Jobs

Project Description:

We build an in-house trading platform covering order management, execution, and data analysis. The front end is a set of TypeScript/React apps running in a desktop container and streaming real-time data.
We're hiring a hands-on SDET to own UI test automation: extend our Playwright framework, make streaming, multi-window workflows testable, and add quality gates to CI, including front-end performance. You'll co-architect and co-own a unified testing framework with our backend SDET. It covers UI, API, messaging, data and performance tests in one place.

Responsibilities:

• Co-architect and co-own, with our backend SDET, a unified testing framework that covers every area we test:
◦ Shared foundations: fixtures, test data, configuration, environments and reporting are shared across UI, API, Kafka, database and performance suites.
◦ Cross-layer scenarios: one scenario can cross layers. For example, a test places an order in the UI, then checks the resulting event and the database record.
◦ One quality view: results from every suite feed a single view of release quality.
• Design, build and maintain end-to-end and component tests with Playwright and TypeScript for trading and analytics workflows.
• Extend our shared test toolkit: page objects, fixtures, and mocks of desktop-container APIs.
• Build front-end harnesses for real-time data: mocked WebSocket and REST responses, controlled test data, and deterministic replay of streaming updates.
• Cover UI failure modes: disconnects and reconnects, expired sessions, permission failures, bursty feeds, and stale data.
• Own front-end performance testing:
◦ Startup and responsiveness: measure app startup and time-to-first-data, and check that the UI stays responsive under high update rates.
◦ Grid behaviour at scale: measure render and scroll performance of grids with tens of thousands of rows.
◦ Container resources: track memory growth and leaks in long-running desktop sessions, and CPU cost per window.
◦ Regression gates: turn the results into budgets that fail CI on a regression.
• Build and maintain isolated, on-demand test environments on Linux and AWS:
◦ Lifecycle: environments are created per branch or per run, start with seeded data and known state, and are torn down automatically.
◦ Isolation: test runs don't interfere with each other or with shared environments.
• Validate front-end/back-end contracts and payload schemas.
• Run UI suites in CI/CD: sharded parallel runs, scheduled regressions, and reporting on pull requests.
• Make failures diagnosable: Playwright traces, screenshots and video, and correlation with telemetry.
• Work with UI engineers, business analysts and traders to automate critical workflows and define QA acceptance criteria.
• Use AI-assisted tools where they help with writing, maintaining and triaging tests.

Mandatory Skills Description:

• 5+ years of UI test automation, including designing or significantly extending a framework.
• Strong TypeScript/JavaScript and Node.js skills, with substantial hands-on Playwright experience. Strong Cypress or Selenium experience plus willingness to move to Playwright is also fine.
• Working Python skills (pytest, Playwright for Python): test tooling, data setup, backend checks inside UI scenarios, and contributing to the shared framework.
• Experience testing React apps with complex data grids (AG Grid or similar), dynamic forms and heavy client-side state.
• Experience mocking network traffic in the browser (REST and WebSocket) and testing authentication flows.
• Front-end performance testing experience:
◦ Profiling: Chrome DevTools Performance and Memory panels, and the Lighthouse and performance APIs.
◦ Diagnosis: finding long tasks, layout thrashing and memory leaks.
◦ Budgets: setting performance budgets and enforcing them in CI.
• CI/CD experience with Azure DevOps (preferred) or Jenkins/GitHub Actions, and Git.
• Experience building isolated test environments:
◦ Linux: comfortable on the command line, with shell scripting, processes, networking and log troubleshooting.
◦ Docker: Docker and Docker Compose.
◦ AWS: EC2, ECS or EKS, S3, IAM, VPC and CloudWatch.
◦ Infrastructure as code: Terraform, CloudFormation or CDK.
• Strong reliability habits: isolated tests, deterministic waits instead of sleeps, controlled retries, and triage of flaky tests.
• Experience with test reporting and traceability (Playwright reports, Allure, Azure Test Plans, TestRail).
• Clear communication and good documentation.

Nice-to-Have Skills Description:

• Trading or buy-side experience: OMS/EMS, algos, positions, allocations, or risk.
• Java exposure, enough to read service code and contribute to backend suites in the shared framework.
• Desktop container automation: Electron, OpenFin, or similar.
• Component testing (Vitest or Jest). Storybook visual or interaction testing.
• Accessibility and visual-regression testing.
• React Profiler and familiarity with React rendering performance (memoization, virtualization).
• OpenTelemetry or similar real-user-monitoring tools, and using production RUM data to pick performance test scenarios.

Project Description:

We build an in-house trading platform covering order management, execution, and data analysis. It runs on a distributed, event-driven backend.
We're hiring a hands-on SDET to own backend test automation: service, integration, contract, data, resilience and performance testing across the platform. You'll co-architect and co-own a unified testing framework with our UI SDET. It covers UI, API, messaging, data and performance tests in one place.

Responsibilities:

Co-architect and co-own, with our UI SDET, a unified testing framework that covers every area we test:
◦ Shared foundations: fixtures, test data, configuration, environments and reporting are shared across REST, WebSocket, Kafka, database, performance and UI suites.
◦ Cross-layer scenarios: one scenario can follow a workflow from the UI through services and events to the database.
◦ One quality view: results from every suite feed a single view of release quality.
• Design and build automated service, integration and contract tests for REST APIs, WebSocket services, and Kafka producers and consumers.
• Test event-driven flows end to end: message ordering, idempotency, at-least-once and exactly-once semantics, replays, offset handling, dead-letter queues, and schema evolution (Avro, Protobuf, JSON Schema, Schema Registry).
• Build harnesses with controlled test data and service virtualization so suites run consistently and can be repeated.
• Design and build isolated, on-demand test environments on Linux and AWS:
◦ Lifecycle: full service stacks (services, Kafka, databases) are created per branch or per run, start with seeded data and known state, and are torn down automatically.
◦ Isolation: test runs don't interfere with each other or with shared environments.
◦ Infrastructure: the environments are defined as code, with attention to cost.
• Write data-validation tests across relational and analytical databases. Cover reconciliation and aggregation correctness.
• Cover resilience and failure modes: broker and consumer outages, network partitions, timeouts, throttling, slow consumers and backpressure, reconnects, and authentication failures.
• Own backend performance testing:
◦ Latency and throughput: design and run load, stress, soak and spike tests on services, messaging pipelines, streaming and query APIs.
◦ Baselines and regressions: set baselines and service-level targets (p50/p99 latency, throughput, consumer lag), and catch regressions in CI.
◦ Bottlenecks: profile them down to the CPU, GC, query or network layer.
◦ Database queries: track query performance on analytical stores. Know how query shape and data volume drive response time.
• Own backend test execution in CI/CD: parallel runs, scheduled regressions, environment setup and teardown, and release quality gates.
• Make failures diagnosable: structured logs, distributed traces (OpenTelemetry), correlation IDs across services, and clear reports.
• Work with backend engineers, infrastructure, business analysts and traders to define and automate critical business workflows.
• Use AI-assisted tools where they speed up writing tests and analysing failures.

Mandatory Skills Description:

• 5+ years of backend or service test automation, including framework design.
• Strong Python (pytest, requests, asyncio, confluent-kafka or similar) for test frameworks, tooling and data validation.
• Strong Java (JUnit 5, REST Assured, AssertJ, or similar) for testing JVM services.
• Working TypeScript and Node.js skills: contributing to UI and cross-layer suites in the shared framework, and Node-based tooling (k6 scripts, Playwright API tests).
• Hands-on Kafka experience: producing and consuming in tests, consumer groups, partitions and offsets, serialization and schema registry, and Kafka Streams or Connect.
• Solid networking fundamentals: TCP/IP, HTTP/1.1 and HTTP/2, WebSockets, TLS, DNS, load balancers, latency and packet loss. Able to debug with tcpdump/Wireshark, curl and similar tools.
• Strong SQL and database experience (PostgreSQL, SQL Server, or similar) for test data setup, verification and cleanup. Familiarity with columnar or analytical databases.
• Hands-on performance and load testing:
◦ Tools: k6, Gatling, JMeter or Locust, including Kafka throughput benchmarking.
◦ Profiling: JVM tuning and profiling (GC, JFR, async-profiler) or Python profiling.
◦ Analysis: reading latency distributions and percentiles correctly, including coordinated omission.
• API, authentication and contract testing: OAuth/JWT flows, payload and schema validation, and service virtualization (WireMock, MockServer, Hoverfly).
• Experience building isolated test environments:
◦ Linux: strong command-line skills, with shell scripting, systemd, processes, networking and performance troubleshooting.
◦ Containers: Docker, Docker Compose and Testcontainers.
◦ AWS: EC2, ECS or EKS, S3, IAM, VPC, MSK or RDS, and CloudWatch.
◦ Infrastructure as code: Terraform, CloudFormation or CDK.
• CI/CD with Azure DevOps or Jenkins, and Git.
• Strong reliability habits: isolated tests, controlled retries, failure-mode testing, and triage of flaky tests.
• Clear communication and good documentation.

Nice-to-Have Skills Description:

• Trading or buy-side experience: OMS/EMS, the FIX protocol, market data, positions, allocations, or risk.
• kdb+/q, or other time-series databases used for tick data.
• Contract testing with Pact. Property-based testing (jqwik, Hypothesis).

• Experience owning parts of a production system end to end
• Fluent English for daily work with the client team

The role is full time, 40 hours a week, long term, with a working day that overlaps European business hours. Individual engineers only, no agencies.

How we hire: a call with our CTO about your ComfyUI work, your product work and your code, then a call with the client's team. Both are live, with screen share and without AI assistants.

To apply, open your application with a link to a ComfyUI workflow you built or ran, or one sentence on what it did. Applications without it will not be read.

Please provide your CV and LinkedIn profile. We demand your LinkedIn profile with actual working experience to move forward with your application!

🚀 We're Hiring: PPC & SEM Campaign Manager Home Services | US Market | Full-Time | PST Hours

We're a performance-driven digital marketing agency specializing in home services and construction lead generation for the US market. We're looking for a hands-on Campaign Manager who owns results end to end — from strategy to the qualified phone call.

This is not a role for someone who only knows how to run ads. We need someone who understands the full journey: from search intent to phone call, from phone call to qualified opportunity, from opportunity to real revenue for a local service business.

⚠️ Non-Negotiable Requirements — Please Read Before Applying: → Full-time availability during US PST working hours 

→ Native-level English — written and verbal, non-negotiable 

→ Proven hands-on experience with the US market across Google, Meta, Bing, and native 

→ Solid, verifiable work history — not freelancers filling time between gigs 

→ Home services / construction experience required — e-commerce, SaaS, or fintech background alone is not enough

What you'll own: 

→ Plan, build, and manage paid campaigns across Google Ads, Meta, Microsoft/Bing, Taboola/Outbrain, Yelp Ads, Google Local Services Ads, and Nextdoor/LinkedIn as needed 

→ Create and optimize full-funnel lead generation strategies — audience targeting, ad copy, landing pages, tracking, and lead-nurturing funnels 

→ Monitor performance and continuously improve KPIs — cost per lead, lead quality, conversion rate, and ROI (not just clicks) → Own setup and integrity of conversion and call tracking so every lead is measured accurately 

→ Stay current on platform updates, A/B testing strategies, and market trends in home services 

→ Build repeatable systems, SOPs, reporting structures, QA processes, and campaign management workflows that allow the team to scale without losing quality 

→ Maintain strict QA discipline before every launch — budgets, geo-targeting, tracking, landing pages, phone numbers, forms, conversion actions, and campaign settings

AI & Automation — Core to This Role: 

→ Use AI to draft, test, and iterate ad copy and creative concepts at speed — with the judgment to edit and direct that output, never paste it raw 

→ Use AI for audience and keyword research, competitor analysis, and market intelligence 

→ Build reporting and analysis workflows that turn raw platform data into clear, decision-ready insights 

→ Be fluent in platform-native AI: Google Performance Max & Smart Bidding, Meta Advantage+, and AI-assisted creative — knowing when to trust automation and when to override it 

→ Build repeatable AI and automation systems using tools like Make.com, Zapier, or Google Apps Script to eliminate manual, repetitive work

Tracking & Attribution: 

✅ Hands-on with call tracking (CallRail or similar) and call-driven conversion measurement 

✅ Strong with GA4, Google Tag Manager, and conversion tracking across platforms 

✅ Familiar with offline conversion imports and server-side tracking to feed real lead quality back into platforms 

✅ You care what happens to a lead after the click — not just the cost of the click

Must-Haves: 

✅ Proven track record managing paid media campaigns targeting the US market 

✅ Deep knowledge of the home services vertical — remodeling, HVAC, solar, roofing, garage doors, windows, etc. 

✅ Demonstrated success generating high-quality leads at scale — measured by qualified leads and CPL, not vanity metrics 

✅ Experience building and managing end-to-end ad funnels from cold traffic to converted lead 

✅ Hands-on proficiency with Google Ads, Meta Ads Manager, Microsoft/Bing Ads, native platforms, and Google Tag Manager 

✅ Native-level English — strong written and verbal communication 

✅ Experience with Yelp Ads and Google Local Services Ads (LSA) — strong advantage 

✅ Familiarity with automation and lead-nurturing platforms — major plus

Who You Are: 

→ Independent, proactive, and execution-driven — you don't wait to be told what to do 

→ Data-minded but creative — constantly testing, iterating, and pushing performance boundaries 

→ You embrace AI and automation as tools for scale and smarter decisions — not as a gimmick or a crutch 

→ You think like a strategist and work like an operator 

→ You want to help small businesses grow — energized by making a real difference for an SMB owner, not by chasing the biggest budget

→ Loyal, analytical, hungry for results, and excited to grow as part of a small, sharp, accountable team

This role is NOT for you if: 

✖ Your background is primarily e-commerce/DTC, SaaS, or fintech 

✖ You rely on grey-hat or aggressive black-box agency tactics 

✖ You only want to direct strategy from above — we need someone hands-on, detail-oriented, willing to build, check, fix, test, and improve directly 

✖ You're a freelancer looking to fill time between gigs

About the project:
A connected beauty technology company building a smart mirror (in-store, running proprietary software) and a mobile app on iOS and Android. Behind both sits the company’s intelligence layer, which includes an AI Skin Analyzer, a virtual makeup artist, and a routine builder. Skin analysis already runs on proprietary models — the next step is live, realistic rendering on a real face, on a phone and on a wall-mounted mirror.

Working hours:
Our engineering team works in Central European time, and our leadership team is on the US East Coast. Your working day ends at 20:00 CET, and dependable availability through the afternoon until then is a firm requirement of this role. That’s the window where your day overlaps with the US morning, when decisions get made, priorities get set, and cross-team questions get answered.

The role:
This role has more ownership than most: there is no existing face-rendering team to join, and you’ll set its standards. It also has more physical hardware than most software roles — you’ll work with a real Smart Mirror and real devices, and some of the hardest problems (light, skin, cameras) only show up there.

We are hiring an engineer to own the real-time face rendering behind three products:

• Treatment Preview — previews cosmetic treatments on the user’s own face (wrinkle smoothing and brow lift for neurotoxin-style treatments, lip and cheek volume for dermal fillers);
• AR product try-on — letting a shopper see a specific lipstick, blush, or foundation shade from the catalog on their own face, live, with accurate color matching;
• Guided makeup looks — walking a user step by step through a complete makeup look rendered live on their own face, built on the same shared engine.

This is a hands-on senior IC role. You’ll be the person who knows how the face engine works, building it rather than integrating someone else’s. The Flutter app team builds the screens around your work, and ML engineers own the analysis models. You own everything between the camera frame and the pixels on screen.

What you’ll work on:

• Build a shared face-rendering engine for Android and iOS: camera frames in, face tracking, region masks and warps, GPU shading, and frames out to a Flutter texture;
• Build Treatment Preview: smoothing, warps, and volume effects rendered behind a Flutter texture, guided by a wrinkle mask that updates slower than the frame rate, keeping effects stable on a moving face;
• Build realistic makeup rendering: lips, cheeks, base, eyes, with finishes (matte, satin, gloss, shimmer) that respond to light and work across the full range of skin tones;
• Connect the product catalog to the face: a pipeline that turns a product’s shade and finish into rendering parameters, scalable to thousands of products;
• Build multi-step guided makeup looks on the new engine;
• Optimize for real hardware: modern iPhones, mid-range Android phones, and a Smart Mirror running a 4K USB camera all day in-store;
• Measure quality: stability, color accuracy against real product swatches, and failure rates by skin tone, lighting, and face angle.

Tech stack:

• Rendering: OpenGL ES 2.0/3.0 (GLSL) on Android, Metal on iOS;
• Face geometry: ML Kit face detection for capture; dense face landmarks and blendshapes for rendering;
• Image processing: C++ with OpenCV;
• Native: Kotlin and C++ on Android, Swift on iOS;
• App: Flutter (Dart) with Bloc — you’ll write the platform-channel and texture boundary, and the app team writes the UI;
• Test devices: iPhone, Galaxy-class Android, and the company’s Smart Mirror.

Requirements:

• 5+ years of professional software engineering, including substantial real-time graphics work — you have written and shipped GPU shaders (GLSL, Metal, HLSL, or similar) in a product that ran at frame rate on real devices. This is the single most important requirement;
• Hands-on work with face tracking or face geometry: landmarks, face meshes, UV mapping, region masks, warps, or morphs (AR filters, virtual try-on, avatars, and face retouching all count);
• Native mobile development on Android (Kotlin/Java, NDK/C++) or iOS (Swift/Objective-C), with willingness to work on both;
• Experience putting ML models in a real-time pipeline, designing rendering around the model being the slow part;
• Practical grasp of color and image processing: color spaces and gamma, blending, frequency separation, filtering;
• An eye for realism and the discipline to measure it;
• Comfort working in an existing codebase;
• Clear English, spoken and written, with a working style that holds up across time zones.

Will be a plus:

• Shipped a virtual makeup try-on, beauty filter, or face-retouching product;
• Flutter external textures or platform views, or embedding native rendering in any cross-platform UI framework;
• Training or fine-tuning segmentation models (face parsing, lips, skin) and building the datasets behind them;
• Physically based shading, or measuring color from real product swatches;
• Experience with inclusive evaluation across Fitzpatrick skin types, lighting conditions, and ages;
• Low-level Android camera work (Camera2, UVC/external cameras) or embedded devices;
• Knowledge of aesthetic medicine, or experience building consumer features near medical claims.

Not required — please apply anyway if you don’t have these:

• Beauty or cosmetics domain knowledge;
• Flutter or Dart experience;
• A computer science or graphics degree.
