Always Further, founded by team who created https://sigstore.dev , used to secure npm, pypi, brew, and provide attestations for github releases, nvidia and google for AI model signing - we and are now building https://nono.sh agent security tooling.

We have roles open for a principal software engineer:

We're looking for a Principal Software Engineer to join as a founding engineer. You'll work directly with the founders to build the core of our agent security runtime. This is a high-autonomy role - you'll shape architecture, engage with early customers, and make the trade-offs that define the product.

You will build the layer between agentic reasoning and system execution — intercepting, classifying, and validating every agent intent against security policy before it runs. Design systems that capture and cryptographically verify every instruction and action, maintaining ground truth in environments prone to hallucination and injection. Architect fine-grained, time-scoped primitives that allow least-privilege permissions, with the ability to escalate under controlled, auditable conditions. Work with research to stress-test our security primitives at scale. Turn emerging threat vectors (prompt injection, tool misuse, privilege escalation) into adaptive defences.

Staff solutions engineer:

We're looking for a Solutions Engineer join as a founding engineer and to sit at the intersection of our open source community and our growing base of enterprise design partners. You'll spend your time contributing to Nono, helping shape its architecture, and working directly with customers who are integrating it into proof-of-concept and pilot programmes. This is a hands-on role - early on you'll be deep in the code, reviewing pull requests, triaging issues, and experimenting with deployment architectures, all while being a trusted technical voice for both community members and enterprise stakeholders. Over time, the role will evolve toward solutions architecture and customer-facing engagement, as you build the domain expertise and relationships that make you the go-to person for designing how Nono fits into complex enterprise environments.

What You'll Do" Contribute directly to the Nono open source project - code, documentation, and architectural proposals. Experiment with different deployment architectures for Nono across cloud environments, on-premise infrastructure, and hybrid setups and share your findings with others at Always Further, and often with the community, via our blogging platforms or YouTube channel. Work closely with early design partners to integrate Nono into proof-of-concept and pilot programmes, gathering feedback and translating it into engineering priorities. Produce technical content - blog posts, architecture guides, demos.

MintMCP | Founding Engineer / Founding GTM | SF Bay Area (ONSITE)

MintMCP helps enterprises safely do more with Agents (e.g, governance around MCP tools and agents like Claude Code / Cowork, and others). We're building an MCP gateway as the foundation with the proper abstractions that enterprises need to allow long running agents to be safely deployed across an entire organization; organizations can easily and clearly limit the blast radius of what an agent can do, while giving it the right combination of tools to be useful.

We're a small team of humans with dozens of agents: our company operates on the infrastructure we build for enterprises. We're looking for agent-forward engineers and GTM folks to help solve scaling problems, maintain the highest standards for security, make agents and MCPs usable and useful.

Problems we're solving right now: Agent Identity, ReBaC for tool resources, scalable hosting of private MCP servers, and our agent platform that vertically integrates with the foundational MCP gateway layer.

If you have experience in infra, security, and agents, and MCPs, you might find the problems we're working on exciting!

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, Vertex AI (Gemini 3 Pro Preview / 2.5 Flash / 3 Flash Preview), Docker, AWS.

*Apply:* Email PeterJFrancoIII@gmail.com with subject line `[SENTINEL-BUILDER] - HackerNews Application`. To prove you read this, include the word "Atlas" in your first sentence. Include your Resume or GitHub + what you'd build in your first week. (Emails without the exact subject line are auto-archived.)
