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.

This is explicitly an insurance role: keep the platform reliable, no major evolution or greenfield work. The platform has run reliably for years (no critical outages unrelated to deploys/changes in 5+ years) — we want someone to keep it that way.

Engagement: ~4h/week retainer paid on-call for critical incidents planned/larger tasks quoted separately fully remote, EU/CET, reachable during Spanish business hours

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

Work: monitoring, alert triage, routine maintenance, incident response, certificates/security updates, and infrastructure decision-support. No application development or architecture ownership expected.

Stack: AWS Elastic Beanstalk, ECS, Lambda, RDS, ElastiCache, Redshift, S3, SQS, CloudFront, WAF, Route 53, IAM, CloudWatch; MongoDB Atlas, Elastic Cloud, n8n, Metabase, Sentry, Bitbucket Pipelines.

Looking for someone senior who can handle incidents independently and is comfortable with a stable-platform maintenance/on-call role.

Steel | Applied AI Engineer + Infrastructure Engineer | Toronto, ON | ONSITE | $160k-$240k USD base + equity

Steel is open-source browser infrastructure for AI agents and apps. We make it easy for developers to ship products that interact with the web - without spending 80% of their time on browser pools, proxies, CAPTCHAs, and session state. In 2025 we grew 50x: 6,000+ GitHub stars, dozens of paying customers, millions of sessions served monthly. Dedicated chromium runs on Firecracker VMs for sub-second cold starts.

Stack: TypeScript, React/Next.js, Node.js, AWS, Firecracker, Postgres, Redis. 4+ YOE for both roles.

--- Applied AI Engineer ---

Shape how AI agents interact with the web. Build open-source frameworks/demos on the Sessions API, run experiments on which models/prompts/harnesses actually work, build evals against real scenarios, and work with customers shipping agents to production. AI-native full-stack engineers with strong product sense.

--- Infrastructure Engineer ---

Design and operate the systems Steel runs on. Sample projects: VM snapshotting that restores full browser state in under a second, performance-tuning the Sessions API from kernel traces, orchestrating millions of sessions with sub-second cold starts. Distributed-systems experience, strong AWS/GCP and Linux/OS fundamentals. Rust is a plus.

Public referral bonus: $10,000 if your intro becomes a hire.

Apply: email careers@steel.dev with GitHub & resume, mention HN.

Elucid | Principal Platform Engineer | Boston, MA | ONSITE (hybrid) | $170k–$205k | https://elucid.applytojob.com/apply/BHpChxSggM/Principal-Pla...

Elucid builds FDA-cleared AI software that analyzes cardiac CT scans to characterize plaque and predict heart attack and stroke risk. The world's best cardiologists use our output to make treatment decisions for real patients. As such, our platform is regulated as a Software as a Medical Device (SaMD) product by the FDA and we operate under HIPAA, ISO 13485, and ISO 27001.

We're hiring a Principal Platform Engineer to own our cloud infrastructure and developer platform: AWS, containers, Terraform, CI/CD, observability, and the self-service tooling that lets our application teams ship quickly inside a regulated SDLC.

We are looking for: 7+ years in DevOps/SRE/platform roles, deep AWS, strong IaC, comfort with containers (ECS/Fargate, Kubernetes), and one language you reach for when building tooling (Python, Go, Rust, Ruby, C++). Healthcare or regulated-industry experience is a plus, but not a requirement.

On-call is a shared rotation, roughly 2–3 weeks per quarter, business-day coverage only (9am–midnight ET, no overnights).

Apply at the link above.

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*:

Founding Product Engineer / Systems Architect You will own the Django backend, MongoDB schemas, and the Flutter UI that connects them. Our AI pipeline lead handles the Gemini orchestration — your job is to own the data layer, build the API surface, and wire it directly into the offline-first client. This is not drawing backend diagrams. You must be an end-to-end builder who cares about how a civilian interacts with the system on the ground in a crisis. A bug in this system isn't a 500 error — it's a missed warning in a conflict zone.

   *Must have*:

Python/Django, MongoDB, Flutter (or high competence to pick it up fast), and system design thinking. Strong plus: DevOps (Docker, AWS), LLM integration, OSINT, geospatial.

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

   *Compensation (No BS)*:

- Now: Sweat equity (12-18% SA / 5-10% FSD, 4yr vest, 1yr cliff). This is founding-team ownership. - Pre-Seed (closing): $3,000/month + equity.

- 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.

   *Stack*: 

Python 3.9+, Django 4.1.13, MongoDB, Flutter, Antigravity/Cursor IDE, Docker, AWS.

   *Apply*:

Brandfetch (https://brandfetch.com) | Senior Backend Engineer | Remote | Full-time

Brandfetch is the internet’s canonical source for logos and brand assets. Think GitHub for brand identity: a brand repo that auto-indexes public assets, lets brand owners “commit” changes once, then propagates them—instantly and immutably—through CDNs, plugins, and APIs used by companies like Google, Canva, Salesforce, and soon … everywhere.

Problems you'd work on:

- Nightly curation bot auto-fixing outdated assets across 52M+ repos

- 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.

- Great communication skills (we work across multiple timezones and document everything).

- Experience with Machine Learning.

Competitive salary + equity in a profitable, growing company.

*Labor Solutions (YC-style) | Senior Software Engineer | Remote (India) | Full-time*

We run a worker wellbeing and compliance platform used by global buyers and their supply chain sites across Asia. We're in the middle of a meaningful migration and platform buildout — you'd be joining at a point where architectural decisions matter and your fingerprints will be on the system for years.

*The work:* Our stack is Django + Python on the backend, dbt for data transformation, React/Next.js on web, and Expo/React Native for mobile. We run on AWS and Azure. Right now we're migrating legacy services while simultaneously shipping new features — so you'll need to be comfortable holding both in your head.

*What we're looking for:*

- Strong Python/Django chops — you've built and maintained production APIs, not just tutorials - Comfortable with React/Next.js; bonus if you've touched Expo or React Native - You understand what a data pipeline actually does (dbt experience a plus, but SQL fluency matters more) - Cloud experience on AWS or Azure — not ops, but enough to not be blocked - You care about code quality without being precious about it

*What this isn't:* This isn't a greenfield startup with infinite runway. It's a real product with real users, real technical debt, and a migration in progress. If that sounds like a problem, this role isn't for you. If that sounds like the most interesting kind of work, let's talk.

*Details:* - Fully remote, India-based - Senior Software Engineer title

Stream | Amsterdam (NL), Skopje (North Macedonia)| Remote possible | Full Time | Visa Sponsorship

We power real-time Chat, Video, Activity Feeds, and AI Moderation for apps like Strava, Bumble, eBay, and Patreon - billions of API requests per month, millions of concurrent users.

We're looking for a hands-on Lead Engineer (Staff / Principal level) to own Platform & Infrastructure.

Reports directly to the CTO.

Small, senior team - you'll write code most of the time, not run a process org. First 6 months focus on three things with measurable outcomes:

* Cloud cost optimization (AWS/GCP) — tooling and guardrails, not reports

* Platform reliability and scalability — SLOs, observability, hardening

* Architecture decisions on Kubernetes, databases, and cloud provider strategy

Stack: Go, Python, AWS, GCP, Kubernetes, PostgreSQL, CockroachDB, Redis, Terraform.

Looking for: software engineering background (Go or Python, not scripting-only), production cloud cost optimization experience, real distributed systems depth, and active AI tooling use in your engineering workflow.

Not a fit if: you're security/compliance-heavy, scripting-only, or dependent on large-org support structures.
