Jobs with public salary

Remote | Full-time | $2,000–3,000/month

We are looking for a Middle / Strong Middle Full-Stack Developer to join a newly forming technical team responsible for maintaining and developing existing CRM and web-based trading platform products.

The systems are already in production and used across multiple environments.

At the current stage, the majority of development work involves investigating and fixing existing issues, with additional product improvements and new functionality being introduced continuously.

This is not a role where every task comes with detailed technical implementation instructions.

We are looking for a developer who can gradually take ownership of issues and independently move from problem reproduction to root-cause analysis and implementation.

Previous experience in FinTech, Forex, CFD, or trading is not required. Product and business logic will be explained during onboarding.

What you will work with

The product environment includes:

• Web-based CRM
• Web-based CFD/trading platform
• Existing production codebase
• JavaScript-based web applications
• REST APIs
• WebSockets and real-time functionality
• Third-party integrations
• Multiple production environments
• GitHub-based development workflow

The existing codebase is complex and contains legacy functionality, so the ability to understand and debug unfamiliar code is important.

Responsibilities

• Investigate and fix bugs in existing CRM and trading platform functionality
• Reproduce reported issues using provided scenarios and production/test data
• Analyze application behavior and determine the actual root cause of problems
• Work with frontend and backend code
• Debug REST API and WebSocket-related issues
• Work with real-time application functionality
• Implement improvements and new functionality
• Work with third-party API integrations
• Read and analyze application and server logs when required for debugging
• Test your own changes before handing them over to QA
• Work closely with QA and DevOps
• Maintain existing functionality while implementing fixes to avoid regressions
• Work with Git/GitHub as part of the development process
• Document important technical implementations and changes when necessary
• Gradually develop a strong understanding of the system architecture and product logic

Expected workflow

For most technical issues, we expect the developer to gradually become capable of owning the complete development cycle:

Issue → Reproduce → Investigate → Identify root cause → Implement fix → Self-test → QA verification → Release

During onboarding, assistance will be provided with the existing codebase, product architecture, and trading-specific logic.

After onboarding, we expect increasing technical independence.

Requirements

• 3+ years of commercial Full-Stack development experience
• Strong JavaScript/web development fundamentals
• Commercial frontend and backend development experience
• Experience working with existing production applications
• Experience debugging complex application issues
• Experience with REST APIs
• Experience with WebSockets or other real-time functionality
• Experience with third-party API integrations
• Understanding of client-server architecture
• Ability to analyze application logs and technical errors
• Git/GitHub experience
• Ability to understand and work with an unfamiliar/legacy codebase
• Ability to identify root causes instead of applying temporary surface-level fixes
• Ability to test your own changes before passing them to QA
• English — Intermediate or higher

Experience with Node.js and modern JavaScript frontend frameworks is highly relevant to our environment.

Exact product architecture and existing implementation will be introduced during technical onboarding.

Trading experience

Previous Forex, CFD, brokerage, or FinTech experience is not required.

We will explain the required business logic, including concepts related to:

• Trading accounts
• Orders and positions
• Prices
• P&L
• Margin
• Leverage
• Trading symbols
• CRM workflows

We care more about your ability to understand complex systems and learn new domain logic than previous trading experience.

What we expect during the first months

The first 1–3 months will include technical and product onboarding.

The existing product is complex, and we do not expect a new developer to understand the entire system immediately.

After approximately three months, we expect you to:

• Understand the core architecture and product functionality
• Navigate the existing codebase confidently
• Reproduce and investigate issues independently
• Understand dependencies between CRM, trading platform, APIs, and real-time functionality
• Require significantly less guidance for standard bugs
• Take ownership of assigned technical issues
• Communicate clearly with QA, DevOps, and the Project Manager

Deployment

Production infrastructure and deployment processes are primarily owned by DevOps.

Developers are expected to understand the release process and cooperate closely with DevOps during deployment and troubleshooting.

Working conditions

• Fully remote
• Full-time
• Monday–Friday
• Working hours: 09:00–18:00 GMT+3 / 10:00–19:00 GMT+4
• No regular night/weekend on-call requirement
• Probation/onboarding period: 1–3 months
• Compensation: $2,000–3,000/month, depending on technical level and experience
• Long-term cooperation
• English: Intermediate or higher

What is important to us

We value developers who:

• Are available and responsive during agreed working hours
• Communicate when they are blocked instead of disappearing
• Notify the team in advance about planned absence
• Take responsibility for their work
• Investigate problems before asking for step-by-step instructions
• Verify their own fixes
• Consider the impact of a change on existing functionality
• Communicate technical problems clearly
• Are comfortable saying when they do not know something and then investigating it

We are building a new technical team around an existing production product, so reliability, ownership, communication, and the ability to become independent are as important as writing code.

About Us

Mamma Mia Covers is a US-based DTC company serving the American and Canadian markets, and the exclusive distributor of the Italian brand PAULATO by GA.I.CO in the US and Canada.
Since 2018, we've built a recognizable brand in the slipcover category — patented product, sold through Shopify (our DTC website) and Amazon US, with Wayfair growing as our channel into Canada. Featured in Inc. 5000, team of 40+ people, own warehouses in the US.
We're actively expanding into new product categories, testing new ideas, and building the product team that will take us there.

Returns aren't just an operational metric — they affect profit and brand reputation across every channel we sell on. We're growing the team to take this on properly, with someone dedicated to solving it systematically.

The Role

This is an analytical, hands-on role at the intersection of product and data.

We needs someone who owns the problem end-to-end: digging into the real cause behind returns, building and testing hypotheses, and pushing confirmed fixes through to implementation.

What We Offer

Financial Stability: 

• $1,500–2,000/month depending on experience + quarterly bonus
• Transparent, paid 2-month probation period 

Flexible Work Format: 

• Remote, Full-time
• Required overlap 12:00–18:00 Kyiv time (so we can move fast on live issues), flexible outside that window

Learning & Development:

• Professional courses and certifications
• Freedom to implement new tools and processes

Paid vacation: 

• 21 days + extra days off for important personal events

Career Growth: 

• This is a new role, and where it goes next depends on you — either deep into returns as a niche expert (rare on the market, real specialist status), or broader into a full Product Manager scope with returns as a core KPI. Both paths are open.

What You'll Do

Root Cause Analysis

• Deeply analyze the returns situation — independently trace the real cause behind returns for specific SKUs and categories, including your own competitor and market research
• Optionally draw on data support from our Product Research Specialist — but you own the analysis start to finish

Hypothesis & Testing

• Formulate hypotheses (for example: customers perceive a product's color as lighter/darker than shown, or a size chart doesn't match real expectations)
• Test hypotheses through A/B testing of visuals, descriptions, and content variations

Implementation & Results

• Present concrete change proposals to leadership for sign-off
• Implement approved changes yourself, working alongside the R&D team
• Track results after implementation
• Report back with clear conclusions — what worked, what didn't, and the actual impact on return rate — and jointly assess next steps

What We're Looking For

Must have

• Product Manager experience, Middle+ (2–3+ years)
• Real, hands-on experience analyzing returns/reviews/complaints in e-commerce at the SKU level — not theoretical process knowledge, but a confirmed case with measurable positive impact: a specific returns problem you personally worked through, with a result you can point to
• Experience with competitor research
• Confident use of Helium10 or similar research tools
• Experience with A/B testing platforms (PickFu or similar, Amazon Manage Your Experiments)
• Confident with Google Sheets/Excel
• English: Upper-Intermediate+

Nice to have

• Experience testing visual or color perception (part of returns often comes from customers seeing a color lighter or darker than reality)

If this sounds like you

• You're patient and detail-obsessed with numbers — comfortable with methodical, unglamorous data work
• You're self-directed — you see what needs analyzing next without being told where to look
• You communicate findings and proposals clearly and in a structured way, in writing and out loud
• You stay focused on your own metric and don't get pulled into other people's tasks

Apply and tell us about a specific returns or product issue you diagnosed and fixed — what changed, and what the measurable result was. We review every application personally and get back within 3 business days.

Block-Builder Engineer

Who we are:

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.

About the Product:

An advanced block construction platform operating on the Ethereum mainnet that processes order flow, transaction bundles, and submits finalized blocks through relay networks in real time. It addresses neutral and efficient block building to unlock new decentralized finance capabilities, including intrablock lending and execution extensions. The system handles high-throughput data pipelines and strict latency requirements, backed by comprehensive observability and analytics to drive iterative improvements based on live production metrics. Strong engineers are essential to maintain system health under real-time load, verify data-driven hypotheses, and innovate on core protocol logic.

About the Role:

The Block-Builder Engineer will join an experienced team in Kraków or Warsaw to develop and maintain a next-generation Ethereum block construction system. You will own pipeline components that ingest order flow and transaction bundles, manage relay submission paths, and ensure stable performance under real-time load. Your work will include building and refining observability platforms, conducting controlled A/B experiments, and driving reliability improvements such as panic mitigation and latency regression detection. As you ramp, you will contribute to optimization-driven block building logic, on-chain intrablock lending protocols, and an execution extension, gaining autonomy and deep technical ownership across the core stack.

Key Responsibilities:

- Integrate and process order-flow ingestion, bundle and transaction handling, back-pressure management, and reintegration of data for block inputs.

- Develop and maintain relay submission paths to ensure end-to-end block delivery under production load.

- Build and enhance telemetry and dashboards using Grafana, Prometheus, Loki and SQL to provide trusted observability.

- Diagnose and correct measurement issues—broken counters, misleading dashboards, and erroneous denominators—to maintain metric accuracy.

- Design, execute and analyze controlled A/B experiments in production, reporting findings objectively, including inconclusive results.

- Identify and resolve system panics, dropped messages, and latency regressions, with automated tests to prevent recurrence.

- Optimize data pipelines and processing systems for high-throughput, low-latency performance.

- Contribute to the development of intrablock lending protocols and associated trusted-execution components.

- Collaborate on an execution extension (BEX) and future protocol and exchange-layer enhancements.

Required Competence and Skills:

- 2–4 years of professional software engineering experience shipping and operating production systems.

- Minimum 2 years working on Ethereum or other EVM-compatible blockchains.

- Proficiency in Rust or strong systems experience in Go, C++ or Java with eagerness to adopt Rust.

- Solid understanding of concurrent and real-time code within large, existing codebases.

- Strong SQL skills and practical experience with Python for data analysis and tooling.

- Familiarity with monitoring and analytics tooling and a drive to ensure metric correctness.

- Rigorous engineering habits, including comprehensive testing and clear distinction between verified and assumed behavior.

- Data-driven mindset with a habit of querying logs and databases to validate change impact.

Nice to Have:

- Exposure to Ethereum block-building protocols (PBS/MEV), smart contract interactions, or trading systems.

- Experience with high-throughput data pipelines, time-series databases, or large-scale analytics.

- Familiarity with Ethereum client internals (reth, geth, revm) or deploying services on Kubernetes and Docker.

Why Us:

We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).
