Paramark | Software Engineer (L4) | San Francisco HYBRID (3 days/wk) or REMOTE (US) | Full-time | $199K–$249K + equity

Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.

In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.

Founded 2023, ~16 people, $8M from Greylock, cash-flow positive. Reasonable working hours: when the Mercury News covered the return of 996 culture, we were the counterexample. "We don't think early stage startup life requires 18-hour days, or even 12-hour days." https://www.mercurynews.com/2025/08/25/silicon-valley-startu.... 4 weeks PTO plus federal holidays, medical/dental/vision (100% of employee premiums, 50% for family).

Looking for 8+ years, full-stack. Some exposure to statistics, experimentation, or A/B testing helps.

Stack: TypeScript, React, Python, Postgres. Google Cloud, Kubernetes, FastAPI, taskiq.

Process: intro call; technical phone screen; one-day onsite in SF (travel covered for remote candidates)

VOYGR (YC W26) | Founding Product Engineer | San Francisco | ONSITE | Full-time | $150K-$200K + 0.5%-2.0% equity

I'm Yarik, cofounder and CTO. Before this I spent 20 years in tech with 10+ years running infra, ML and search teams at Google, Meta and Apple.

We love maps and build location/businesses APIs for AI apps and agents. If ChatGPT tells you a restaurant is open and it actually closed in March, that's the problem we fix. We check whether a business still exists, whether its hours and details are right, and enrich it with what's being written about it on the web (news, articles, events). Customers get all of it through one API and we solve it for them with our models which use all available sources and ai voice agents which can confirm the information.

You'd be one of the first engineers. Some weeks that's search and ranking, some weeks it's data pipelines or evals, some weeks it's the API or something a customer asked for yesterday. You'll have a big say in what gets built, not just how.

Stack: Python, FastAPI, Postgres/PostGIS, DynamoDB, Redis, AWS (EKS), our own ML models plus LLM APIs (OpenAI, Gemini, Anthropic).

What I'm looking for: - 2+ years shipping production systems, or fewer if your background is unusual and you can show what you've built - real experience with at least one of: search/IR, large-scale data processing, ML systems, API design - you already use Claude Code, Cursor or similar as part of how you work - geo/POI data experience is a plus, not required

Fair warning: we are a small team, fast pace, and there could be nights and weekends. If that's not where you are in life right now, totally fine, this just isn't a good fit.

Process: a short note on why you, a 30 min call with me and then Vlad, a technical deep dive, then a paid trial project.

Discord | Senior Software Engineer, Application Security | REMOTE (US West Coast) or San Francisco, CA | $196K-$245K base + equity

Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.

We are hiring a Senior Software Engineer to join the Application Security team. This is hands-on product engineering: building security features that protect user accounts, strengthening authentication and session security, and improving security-critical services. You will work directly with product teams to ship user-facing account security tools and address emerging threats.

Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.

Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and writing code across languages, experience shipping production software, and sound judgment on prioritizing real risk over checklist security. Experience with authentication, passkeys, MFA, or session management is especially relevant.

Location: Remote from the US West Coast. If you are in the Bay Area, our SF office is an option. Relocation to the Bay Area is not required.

Interview process: recruiter call, coding round, HM interview, virtual onsite, decision.

Apply: https://discord.com/jobs/8656854002

Trustworthy Technology | Earth | Part Time | REMOTE | Anything

Hi, we are a small group trying to bring the "trustworthy" feature back to tech. Curating and building a FOSS+ toolset, storefront, and eventually online service—all to support freedom, privacy, and informed consent—on device and on the net.

We've written our thoughts and research down at: https://trustworthy.technology/ and we have a few geeks starting projects at: https://codeberg.org/aol

First off, you'll notice that you've probably not heard about this project before. Next, the message is a bit scattered, and the "programmer art," while arguably not horrible isn't winning any awards either, haha.

That's where you come in.

You are one of the few folks who really cares about this stuff, and also a graphic/product designer, or perhaps a digital marketer, communicator or "people whisperer." (Being in the EU would be helpful as well, to work from the digital sovereignty angle, though not required.) Geeks are welcome too.

Some of us are unemployed and currently donating our time. Maybe you are too, or retired/cashed-out and bored. Consider this another FOSS-like project. We hope the store/service will make money, but we're not there yet.

Interested? Let's chat at: https://trustytech.zulipchat.com/join/ivui3uglp2at3tyltau7jj...

BTW, if/when you join please say hi and let us know what kind of projects you're interested in.

NeverBlink | Community & Ecosystem Lead | Remote (EU)

We are building a HuggingFace / npm for ontologies. Ontologies are what gives data meaning.

We are looking for people to get this tech into the hands of as many devs in AI & data as possible. You don't need to know what are ontologies, we can teach you that. Some background in agents or analytics preferred.

Apply if you like working with OSS communities, technical writing, and physical events (e.g., workshops at conferences). You get ownership over the process – you tell us how you want to run this.

All experience levels are welcome: https://app.dover.com/apply/98147191-8319-43cd-911f-98f678be...
