Tips/advice for starting a new job?

Take lots of notes on things you notice. Build relationships with people. Figure out what they do and what they care about. That way you'll know who to go to when you have questions, issues, need favors. Have short intro meetings with lots of people, ideally informal. Lots of coffee. Ask them what challenges they're facing, and what you and your team can do to help them. Consider doing some of those things, especially those things that your manager / team / team lead / etc wants you to do. Ask your manager and co-workers who you should start building relationships with.

1. Manage Up: no matter your level, there's someone you're going to report to or be accountable to. Get to know them, their function and focus areas, expectations, how they operation and how they judge value and success.

2. Network: regardless of the size of your organization, make a list of people you want to meet across different groups/departments. Make it a point to schedule 1:1 time to get to know them. Much like the guidance in Pt 1 above, get to know what they do, how they operate, what they value and how they judge value and success. Ask them about where they need help and if they see opportunities for you to help in your new role. And always ask them for referrals to other people you should meet next.

3. Regular Review Intervals: do this first for yourself, and try to establish a more regular progress and planning session with your boss. Quarterly is good to keep this somewhat informal as it will be outside regular performance review cycles, but regular enough to ensure timeliness and value. It's also important for your own sanity to keep a realistic view on how things are going and whether they map to your personal needs and plan. We all get bogged down in the day to day BS, so this forces a time to reflect and put things in perspective.

4. Plan A Vacation: whether you have something booked or not, block a vacation for sometime in the next 6-9 months. It's easy to get approvals when you're starting out, if you need that, and it gives you a purpose to find something meaningful to fill that block of time so you have something to look forward to.

Get amped up about the business domain.

Learn by watching and being inquisitive, but do not judge publicly.

Don't advocate for what you perceive could be better about anything the company, team, or even individual does until you understand how the current situation evolved.

You want to be seen as someone who notices real problems the business faces, rather than trivial concerns which some new hires tend to point out in a wholesome attempt to display their knowledge to the new team on day one.

Let your previously acquired experience come to be known over time through action.

They are hiring you to participate in the production process and they are expecting a burn-in period. You should identify how you can shorten that period to a minimum to begin delivering value quicker than expected for the average new hire.

Be genuine.

Good luck!

Google your Boss. One of the smartest people I know just started a new job and when I asked them what they knew about their boss's hobbies and interests, they hadn't googled them yet.

After my suggestion, they discovered their boss had may of the same interests and hobbies. Knowing what people care about helps with bonding and small talk. And while these things may appear trivial at times to us tech folk, small talk is the social lubrication that really helps build relationships.

Be humble and don't get too excited about fixing and improving things on day/week/month 1. Just listen and observe and be patient for the first 3-6 months. There are often more to things than meets the eye and it will take time for you to get your head around it.

Take a vacation before starting and enjoy your brief moment of freedom!

read some psychological articles about interpersonal interactions. Group processes. Do not break existing unwritten rules. There is always a some sort of climate in a team/workplace. Observe how other people interact formally and informally. Be more like them and after you are accepted as group member - you then can pursue your own goals. Get to know other people before you roll out your ambitions.
