What is a remote open source developer?

A Remote Open Source Developer is a software engineer who contributes to open source projects while working from a location outside of a traditional office. These developers collaborate with distributed teams, often using online platforms like GitHub or GitLab to share code and track issues. Their work involves writing, testing, and documenting code, as well as reviewing contributions from others. Remote Open Source Developers may be volunteers or paid contributors, and they typically engage with a global community to improve and maintain open source software.

What are the key skills and qualifications needed to thrive as a remote open source developer, and why are they important?

To thrive as a Remote Open Source Developer, you need strong programming skills (often in languages like Python, JavaScript, or C++), familiarity with open source workflows, and a solid understanding of version control systems like Git. Experience with collaborative platforms such as GitHub or GitLab, and familiarity with continuous integration (CI) tools, are typically expected. Excellent written communication, self-motivation, and the ability to work independently and asynchronously help you stand out in distributed teams. These skills and qualities are essential to effectively contribute code, engage with global communities, and maintain productivity in a remote, open-source environment.

How does a remote open source developer typically collaborate with distributed teams and community contributors?

As a remote open source developer, collaboration often takes place through online platforms such as GitHub, GitLab, and community forums. You will regularly participate in code reviews, contribute to discussions on issue trackers, and join virtual meetings or chat channels with both core team members and external contributors. Strong written communication skills are essential, as most interactions are asynchronous and require clear documentation. You'll also need to be proactive in seeking feedback and providing updates, ensuring smooth progress on projects across different time zones.

Job description

About Our Client
Our client is a fast-growing, venture-backed software company building a modern operating system for communications service providers - a single platform managing billing, operations, and automation. The company is fully remote across the US and Canada and operates with a transparent salary philosophy, with compensation published internally under a structured evaluation framework.
About the Role
When a new customer joins the platform, their data has to come with them - out of legacy systems and into the client's product, accurately, completely, and on schedule. This role owns the technical execution of that work.
As a Data Migration Engineer on the client's migration delivery team, the role will own customer migrations end-to-end from the technical side: exploring legacy source systems, exporting data, transforming it into the platform's standard format, and driving it to a validated, production-ready state. The engineer works from business context and mapping rules defined by a customer-facing migration counterpart, and works daily in the company's internal migration tooling - improving it directly where possible and specifying larger needs for the platform engineering team to build.
This is a hands-on role for someone who enjoys turning messy, real-world data into something clean, repeatable, and trusted - and who is equally comfortable leading technical conversations directly with customers. The team is expanding significantly, so this hire will help shape how migrations are run going forward.
Key Responsibilities
  • Explore legacy source systems - databases, flat files, reports, APIs - to understand their structure, quality, and relationships in the context of the target data model.
  • Export source data across a range of access methods, including SQL, APIs, manual extracts, and database backups.
  • Transform exported data into the platform's standard format by authoring declarative, version-controlled mapping files that encode agreed business rules.
  • Execute migrations end-to-end on the internal migration platform: load, validate against target schemas, reconcile, and import to production.
  • Build and reuse mappings, templates, and validation rules so each migration is faster and more repeatable than the last.
  • Contribute engineering improvements to the migration tooling - validation rules, transforms, mapping updates - and raise larger needs to the platform engineering team.
  • Diagnose and resolve data discrepancies during dry runs, UAT, and post-cutover.
  • Document mapping specs, transformation logic, and data anomalies so migrations are auditable and repeatable.

What Success Looks Like
  • Source data lands in the platform accurately, completely, and on schedule - with discrepancies caught before go-live.
  • Transformation and validation work is reusable, so later migrations build on prior templates and rules.
  • Data issues are diagnosed and resolved quickly, keeping migrations on track.
  • Tooling gaps are either fixed directly or clearly specified for the platform engineering team.
  • Delivered data is trusted - accurate and well-documented enough to present to customers with confidence.
What the Right Person Brings
  • 3-5+ years in data engineering, data migration, ETL, or a similar hands-on data role.
  • Strong SQL and ETL fundamentals - treating extract → transform → load as a deliberate methodology: staging, repeatable and idempotent loads, full vs. incremental loads, and validation and reconciliation at every stage.
  • Hands-on data-manipulation fluency across SQL, Python, JSON, or similar - querying, profiling, reshaping data, and debugging unfamiliar source schemas.
  • Experience extracting data from varied sources: relational databases, APIs, flat files, and backups.
  • AWS experience - particularly Athena - and depth in SQL-based systems.
  • A background in high-volume, structured, or legacy data environments - for example banking, legal software, payroll, large CRMs, or enterprise SaaS with financial modules.
  • A proven ability to transform messy, poorly documented data into clean, structured output, with a solid grasp of data quality, validation, reconciliation, and cleansing.
  • Client-facing communication skills - comfortable leading technical conversations directly with customers.
  • Comfort in fast-paced, ambiguous environments with shifting source systems, and a bias toward reusability and automation over one-off scripts.
  • A Bachelor's degree in Computer Science, Information Systems, Data or Software Engineering, or a related field - or equivalent work experience.
Nice to Have
  • Familiarity with TypeScript/JavaScript (Node).
  • Familiarity with OSS/BSS, telecom, or billing/CRM data models (subscribers, services, billing accounts) - or a demonstrated ability to ramp quickly on unfamiliar domain models.
  • Comfort using AI-assisted tooling to accelerate data exploration, mapping, and validation.
  • Experience building or extending an internal data platform or migration tooling.
  • Exposure to cutover and go-live operations: delta loads, reconciliation, rollback.
  • Experience collaborating with a separate platform or product engineering team.
Compensation & Benefits
  • Our client offers competitive compensation aligned with experience and geography, under a transparent internal salary framework, along with:
  • A flexible 25-day vacation policy and flexible working hours.
  • Stock options.
  • Group insurance and telemedicine.
  • A life spending account and retirement savings plan.
  • 100% remote work, company-wide.
Equal Opportunity
Our client is an equal-opportunity employer. Accommodations are available on request throughout the hiring process. To learn more about this opportunity, please contact Accelerate HC.
