Trinsic | Senior Product Engineer | REMOTE (Europe) | Full-time

We're building the first Identity Acceptance Network, the "Visa for ID." Humanity is editing genes, starting space tourism, and verging on artificial general intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards.

Role - Senior Product Engineer (#5 on the team; ~20% of engineering capacity). High ownership, product-minded, backend and systems leaning. - This is not a ticket-churning role. You should want to understand the competitive landscape, listen in on customer calls, bring engineering insight to product discussions, and own features end-to-end. - You should be a Barrel: someone who can take on ambiguous work, pull together the right context, make tradeoffs explicit, and drive without needing to be told every next step. Revenue is surging, we need judgement to help shape the product. - Strong backend/platform experience; generalist enough to move up/down the stack when the product needs it. - You care deeply about user privacy and data security. We work on identity. Sloppiness here is not an option.

Stack & ways of working - .NET (C#) backend, React + TypeScript frontend, Azure Container Apps, Azure SQL/Storage, Bicep IaC, GitHub CI/CD. - Remote-first; North America (CT +/- 2) or Europe (CET +/- 1). Strong async work habits; 4 hrs/week of scheduled meetings on average; pairing/huddles when useful. - We use AI aggressively and prudently. You'll have a large token budget, but we expect strong judgment around the risks.

Comp & apply

- Salary is set by our compensation philosophy, with meaningful equity. We discuss compensation early so neither side wastes time.

If you're in a workable timezone and excited about identity infrastructure, I'd love to talk.

We can have a great philosophical chat about it! Let's chat.

Since we do location based pay (based on benchmarks) it's tough to give a range as it'd be a huge range (North America has a significant variety of pay scales), and the various levels themselves in just the US have big ranges as well.

We'll address this in our first orientation call with a candidate to make sure we're in the same ball park of ranges.

But point taken, we'll look into if we can make some range indications available. For now, if you lookup compensation ranges for companies in our peer group and your geography it should match, but very happy to discuss your specific during a call.

Trinsic | Software Engineer | REMOTE (North America) | Full‑time

We’re building the first Identity Acceptance Network—the “Visa for ID.” Humanity is editing genes, starting space tourism and working on artificial intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards . We’re bringing identity into this new age, where trust is essential and becoming more so every day with AI. We enable accepting digital IDs that users already have (mDLs, BankIDs, reusable IDs) and verify users ~10x faster across 40+ networks covering 500M+ people.

Role

- Software Engineer (#5 on the team; ~20% of eng capacity). High ownership, product-minded, backend and systems leaning.

- You’ll ship fast, prune scope, and help shape our engineering culture.

- You’ve thrived in early-stage environments, can tackle fires independently, and care as much about product as code.

- Strong backend experience; generalist who enjoys moving up/down the stack.

- You care deeply about user privacy and data security.

Stack & ways of working

- .NET (C#) backend, React + TypeScript frontend, Azure, GitHub CI/CD.

Love it! Even just simply freeing my main branch would be a big win so I can keep working as well.

But no way to find out if there’s any data sent to your servers etc, unless I’m missing some links?

Perhaps to some degree, but I've never seen a skyscraper that was almost done being torn down to be re-architected and rebuilt.

Waterfall in software development was different than a Gantt chart based "project that was managed" like the construction of a bridge (an example close to my house). They added new requirements to this bridge (like they wanted the surrounding grounds to be maintained nicely, so added irrigation and gardening etc). But no new requirements were added to the foundational "here's a bridge and it needs to cross this stream from this point to that point" (high level).

Waterfall in software was continuously changing those fundamental parts. You'd be fine tuning the irrigation and needed to destruct the whole bridge because some new requirements came up. That's where the anti-Gantt and "bad waterfall" comes from, the reality is the software world as a whole moves way quicker and requirements are way more malleable, subjective than building a bridge.

How do you suggest we handle the rental market?

I assume they were talking about re-usable plastic containers vs glass. Glass breaks.

Right, but now I’m basically running a huge performance hit, need to parallelize my queries etc.

I was parsing a document recently, 10-ish questions for 1 document, would make things expensive.

Might be what’s needed but not ideal.

How would I do this reliably? Eg give me 10 different values, all in one prompt for performance reasons?

Might not need JSON but whatever format it outputs, it needs to be reliable.

What would you recommend?

There is also a Federated Credential Management (FedCN) API coming in, that should help somewhat.

Yea, that's my understanding of the introduction of the NEM 3 policy. Production of energy isn't the problem in California (aka: sun), having it stored and accessible at the right moment is. Previously people would be feeding back solar during peak sun hours and getting paid, while taking energy at night and having an effective "0 dollar use" bill if they consume the exact same amount (there is some base connection fee).

The NEM 3 policy reduces a lot what you get paid unless you contribute back during the peak use hours, they say it's "avoided cost" pricing. On the surface it seems fair, you're paying for more than generation when you use energy so you generating and contributing back during huge surplus isn't as valuable as you using during night time.

Any resources in that? Seems ridiculous. I get a “net connection fee” and can even somewhat feel comfortable with this NEM 3 thing, but what I generate should be mine to control, I could do it completely off grid if I wanted.

As mentioned in other comment, moved here recently and exploring the situation.

Huh, thank you. Moved here recently so going to have to check it out. If I have battery storage to supply my home, surplus would at least make some money right?

Why did you choose not to feed it back?

Compared to simply walking out, packing everything into your bags right away without needing to scan with either a hand terminal or "repacking" at self checkout is a lot more friction. Didn't really think it would be until I tried a couple of times in a row and it was incredible.

It would be an interesting idea to fund a company (probably best as a non-profit) that takes patent trolls to court selecting cases based on what trolls are suing and where we can find prior art. Troll the trolls.

Don't know why the company wouldn't give you a raise for increased cost of living? Plenty of companies will adjust pay based on location, including moving around. And plenty of companies adjust for inflation as well.

Of course any adjustment in pay needs to fit budget, so the company and line manager would need to have the budget to afford to. And there's probably plenty of companies that won't have this as an option or won't adjust for inflation, but there's also plenty of examples that do.

Depends how you see it. If you assume a neutral state of no incentives, adding benefits to stimulate growth and later removing this benefits once growth is achieved can be seen as "attacking this positive state" or simply "bringing back to neutral".

I moved to SoCal recently and didn't realize things like net metering even existed, so when people started to rant about these new measures I was very surprised to learn about them, and especially about people presuming these things to be "normal".

If you still have access to them, yes. Problem is if you don't. And we need to be mindful that it's easy for us to say these things being very digitally native, while there's a huge part of the population that isn't so digitally aware and relies on companies like Apple to "make everything work".

Sure, here's a first search result for the query 'locked out of Apple account': https://www.businessinsider.com/apple-not-helpful-woman-lock...

There are stories of Apple locking users out of their iCloud accounts.

If you'd want to configure this you'd probably want it as some kind of configuration in the backend that disables it.

Good ones, that deeply understand a technical subject and complexities, but are also great at the other aspects, are pretty hard to find.

Where’s that boundary between snake oil and “freedom of choice, but alternative” though? That’s the tough part here right? It’s subjective, not in it’s ultimate truth but in it’s experience by everyone.

Fair, but there’s already a lot of medical related alternative treatments and activities that cause people to give up on more established practices and causes real harm. Currently the laws allow for the government to stop a lot of that. I don’t like it, but don’t know a solution that would work, people are extremely vulnerable in these situations.

Thought the same, had a pleasant signup form for a small SaaS platform nobody really knows about, with no captcha. Then someone or some group found it and there's been a barrage of attacks varying in intensity, vectors etc. Cost us so much money in vendor costs the small company is now in danger of going bankrupt.

I appreciate the sentiment, as I had it, but rest assured any future publicly accessible form I build will get at least a CAPTCHA in front of it.

Had to look up[1] what the SMR scam was about, short summary: different disks with lower random I/O performance were sold without being marked as such.
