About the Project

When a new Diablo season or Path of Exile league drops, millions of players open Maxroll before they start to play.

Maxroll.gg, part of IGN, is the go-to companion for RPG players, with over 25 million visits a month. We cover Diablo IV, Path of Exile 1 and 2, Lost Ark, Last Epoch, World of Warcraft and more, with expert guides, build planners and deep game databases. Launch days bring massive traffic spikes, and every player expects fresh, accurate data instantly. Keeping that fast is the job.

If you’ve ever spent an evening min-maxing a build, you already know our users.

Everything runs on one TypeScript stack:

• a Remix frontend over headless WordPress
• a planner service for player builds
• background jobs for game data, search, analytics and revenue
• a new game data platform with a keyed API and a published React SDK

We validate at the boundary and derive everything else. Zod checks all data coming into the system, and types flow from the database table through to the React component. Strict lint rules block any and as. Anything important is covered by a lint rule or a build check, so a rename breaks the build, not production.

The Work

You will be:

- APIs: building and maintaining REST and GraphQL APIs in TypeScript (Fastify, Hono) for user profiles, subscriptions and game data. This includes authentication, rate limits and typed contracts.

- Databases: designing schemas and writing queries for PostgreSQL and MySQL (Prisma, Drizzle). The data includes versioned game data and player-made builds, and the migrations run on tables that are in live use.

- Analytics: running our ClickHouse pipelines: per-request logs rolled up over time with materialized views, article and revenue metrics, and the queries behind our dashboards.

- Caching: owning the cache layers end to end: Redis-compatible stores, query caching, a tag-invalidated cache, HTTP cache headers, and CDN purges when content changes.

- Background jobs: building and running scheduled jobs and queue consumers (NATS). They sync game data, leaderboards and in-game events, index content in Meilisearch, generate sitemaps, and process Stripe webhooks, payouts and data-deletion requests.

- Integrations: working with third-party APIs such as Stripe, Discord, Blizzard, IGDB, Steam and YouTube, handling retries, backoff and their rate limits.

- Media pipelines: processing game images into map tiles, sprite sheets and responsive image sizes.

- Performance: keeping responses lean for our Remix and Next.js pages, because payload size and time to first byte affect PageSpeed and SEO. You'll also change React code when a feature reaches into the frontend.

- AI agents: working with AI coding agents (Claude Code, Cursor) every day. That means directing them, reviewing their output, and maintaining the guardrails that make their changes safe to merge (tests, lint rules, build checks, agent instructions).

- Shipping: deploying through Docker, GitHub Actions and Kubernetes.
 

Technical Stack / Requirements

- 5+ years of backend experience with TypeScript on Node.js (Bun is a plus)

- A strong command of TypeScript's type system: generics, inference, discriminated unions and narrowing, plus schema validation with Zod or similar

- Strong SQL on PostgreSQL and/or MySQL: schema design, indexing, reading query plans, migrations on live data, transactions and locking

- Experience running an analytical database at production volume (ClickHouse preferred; BigQuery, Druid or similar also counts)

- Experience designing caching: Redis or a compatible store, invalidation strategies, HTTP caching headers, CDN behavior

- Experience designing and consuming REST and GraphQL APIs, including authentication and rate limiting

- Experience with background jobs and message queues, including what should happen when a job runs twice or not at all

- Experience on a production, high-volume, user-facing application

- Experience leading a product from inception to production

- Daily, hands-on use of AI coding tools (Claude Code, Cursor or similar) in a real codebase, and a clear sense of when their output needs checking

- Comfortable reading and changing React code when a change crosses into the frontend

- Passion for gaming
 

Nice to have

- shadcn/ui and Tailwind CSS

- Our current stack: Remix, Next.js, Fastify, Hono, Prisma, Drizzle, Zod, Apollo GraphQL, Meilisearch, NATS, Ory, Stripe, Nx, Bun

- Strict lint setups: typescript-eslint strictTypeChecked, custom lint rules, architecture boundaries

- Docker, Kubernetes, GitOps (ArgoCD), GitHub Actions, External Secrets

- Payments and subscriptions (Stripe checkout, webhooks, promotion codes)

- Writing agent instructions, skills or custom tooling for AI coding agents

- Experience building a game tool, such as a database, interactive map, calculator or planner
 

What we offer

- Stable, long-term work on a product used by millions of people.

- Direct communication.

- A highly technical environment with a small team that values each individual's work and contributions.

AP US Tax Compliance and Advisory is a US tax firm based in Israel serving Israeli investors with US real estate and US citizens living abroad. Owner-run, growing, and building its own technology.

THE PROJECT

We prepare US tax returns in Wolters Kluwer CCH Axcess and have automated most of the preparation through CCH's REST API: import, calculation, printing, review memos, e-file qualification and release all run from code today. What runs in scripts must become a product before the 2027 filing season: a client platform where clients (or their AI assistants) complete a structured intake, the system extracts data from documents, prepares the return through CCH, routes it to a human reviewer and signer, collects an e-signature and payment, releases the e-file and delivers the result. The design document, data model, state machine, API and security model are written. You will be the first engineer and you will own the backend.

RESPONSIBILITIES

- Backend architecture and implementation: Python 3.12, FastAPI, SQLAlchemy/Alembic, Postgres, a job queue, workers, webhooks.

- The CCH Axcess API module as a server-side job runner: one in-flight job per return, global concurrency limits, exponential backoff on locks, idempotency keys, prompt handling, structured results, parked-job alerts.

- Security engineering: PII vault with field-level encryption (KMS), tokenized payload assembly, append-only audit log, RBAC with step-up MFA for sensitive actions, PII-free logging with a redaction layer, secrets manager, backups and restore tests.

- Integrations: Stripe (payments, webhooks), an e-signature vendor with identity verification, Google Drive, transactional email, WhatsApp Business API, Anthropic API for document extraction with human confirmation.

- Infrastructure as code on AWS (ECS Fargate or App Runner, RDS, S3, KMS, Secrets Manager, CloudWatch) or an agreed managed platform; CI with tests and security scans; staging and production environments; runbooks.

- You work against a mock CCH server built from our specification; production runs are performed by the firm. You will never hold production credentials or see client data.

- Collaboration: a full-stack engineer on the portal and staff console; an AI assistant that writes specifications and reviews every pull request before the owner sees it; a weekly 30-minute call with the owner.

- After the build: a retained maintenance agreement including on-call during the filing season.

REQUIREMENTS

- 5+ years building Python backends in production, 2+ years as the person responsible for a system's reliability.

- Deep Postgres: schema design, migrations, transactions, indexing, point-in-time recovery.

- Integrations with unreliable third-party APIs: retries, idempotency, partial failure, long-running jobs with polling.

- Security habits: least privilege, secrets management, no sensitive data in logs, dependency hygiene. You can explain how you would design a system where the people who build it never see the data it holds.

- Docker; one major cloud; infrastructure as code.

- Clear written English; you document decisions and write runbooks without being asked.

- At least four hours of daily overlap with Israel (UTC+2); availability December 2026 through June 2027 at 30-40 hours per week.

NICE TO HAVE

- Fintech, payments, accounting, insurance or health-data experience; SOC 2 or ISO 27001 exposure.

- LLM API experience (Anthropic/OpenAI SDKs, tool use, structured outputs) or MCP servers.

- Experience with XML-heavy enterprise APIs.

- Russian or Hebrew (the owner speaks both; not required).

ENGAGEMENT TERMS

- Independent contractor (B2B) via Deel, Payoneer or Upwork; NDA, IP assignment and the firm's confidentiality agreement signed before access to any repository.

- Phase 1: December 1, 2026 to April 30, 2027, 30-40 h/week; USD 3,500-6,000 per month (or USD 30-45/h) depending on seniority and hours.

- Phase 2: May 2027 onward, retained maintenance 10-20 h/week plus on-call in season, priced separately.

- Access: development and staging only; no production data, no production credentials; mock CCH server and synthetic data.

- Remote; Ukraine, Poland, Georgia, Armenia, Serbia, Kazakhstan and similar time zones preferred. Not available to contractors located in Russia.

PROCESS

1. Written application with three short answers: (a) one third-party API integration you built that had to survive locks, rate limits or inconsistent responses, and what you did about it; (b) how you keep secrets and personal data out of logs in a system you run; (c) your availability December 2026 to June 2027 and your overlap with UTC+2.

2. 30-minute call with the owner.

3. Paid trial task: 10-15 hours over one week, USD 500 paid regardless of outcome, on the mock server with synthetic data.

4. References, contract, onboarding. Target start: December 1, 2026.

Apply with a CV or LinkedIn profile, links to code or systems you are proud of, and the three answers. Applications without the answers are not reviewed.

About the role:
We are looking for an experienced and dynamic Data Engineer with a curious and creative mindset to join our client’s team. The ideal candidate will have a strong background in Python, SQL and large-scale data pipelines. 

As a Data Engineer you will design, build and operate the data platform that powers the company: pipelines that ingest and transform very large datasets from external data partners, data models that the whole company queries, and services that make that data available to internal products. 
 

Location: Ukraine is mandatory.

Responsibilities:
-Design and build batch data pipelines that ingest, validate and transform multi-billion-row datasets from external data providers and internal systems;
- Model complex real-world data: dimensional models, reference data, and temporal data whose attributes change over time (e.g. slowly changing dimensions), and evolve those models safely as upstream sources change their schemas and semantics;
- Develop and operate workloads on our lakehouse platform (Databricks / Spark / Delta) and our data warehouse (Redshift), including migrating existing pipelines from the warehouse to the lakehouse;
- Orchestrate pipelines with Airflow: scheduling, dependencies, retries, backfills and alerting;
- Prove correctness, not just completion: design parity checks and reconciliation queries when replacing an existing pipeline, run large historical backfills, and investigate data discrepancies down to the row level;
- Build and maintain Python services and REST APIs that serve data to internal products;
- Optimize for performance and cost: query tuning, table design, workload management and right-sizing compute;
- Own what you ship: monitor production pipelines, participate in incident triage and root-cause analysis, and harden systems so the same failure does not happen twice;
- Collaborate cross-functionally with product managers, data scientists and stakeholders across the company to deliver on product roadmap;
- Work within an Agile team that releases cutting-edge new features regularly;
- Take a high degree of ownership and freedom to experiment with new technologies to improve our software.

Requirements:
- Proficiency in Python and using it as the primary development language in recent years;
- Expert-level SQL: comfortable writing, reading and tuning complex analytical queries against very large tables, and debugging why two result sets disagree;
- Hands-on experience with a distributed data processing platform (Spark/Databricks strongly preferred; EMR, Snowflake or BigQuery also relevant) and with a columnar data warehouse (Redshift, Snowflake, BigQuery, ClickHouse, etc);
- Ability to design complex data models: normalized, dimensional and temporal (slowly changing dimensions, effective-dated records, point-in-time correctness);
- Experience with workflow orchestration tools (Airflow or similar): building DAGs, managing dependencies and running backfills;
- Experience integrating third-party data feeds: handling schema drift, late or missing deliveries, vendor data-quality defects and versioned reference data;
- Experience building REST services in Python (FastAPI, Flask, etc);
- Experience developing, maintaining, and debugging problems in large server-side code bases;
- Working knowledge of AWS (S3, IAM, ECS or similar compute) and Docker;
- Good knowledge of engineering best practices and testing (unit test, integration test, code review, CI/CD);
- The desire to take a high level of ownership of the things you work on;
- Ability to learn new things quickly, maintain a high bar for quality, and be pragmatic;
- Must be able to communicate with U.S based teams;
- Experience with Delta Lake / medallion lakehouse architectures is a plus;
- Experience migrating legacy pipelines between platforms with strict parity requirements is a plus;
- Experience with advertising, media or measurement industry data is a plus;
- Ability to communicate effectively with the U.S.-based teams and work 11:00 AM — 8:00 PM EEST (11:00 — 20:00).

Tech Stack:
- Almost everything we run is on AWS (S3, ECS, EMR, RDS and more)
- Python is our primary language; SQL is everywhere;
- Databricks (Spark, Delta Lake) is our lakehouse platform; - Redshift and Postgres are our warehouses and operational databases;
- Airflow orchestrates our pipelines;
- Docker for packaging; GitHub Actions and Jenkins for CI/CD;
- Grafana, Sentry and OpenSearch for observability;
- Datasets measured in billions of rows.
