HelpMyCash | Senior AWS DevOps/SRE contractor | Remote EU/CET | Freelance + paid on-call

HelpMyCash is a Barcelona-based financial comparison platform. We're looking for a senior freelance DevOps/SRE to act as the operational safety net for a mature AWS production platform.

Compensation: retainer + hourly rate + on-call premium for out-of-hours response. Exact structure and rates open to discussion based on your model.

HME Technologies | AI Operations Lead | REMOTE | Full-Time | $40k-$75k base + Bonus

HME Technologies (https://hmetech.com/) is a small, profitable media and affiliate marketing company. We build audiences, sell sponsorships, and run a growing portfolio of content properties across YouTube and emerging platforms. We're operator-run, AI-native, and looking for our first AI Operations Lead to work directly with the co-founder to turn our AI capabilities into a serious operational advantage.

What you will do:

> Build the short-form engine: Design and run an AI-leveraged workflow to repurpose years of long-form content into 50-100 pieces/week for TikTok, Reels, and Shorts.

> Stand up owned analytics: Move us off spreadsheets and partner dashboards. Build clear tracking for email growth, content performance, and affiliate attribution.

> Be the AI execution engine: Build automations (Make, Zapier, n8n) and write Python or JavaScript when needed to glue systems together.

> Operationalize AI internally: Build practical AI workflows for our creative directors, salespeople, and content producers to speed up their output.

What we are looking for:

- You ship: You aren't just "AI-curious"—you use Claude, ChatGPT, and automation tools to do real work every week.

- You operate: You can take a directive like "we need a thing that does X" and come back with a finished system, making the small decisions along the way.

- You write: We work async. We use Slack, Notion, and Google Docs. If your default is to schedule a meeting, this is the wrong role.

Our culture: Async-first, zero bureaucracy, and a sustainable pace. We don't do crunch culture, we respect off-hours, and we completely pause work for Shabbat (Friday sundown to Saturday night). Sustained operators need sustained rest.

How to apply:

Fill out our application form here: https: https://tally.so/r/b5Nbe1

Full JD: https://docs.google.com/document/d/1dP5-nrLAaGIMzkCSSdLyj78F...

Please do not send a resume. If we're interested, you will do a paid project (4-8 hours of work, solving a real problem we have). We pay you for your time whether we hire you or not. If it's a fit, we move fast.

Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed Closing

   We build real-time civilian threat intelligence for conflict zones — and we just landed our first operational pilot. Multi-model AI pipeline (Gemini 3 Pro / Flash) ingests OSINT from verified sources, runs it through a gated verification system, and pushes geolocated alerts to offline-first mobile clients. Think of it as a personal intelligence analyst for non-combatants — on a phone that works on 2G.

   This is not a pitch deck. We have a working system: Django backend is live, Flutter apps are approved on both App Store and Play Store, multi-gate AI pipeline is processing real OSINT, admin console has human-in-the-loop verification for high-severity alerts. Since our last HN post: 93 candidates vetted across two months, 1 Senior AI/Backend Engineer hired (now owns the verification pipeline), and we've begun an operational pilot with Winrock International for counter-trafficking intelligence in Southeast Asia. Pre-seed is imminent with multiple NGO grant applications under review (WFP, IRC Airbel, DRK Foundation).

   *We need one person*:

   *Must have*:

We also welcome strong full-stack implementation engineers who ship fast and want founding-team equity. Same stack.

   *Compensation (No BS)*:

- Seed (6-12 months): 75% market salary + equity. Increases from there.

If you need full salary today, this is not for you. If you want to build something where the stakes are real and you're willing to bet on yourself to get there — we should talk.

Brandfetch is the internet’s canonical source for logos and brand assets.

- Next-gen ingestion and partition-key schema to leap from millions to billions of assets

- MCP server that exposes structured brand data to any AI agent or LLM, letting them fetch brand context on demand

- Vector search: surface any logo with ≥90% similarity in <50ms

- Real-time metering that pings Stripe the instant a user tops their quota

Stack: Node.js, TypeScript, Python, AWS (Lambda, DynamoDB, CloudFront, S3, CloudFormation), Serverless.

You:

- 8+ years of experience in backend software development.

- Proficiency with AWS tools (Cloudformation, API Gateway, DynamoDB, Lambda, Cloudfront, S3, IAM, OpenSearch).

- Experience with building REST APIs.

- Ability to write well-documented, clean code.

- Experience with building DevOps pipelines using Serverless.

- Experience with Machine Learning.

Competitive salary + equity in a profitable, growing company.
