Instinct Science | Senior Full-Stack Engineer (Elixir + React) | REMOTE (US)

Instinct Science is the AI leader in veterinary medicine. We build the platform that powers animal hospitals — a cloud-native EMR with real-time clinical decision support and applied AI that helps veterinary teams practice at their best. Thousands of users across the globe rely on what we ship every day.

We're at an inflection point: proven product-market fit, scaling fast, and greenfield work ahead that will serve tens of thousands of users. Engineers here own problems end-to-end — from talking to veterinarians about their biggest frustrations, to shipping production code, to iterating on real feedback. You're measured by customer impact, not story points.

WHAT YOU'LL DO: - Drive product direction alongside customers and PMs — not just implement specs - Design scalable, elegant solutions in Elixir and React - Ship meaningful updates weekly, gather feedback, and iterate - Mentor junior engineers and define patterns that scale with the team

WHAT WE'RE LOOKING FOR: Must-haves: - 5+ years building modern SaaS applications, full-stack - Ability to break complex problems into efficient, actionable work - Team-first attitude; strong communication in a remote environment - Empathy for customers — you care about what ships and who uses it

Nice-to-haves: - Elixir or Erlang (we love functional programming) - TypeScript and React - AWS (build, deploy, troubleshoot) - Relational database design and query tuning

STACK: Elixir, React, TypeScript, PostgreSQL, AWS

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.

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...

Deepline | NYC (ONSITE) | Founding Full-stack Engineers and Forward Deployed Engineers | $160k–$230k + meaningful equity

User interfaces are dead. Knowledge workers will exclusively work through agent interfaces like Claude Code/Cowork. We've built the interface layer to enable that.

One API that unifies hundreds of data providers, workflows, and data infrastructure to agents like Claude Code. This is GTM as code — Stripe is to financial infrastructure what Deepline is to GTM infrastructure. Hundreds of users signing up weekly / +50% growth each month since Feb.

You'd build core platform: agent-facing abstractions, infrastructure, UI. TypeScript/Python/Next.js/Postgres. $3.3M raised from Lerer Hippeau + Looker founding team. Technical founding team from Uber, Lyft, Capchase, MIT, Waterloo.

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. You'll partner directly with Engineering, Finance, and Operations to fix data quality at the source, not downstream.

Tech stack: SQL, dbt, Redshift, Postgres, Looker (+ LookML), Fivetran, Airflow, Salesforce

We're looking for 5+ years in analytics/data engineering, deep hands-on dbt experience, strong SQL, and a track record of turning messy datasets into a trusted single source of truth. Bonus points for retention/lifecycle modeling, Looker administration, prepping datasets for AI consumption, or Medicare/insurance experience.

This is a hybrid position in our new Boston office near South Station, so local candidates only please. Unfortunately we are unable to do visa sponsorships at this time. Apply: https://recruiting.paylocity.com/recruiting/jobs/Details/422...

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.

ALBERT | REMOTE ALMOST ANYWHERE IN THE WORLD| Hiring principal and distinguished engineers to build net new products | up to ~ $750k cash hiring plus meaningful equity: exceptional consumer product engineers at Albert.

We're a consumer fintech with 20M+ users who trust us to budget, save, invest, and bank in one place. Profitable for 4+ years. And as of today, our average employee tenure is 3.6 years, a number you almost never see in startup tech, and one we're quietly proud of. People stay because the work is good, the people are sharp, and we've built something worth staying for.

Now we're building net-new consumer products from zero, and we're looking for people who love to tinker and build stuff to ship them with us.

The kind of person we're looking for: • Top fraction of a percentile in craft, the kind of good that's hard to fake • Builds for fun, not just for work. The kind who ships a working prototype over the weekend and can't help themselves • Comfortable owning 0 to 1 consumer products end-to-end • Allergic to politics, theater, and bureaucracy

What you get: • Remote, anywhere with reasonable timezone overlap (and for someone truly exceptional, we'll make async work) • Real scale from day one (20M+ users, real money, real consequences) • Compensation that beats the market. We pay well and we mean it. Base, discretionary year-end bonus, meaningful 401(k) match, and meaningful equity in a profitable, growing unicorn (the kind that's actually worth something) • Platinum PPO health benefits with Blue Shield, top of the top of the line, covering your entire family • A mission worth your time: make money simple, so people spend less time managing it and keep more of it • Small senior-heavy teams, direct ownership, no layers • Forthcoming with the business metrics that matter, so you always know how the company is actually doing • The startup perks done right: catered lunches, wellness stipend, team offsites, casual dress. The stuff that compounds when you're showing up engaged for years, not months • Profitable for 4+ years, so you build with conviction, not runway anxiety

Stack: python, claude, postgres, react.js /react native

If this is you, email us at recruiting@albert.com

Edit: we are in the process of rebuilding our career site to speak to how we hire (e.g. hunt, dont post, find the best). Just an FYI

Also, we carefully review every application. If we think there may be a fit, we'll reach out within a few business days. Either way, thank you for your interest in what we're building and for taking the time to connect with us.
