Founder Ventures (Rankwise, Debriefing, OutFriend) | Head of Growth and CEO roles | REMOTE (Europe/US friendly) | Equity-led

Founder Ventures is a venture studio building bootstrapped B2B SaaS. Three of our companies are hiring the person who will own their commercial side outright, working alongside a technical founder who ships daily. These are founder seats with an equity-led package. We say that up front because it is the first thing worth knowing.

Rankwise | Head of Growth | https://tryrankwise.com The infrastructure layer for AI search. Measures whether AI engines cite you, finds the questions they answer without mentioning you, then drafts the articles and ships the live-site technical fixes that close the gap. Live and self-serve. Own acquisition, conversion and retention end to end. Apply: jan@tryrankwise.com JD: https://founderventures.io/careers/rankwise-head-of-growth

Debriefing | CEO | https://debriefing.io Competitive and market intelligence as a recurring brief. A displacement play against sales-led incumbents charging $15K-$50K+ a year, at $2K-$4K, AI-native and product-led. Live product, technical founder in place, the commercial side entirely yours to own. Apply: team@debriefing.io JD: https://founderventures.io/careers/debriefing-ceo

OutFriend | CEO | https://outfriend.com Cold email that sounds like you. Learns a sender's voice from their own past emails, runs the campaign, handles follow-ups, and surfaces the replies worth answering. Built and launching, go-to-market wide open, so this is the earliest seat. Apply: stefan@outfriend.com JD: https://founderventures.io/careers/outfriend-ceo

Looking for people who have run growth or revenue at a B2B SaaS, done it at early stage, can sell personally, and think quantitatively. PLG experience matters more than headcount managed.

Symbolic.ai | Senior Fullstack Engineer | REMOTE (worldwide) | Full-time

Symbolic builds the AI platform that professional newsrooms and communications teams actually run their work on: research, drafting, fact-checking, and publishing, with editorial integrity as the constraint rather than an afterthought. Founded in 2023 by Devin Wenig (former eBay CEO) and Jon Stokes (Ars Technica co-founder), ~$12M raised, small team. Clients include News Corp, WSJ, Dow Jones Newswires.

We are looking to expand the venn diagram of our fullstack team in the direction of very advanced React expertise. While this is a fullstack position, we are seeking someone who has worked on the frontend of complex real-time collaboration products built in React.

Email me: gilles@symbolic.ai. Tell me about the most complex thing you built in React.

Cologne, Germany | UMH | Product Engineer | Full-time | 55 - 85k EUR | ONSITE (part remote)

Hi, Alex and Jeremy here from UMH.

8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.

What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.

Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.

PermitFlow (YC W22) | Staff, Fullstack & Frontend Software Engineers | New York, NY | ONSITE | Full-time | https://permitflow.com PermitFlow’s mission is to streamline and simplify construction permitting in the $1.6 trillion United States construction market. Our software reduces time to permit, supporting permitting end-to-end including permit research, application preparation, submission, and monitoring.

We recently raised a $54M Series B led by Accel with participation from Kleiner Perkins, Felicis, Altos Ventures, and YC.

Permitting is a challenging yet interesting problem; thousands of municipalities across the United States have their own processes and requirements - many which are continually updating. Software, AI, and LLMs provide an exciting opportunity for us to reason at scale and distill a nuanced and localized permitting process into a standard and streamlined experience for our customers.

We're looking for customer-obsessed, ambitious, and hard-working teammates who are excited about solving a real-world problem with technology at its helm.

NYC Onsite Roles | apply at: https://jobs.ashbyhq.com/permitflow?departmentId=d33195eb-89...

1. Staff Software Engineer - $200K-275K + equity

2. Fullstack Software Engineer - $125-245K + equity

3. Senior Frontend Engineer - $125K-245K + equity

Vitabyte | Full-Stack Engineer | Astoria, NYC | ONSITE | Full-time | $110k–$130k

We build payment and point-of-sale software for restaurants, bars, and nightclubs, mostly on Oracle MICROS Simphony (we're an Oracle partner). Small team, real money moving in production — you own systems, not tickets.

Stack: Go (Echo, GORM, Postgres) for the payments API and the Oracle SPI/OPI service; Next.js / React / TypeScript for the operator portal; Kotlin / Jetpack Compose for the Android card-terminal app.

Looking for ~3–6 yrs, strong in Go or TypeScript and happy to learn the rest. You care about correctness (a double-charge isn't a cosmetic bug) and can read an existing codebase. Payments/Simphony experience is a plus, but we'll teach it.

Apply: email george@vitabyte.com with something you've built and shipped — what it did and what was hard.

Dave Evans | Founding Engineer | Remote | Full-time | $170k-$210k + meaningful equity

I’m hiring the first senior engineering hire for an early-stage multi-agent product.

This is for a senior backend/platform builder who still likes shipping product, not just designing systems. The work is a mix of orchestration, integrations, reliability, auditability, and getting useful workflow automation into users’ hands quickly.

You’d work directly with me to turn a strong technical direction into a dependable product.

Best fit: 6+ years shipping end-to-end, strong backend judgement, product range, low-ceremony style, and comfort with ambiguity.

Helpful if you care about retries, tool boundaries, observability, and human override in AI systems.

Comp is in the $170k-$210k base range with meaningful equity.

If that sounds like your lane, email dave@evanlee.co.uk with a short note and links to shipped work.

There is a massive competitive advantage right now in building 'boring' infrastructure manually instead of rushing to wrap an AI API.

While the trend is to build a conversational interface for everything, I've found that real businesses are still bleeding time on core sales friction. For example, moving away from static PDFs to interactive live sales quotations requires rock-solid, hand-coded database architecture to handle real-time pricing, currency locking, and instant approvals. You simply can't prompt an LLM to reliably handle that level of strict state management.

Taking the time to write the core logic yourself makes the system predictable. Businesses don't pay for the AI novelty; they pay for seamless operational execution

ResortPass | Senior Software Engineer, Frontend | New York, NY | Full-time, In-Office | $160K-$180K + equity | resortpass.com

We're rewriting resortpass.com — starting with our highest-traffic surfaces (SRP/DLP) — and need a Senior Frontend Engineer to be the technical anchor. ~75% of pages get touched this year: international expansion (Mexico & Caribbean now, Europe next), in-housing search from Algolia, a new Hotel SaaS tool, and Spa as a major new vertical.

Senior role, Staff-leaning scope, clear path to Tech Lead. 2/3 of traffic is web, so performance is business-critical (Core Web Vitals, SEO, caching), and this codebase is also our launchpad for AI features (concierge chatbot, AI spa booker).

Stack: Next.js 16 (App Router), React 19, TypeScript, Tailwind, shadcn/ui. Backend: Rails, Node/AWS, Postgres, MongoDB. Playwright + Datadog.

You'll own: technical design (RFCs) for major rewrites, reusable App Router patterns, code quality/mentorship for a junior-leaning team, and API contracts with backend.

Need: 6+ yrs production web apps, deep React/Next.js expertise, proven track record leading high-traffic rewrites with measurable results. Strong full-stack engineers open to leveling up on React also welcome.

Visa: not standard, possible exception for exceptional candidates. JD + Apply: https://uctalent.io/referral/Huynh_Nhu_Bao_Nhan221138/v8QmsN...

Connie Health | Senior Analytics Engineer | Boston, MA | HYBRID | $150k-$185k + equity

Connie Health is a fast-growing Medicare brokerage on a mission to empower older Americans to make confident, worry-free Medicare plan decisions. We offer a tech-enabled Medicare navigation platform that combines AI-driven technology with local Medicare experts to help people select optimal healthcare plans and navigate their benefits. Backed by leading investors such as Khosla Ventures, we are building technology to transform the trillion dollar Medicare insurance industry, impacting the lives of 67 million people in the US.

We are looking for a Senior Analytics Engineer to own our data transformation layer end-to-end. You will build the clean, well-modeled, documented datasets that the entire company relies on, spanning board-level book-of-business reporting (policy count, retention, effectuation, commissions), stakeholder self-service through Looker, and AI-driven exploration through tools like Claude. This is a high-leverage senior IC role: the quality of our analytics, forecasts, and operating decisions all depend on the foundation you build.

Statecraft | Forward Deployed Engineer (Sr/Staff) | REMOTE (US) | $160-220k + equity

At Statecraft, we are building an inorganic workforce to help keep the US Government running. Our AI workers are trained on government workflows, operate reliably and compliantly, and build their own tools and software to help achieve outcomes and digitally transform outdated processes.

America is not short on forms, policies, or good people. It is short on hours. Our public servants are overworked and understaffed. For too long, contractors and consultants have made empty promises to solve this problem. Instead, they've wasted billions in taxpayer dollars. We're changing this with an AI workforce that works around the clock and improves over time. On average, we save taxpayers 80% while helping agencies deliver on initiatives and their mission 10x faster.

We're looking for a forward deployed engineer to deliver outcomes for customers, building critical systems with national impact. You'll also be working on our core platform, extending it with new capabilities.

* This position requires U.S. citizenship and the ability to obtain/maintain a security clearance.

More details on role and perks here: https://careers.statecraft.ai/jobs/forward-deployed-engineer

FusionAuth | Principal Software Engineer, Senior Java Engineer, Account Executive, Solutions Engineer | Varies between REMOTE (in USA, also in Europe but only for the account exec position) and HYBRID/ONSITE in Denver, CO, USA, details in each job desc | Salary ranges for the Senior Java Engineer it is 170k-200k, but the Euro positions don't have them :(

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We are building the only CIAM platform built to deploy anywhere, give you total control, and scale across any modern architecture–no matter how complex.

There are a lot of companies in the auth space, but we feel like we have something special:

* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.
