You'll help lead large frontend initiatives, define architecture, mentor engineers, and work closely with Product and Backend teams.

Tech: React 19, Next.js 16 (App Router), TypeScript, Tailwind, shadcn/ui, Playwright, Datadog, Node.js, Ruby on Rails, PostgreSQL, MongoDB, AWS.

Looking for engineers with 6-10 years of experience building production web applications and deep expertise in React/Next.js.

Double Holo | Founding Mobile Engineer | Chattanooga, TN | ONSITE | $120k-150k | https://doubleholo.com

Double Holo is the modern marketplace & intelligence platform for trading cards.

New grads welcome to apply.

You will own the React Native app end to end: architecture, releases, performance, and parity with a web product that ships daily.

This is a founding engineer role at a high-growth startup. The hours are long, the surface area is huge, and the ownership is real. If you want scoped tickets and a roadmap handed to you, this is the wrong job. If you want to build the app an entire hobby checks before breakfast, keep reading.

In person preferred but remote may be permitted for the right candidate.

Our website and mobile apps are already live.

Trinsic | Senior Product Engineer | REMOTE (Europe) | Full-time

We're building the first Identity Acceptance Network, the "Visa for ID." Humanity is editing genes, starting space tourism, and verging on artificial general intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards.

Role - Senior Product Engineer (#5 on the team; ~20% of engineering capacity). High ownership, product-minded, backend and systems leaning. - This is not a ticket-churning role. You should want to understand the competitive landscape, listen in on customer calls, bring engineering insight to product discussions, and own features end-to-end. - You should be a Barrel: someone who can take on ambiguous work, pull together the right context, make tradeoffs explicit, and drive without needing to be told every next step. Revenue is surging, we need judgement to help shape the product. - Strong backend/platform experience; generalist enough to move up/down the stack when the product needs it. - You care deeply about user privacy and data security. We work on identity. Sloppiness here is not an option.

Stack & ways of working - .NET (C#) backend, React + TypeScript frontend, Azure Container Apps, Azure SQL/Storage, Bicep IaC, GitHub CI/CD. - Remote-first; North America (CT +/- 2) or Europe (CET +/- 1). Strong async work habits; 4 hrs/week of scheduled meetings on average; pairing/huddles when useful. - We use AI aggressively and prudently. You'll have a large token budget, but we expect strong judgment around the risks.

Comp & apply

- Salary is set by our compensation philosophy, with meaningful equity. We discuss compensation early so neither side wastes time.

- Apply: https://www.trinsic.id/careers/senior-product-engineer?utm_s...

If you're in a workable timezone and excited about identity infrastructure, I'd love to talk.

OpsMill | Principal Software Engineer & Product Reliability Engineer | Europe/US | REMOTE | Full-time

OpsMill builds Infrahub, an open-source infra source of truth. Network and infra teams use it to manage their data and automate at scale.

Principal Software Engineer — own the architecture across our platform. Shape the graph database engine and backend, cut tech debt, push AI-first engineering. Need: 10+ years backend/platform, expert Python, track record scaling distributed systems.

Product Reliability Engineer — customers run us on-prem, so reliability is the product. You'll dig into Kubernetes escalations, find root causes, build tooling so issues don't come back. Need: 4-7 years SRE/production engineering, solid Kubernetes debugging, Python/Go/Rust. Remote. Apply:

Principal SWE: https://jobs.ashbyhq.com/opsmill/f7ef59f0-e2bb-43db-a450-c4e... Reliability Eng: https://jobs.ashbyhq.com/opsmill/b4af4790-46fd-430d-96bf-d45...

I'm Dimitris Saltaferis, Head of Engineering at OpsMill.

Ditto | Engineering & Product | Remote (US: Atlanta, Austin, SF, Seattle) + APAC | Full-time https://jobs.ashbyhq.com/ditto

I've been obsessed with CRDTs since I first saw them at Strange Loop years ago, and I still can't quite believe I now get to work on them for a living — in some of the most challenging environments there are: disconnected, degraded, contested, out where the cloud isn't. If that's your kind of problem, come build with us.

Ditto is the edge-native data platform that keeps distributed systems in sync when the network doesn't cooperate — an offline-first, CRDT-based layer syncing any device (phone, vehicle, sensor, server) over Bluetooth LE, P2P Wi-Fi, LAN, and tactical radio, with or without connectivity. Same core, commercial to defense; operationally deployed and network-agnostic. The problems are the fun kind: conflict-free replication with no server and no synchronized clock, multi-transport routing that never drops the connection, moving a coherent picture over links as thin as an HF radio shot, and human-in-the-loop robotics/autonomy where a detection may have to be physically carried by a moving node. Concept to field in days, not months.

Most roles are open to anyone authorized to work in the U.S.; Public Sector and forward-deployed roles require U.S. person status. Remote in the U.S. (hubs: Atlanta, Austin, SF, Seattle) unless noted.

Product — Senior PM: Cloud Database & Integrations; Cloud Infrastructure & Platform

Engineering — Engineering Manager, Data Sync

Public Sector (U.S. persons) — Senior SWE: Autonomy · Systems FDE · Portal (ATL/remote) · FDE (SF, on-site); SWE, Public Sector Application
