Overview

We are toogeza, a Ukrainian recruiting company that is focused on hiring talents and building teams for tech startups worldwide.

Currently, we are looking for a Senior Software Engineer (Systems & Algorithms) for Spinlab.

Location: Remote Job Type: Full-Time

What you need

Who we're looking for

An experienced engineer who enjoys writing non-trivial code by hand, with a background in areas like systems programming, distributed systems, embedded systems, telecom and VoIP, desktop software, trading systems, video and audio processing, databases or developer tools.

Strong fundamentals matter more to us than knowing specific frameworks. The product runs on TypeScript / Node.js, and we welcome engineers with a background in other languages who are ready to switch.

Requirements

10+ years of software engineering, and you still write code yourself every day.
Solid experience with a compiled or systems language (such as C++, Rust, Go, Java, or C#), on projects beyond typical CRUD
Projects where you designed and wrote low-level or algorithmically complex logic yourself: a network protocol, an engine, a codec, a storage layer
Comfortable implementing data structures and algorithms by hand, without relying on libraries or AI assistants.
Ready to work primarily in TypeScript / Node.js.
Working English.

Nice to have

Production TypeScript / Node.js and NestJS, strict-mode TypeScript.
Clustered ClickHouse, Kafka as a producer, Redis beyond GET/SET (pipelines, Lua, distributed locks).
Distributed systems under load: idempotence, retries, caching.
Browser internals: Canvas, WebGL, AudioContext, cross-origin iframes, storage partitioning. Shipping a third-party SDK under tight size and privacy constraints.
Docker, Helm templates, GitHub Actions.
Conventional Commits, a strong review and documentation culture.

Stack: TypeScript, Node.js, NestJS · ClickHouse, Kafka, Redis · Web Components SDK · AWS

(EKS), Helm, ArgoCD, GitHub Actions · Datadog.

Scope of ownership

Backend: high-RPS collection and identification endpoints, a Redis-backed key-value store, Kafka producers, ClickHouse migrations
Browser SDK: evolving signals and fighting regressions on Safari and iOS.
Operations: observability (APM, RED signals, SLO alerts), GitOps delivery via Helm and ArgoCD.
A "whole feature" mindset – willingness to own delivery end-to-end, including the UI, rather than handing it off

A B2B web analytics and user-identification platform for browsers and webviews

Fingerprint: browser-based user identification for browsers and webviews. A JavaScript SDK collects device signals (Canvas, GPU, screen, timezone, language, network) and assigns each visitor its own identifier.
Real-time analytics: high-RPS event collection and processing, with ClickHouse-based reporting for customers.

This role works mainly on Fingerprint and the event pipeline behind it.

Pay and benefits

Work on meaningful data products and shape them with your vision.
25 vacation days + 15 sick days + 1 birthday leave.
Budget for English classes.
Budget for health insurance.
Annual education & development budget.
Remote-friendly culture with a small, dedicated team.

What’s next?

If this role sounds like a fit – we’d love to hear from you! Just send over your CV and anything else you’d like us to consider.

We’ll review everything within five working days, and if your background matches what we’re looking for, we’ll get in touch to set up a call and get to know each other better.
