. In fact, being great at reviewing code is more impactful than being great at writing code 90%+ of the time! This lesson teaches you:

- How the writing code vs. reviewing code dynamic changes as you get to senior
- Why senior engineers tend to review more code than they write
- How senior engineers expand their code review scope while mid-level engineer code review scope tends to be more constrained with a real-life example
- The difference between a senior engineer code review comment vs. a mid-level engineer code review comment

Grow From Mid-Level To Senior Engineer [Part 7] - Take Greater Ownership

As a senior engineer, you need to show strong ownership. Many mid-level engineers are told this by their manager but are unsure as to what that means. This lesson teaches you:

- Why the "points" you get for impact aren't just correlated to the impact of the projects you work on
- How to get more credit for each project you work on
- What it means to show stronger, more holistic project ownership with a real-life example from Alex's past at Instagram

Master The Behavioral Interview [Part 11] - Interviews Are A 2-Way Street

One of the easiest ways to tank your career as a software engineer is to join the wrong company or team. Despite this, so many software engineers squander their time in behavioral interviews to uncover extremely valuable information about the quality of an organization. This lesson teaches you:

- Why not having thoughtful prepared questions to ask the interviewer makes you look really bad in a behavioral round
- The critical career importance of behavioral interviews being a 2-way street

Negotiation Course: Helpful Phrases During Negotiations
