Senior/Leading Software Engineer (fintech)

About the Role We’re looking for a product engineer who takes ownership of outcomes, not just assigned tasks. You’ll work across 4–5 products with different technology stacks, identify high-value problems, and carry solutions through design, implementation, testing, documentation, delivery, and operation. What You'll Do Understand our apps and the 0G stack well enough to improve the shared platform, not only one feature. Solve root causes and make durable decisions using shared systems instead of introducing band-aids or duplicated solutions. Own features end-to-end across UI, APIs, server logic, infrastructure, and deployment; do not stop at the layer you are most comfortable in. Build and improve AI-agent infrastructure, including LLM streaming, tool orchestration, sandboxed execution, and security boundaries around untrusted code. Understand wallet-based identity, signing, embedded and external wallets, and server-side authorization without conflating wallet connection with application access. Independently manage dependencies, reviews, blockers, and delivery while raising genuine product decisions and risks early. Raise the bar through meaningful tests, sharp PR reviews, and living documentation that stays true to the product. Be open to adopting new technologies, AI tools, and better working practices. Be reliable enough that when you own an area, the rest of the team can confidently focus on building and expanding other products. Treat “done” as delivered, verified, and operating—not merely coded or test-green. Run what you ship with structured logs, traces, metrics, dashboards, alerts, first-line technical support, optimization, and ongoing support for internal teams and external users. Technical background: Strong end-to-end TypeScript and React experience across client, server, API design, and serverless or edge runtimes. Remix, Next.js, Vite, and Cloudflare Workers experience is valuable. Experience building LLM-powered products beyond basic API calls, in…

Read this first — two non-negotiables Go is the job, not a bonus skill. We're only considering candidates with 5+ years of hands-on, production experience in Go . If Go isn't (one of) your primary languages, this role won't be a match — and we'd rather save you the time. You must live in a European timezone (UTC−1 to UTC+3). This is a hard requirement. Applications from outside this range won't be considered, regardless of how strong the profile is. Still with us? Great — here's why this role is worth your attention. Who we are We're Jobtome ( https://weare.jobtome.com/ ) — an HR Tech company building the modern web applications that companies use to run complex hiring and recruitment workflows at scale. Our products are highly interactive, data-driven, and built for real-world usage — not demos. We work with a strong product mindset, short feedback loops, and a pragmatic engineering culture: quality, ownership, and code we're still proud of a year from now. The role You'll join our engineering team as a Senior Go Backend Developer and take real ownership of critical backend systems and services — not ticket-pushing, actual ownership. You'll design, build, and evolve the backend services that power our products, weigh in on architectural decisions, improve system reliability, and help shape how backend engineering is done across the company. This is a hands-on senior role: you'll write production Go every day and be deeply involved in technical decisions that have real impact. Quick reminder before the details 5+ years of production Go experience — required Based in a European timezone (UTC−1 to UTC+3) What you'll do Design, build, and maintain backend services written in Go Build and evolve APIs (GraphQL and/or REST) behind complex product workflows Design scalable, reliable, and maintainable backend architectures Work closely with frontend engineers, product managers, data engineers, and designers Contribute to data modeling, business logic, and performance optim…
