Happy Returns (a UPS company) is building the systems behind fast, easy online returns and exchanges for major retailers and millions of shoppers.
We’re hiring an entry-level full-stack Software Engineer (1–3 years) to ship features end-to-end across APIs + web apps, participate in design reviews, and help keep systems reliable and performant.
Stack: Go, TypeScript, React, PostgreSQL (plus some AWS/Kubernetes/Docker; DynamoDB familiarity is a bonus)
You’ll do: E2E project ownership; REST API + UI work, code reviews, testing/monitoring/debugging, collaborate closely with Product/DevOps/QA, and use AI-assisted dev tools in your workflow.
Notes: No visa sponsorship/transfer.
BetterDB is building the tooling ecosystem for Valkey, the high-performance Redis fork backed by AWS, Google, and Oracle. We're starting with observability — historical persistence, pattern analysis, anomaly detection, and Prometheus export — so you can debug what happened at 3am when you wake up at 9am.
Stack: TypeScript, NestJS + Fastify, React, Valkey, PostgreSQL, Docker, Kubernetes, Terraform, AWS.
We ship OSS self-hosted and are launching a cloud SaaS.
We're building in public — open-source core, open roadmap, and transparent about what we're learning along the way. Looking for a senior/founding engineer as first hire. You'll shape the product and architecture alongside the founder (ex-Redis, backed by Open Core Ventures). To apply, email kristiyan@betterdb.com with:
A bit about yourself and why this is interesting to you Run BetterDB with BETTERDB_LICENSE_KEY=your@email.address
docker pull betterdb/monitor docker run -d \ --name betterdb \ -p 3001:3001 \ -e DB_HOST=your-valkey-host \ -e DB_PORT=6379 \ -e BETTERDB_LICENSE_KEY=your@email.address \ betterdb/monitor:latest
(Yes, this filters out bots. And you get to see what you'd be working on.)
Lift AI builds software for the elevator industry, where paper inspection reports and faxed maintenance tickets are still normal. Almost no one is building software for this market. We manage ~5,000 properties and have 1,000+ IoT deployments on elevators across the US. The platform handles asset management, maintenance workflows, contract tracking, and an AI pipeline that extracts structured data from elevator industry documents. Django/PostgreSQL backend, React/TypeScript frontend, all on AWS. The CEO's family has been in the elevator industry for 40 years — we're not outsiders guessing at what the market needs.
You'd be our third engineer. The team is me (CTO, I write code daily, Central Time), one engineer who's been here two years and knows the domain well, and our Chief of Product who handles the PM side. No QA team, no DevOps. You own what you build.
First project: we acquired a field maintenance product that currently runs on Firebase/Firestore. You'd design the migration of its backend onto our Django/PostgreSQL stack, including figuring out a replacement for Firestore's offline sync (we're looking at ElectricSQL). You define the API contract, our other engineer builds the frontend against it. Beyond that, we're actively building AI features. One example: an invoice dispute agent that communicates directly with service providers. You'd help architect those.
Stack: Django 5 / DRF, PostgreSQL, Redis, Django Q, React Router v7, TypeScript, MUI, AWS (CDK, ECS Fargate, ElastiCache, RDS), GitHub Actions. AI features use Claude, OpenAI, and LangChain.
We're async but not siloed — Slack, GitHub PRs, and Linear are where most collaboration happens, with the occasional video call. No standups. We follow Shape Up with 4-week cycles. I review architecture proposals for your first ~90 days, then you own your domains. No on-call rotation. We don't do evening releases, and when something rare breaks, everyone pitches in.
$100K base + 0.50–0.75% equity. We have ~5,000 customers and growing revenue, so the equity isn't a lottery ticket. $100K is below big-city market rate and we know that. We're not focused on titles or hierarchy. Growth here means the scope of what you own keeps expanding, and comp grows with it.
5+ years experience. Python (Django, Flask, or FastAPI) and React/TypeScript in production. You've built something from architecture to deployment without someone telling you how. If you've been engineer #2-5 at a startup, or you're a senior engineer tired of process overhead, or you're at an agency and want to go deep on one product, this is that kind of role.
hiring@liftai.com — send something you've built that you're proud of, and tell us why.

Cliniko is made up of a team of 63 considerate and friendly people, spread around the world. We work completely remotely, although our base is in Melbourne, Australia. We care much more about finding the best person for the job, rather than looking for someone that lives nearby.

We're focused on making great software and providing great support. We take pride in doing our best work, and enjoy bettering ourselves and each other. We strive to make the world a bit better, both personally and through our work.

I’m hiring a cracked Founding Growth Engineer to build virality directly into the product and drive 100x user growth.

Stack: TypeScript, React, Next.js, Tailwind, React Native | Node.js, Prisma, PostgreSQL
The work: You'll ship pixel-perfect UIs from Figma designs, make architectural decisions, and see your code go into production for real clients. No legacy maintenance, just greenfield builds.
Strictly on-site (Mon-Fri, 9-5:30pm) because we believe in high-bandwidth collaboration. No remote.
Outside of client work, we also incubate internal SaaS products. Team members can contribute to these projects outside regular hours for equity if interested.

Flutter/Shorebird founder here. Flutter is used by millions of devs (and nearly ⅓ of free apps submitted to AppStore), but is missing services for businesses. We offer Flutter-related SAAS used by 1000s businesses globally, on track to profitability mid 2026.
We serve 100s of millions of devices from our cloud, (2k+ RPS sustained), built mostly in Dart on Google Cloud + CloudFlare. We’re in the process of launching a series of CI offerings and have a lot of cloud development work ahead of us. You need production cloud experience, want to work at a startup, and be up for the challenge of owning, developing, and expanding Shorebird’s cloud infrastructure and backend services including code, configuration, architecture, and more. Previous Dart experience is not required.
We’re a small, senior team, making something people want. Tech: GCP, Cloudflare, Dart, Postgres, a little React & Node. Shorebird operates almost entirely in the public over Discord. https://discord.gg/shorebird
I’m Scott - founder of DoStuff. We have a pretty big, and growing, membership product called DoMORE - $7/month for a pair of tickets to an event we think you’ll like. We’re hiring a hands-on Retention Product Engineer to own engagement → churn reduction end-to-end.
You will analyze cohorts, define the retention north-star metric, ship product and lifecycle experiments yourself, and measure impact.
This is not a PM-only role and not a pure engineering role. You own the full loop: insight → build → measure → iterate.
Our stack: React (FE), Ruby on Rails + Elixir (BE), Postgres, Elasticsearch. Proprietary lifecycle tooling for email, SMS, and in-app (web). No feature-flagging or experimentation framework yet - you’ll help install the remaining plumbing.
Retention is the highest-impact opportunity in the business and this role has real authority to ship.
If you have experience with the above and this sounds like fun, reach out to scott+domore@dostuffmedia.com with something in the subject line that let’s me know you’re real and interested. THX

We’re building the biggest second-hand bike shop in the world.
Upway is the leading marketplace for refurbished e-bikes across Europe and the United States.
In 3 years, we grew from 0 to $200M GMV. The tech team grew from a small senior core to ~12 engineers in 2025, and we plan to grow to ~30 engineers in 2026. We also raised a $60M Series C at the end of last year to support the next phase of the company.
This is not a SaaS. We operate warehouses, handle real inventory, and build software that connects logistics, product, and marketplace dynamics at scale.
We’re looking for engineers and product people who like tech as much as business, people who want ownership, enjoy making product and business trade-offs, and care about outcomes, not just systems.
We work with a Shape Up–inspired methodology that gives teams real ownership: shaping problems, building solutions, shipping, and learning from real-world impact.
Stack: TypeScript | NestJS | React | Shopify | PostgreSQL | GCP
Why it’s a great time to join:
- The organization is switching gears: bigger ambitions, broader scope, more responsibility.
- The challenges are growing with the team: product, marketplace, and operational complexity.
- High ownership environment where engineers influence technical and business decisions.
- Paris on purpose: at our current pace, working in person is a real advantage.

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

• Senior Software Engineer, Customer Engineering ($150–200K) — if you like to hear a customer request in the morning and tell them it’s shipped in the afternoon. US and Canada only for this one
• Senior Software Engineer, Growth ($150–200K) — be the engineer who has the most direct impact on our growth
• Data Analyst ($80–140K) — build models to help power decision-making across our business (not a dev role but thought I'd include it)
We're looking for people who have great startup energy, want to win, and bring great vibes to our tight-knit team. Great time to join since our offsite in London is happening soon (we're US-based, this is our third international offsite).
