What This Role Does

What a dedicated API integration developer does inside your integration layer

This is not a script writer who hardcodes one-off connectors. A Miracuves dedicated API integration developer owns your connectivity - your API contracts, your retry policies, your observability on every external dependency. They make integrations boring in the best way. They work in your services and your monitoring, so failures surface as alerts rather than as a customer noticing that data stopped moving three weeks ago.

Every developer passes a live integration exercise with failure injection before matching. You choose engineers who have untangled production webhook storms - not coders who only read API docs once. This is the wrong hire if the systems you want connected have no usable interface at all, because that is a vendor negotiation before it is an engineering problem. In those cases we say so upfront and can recommend a full build engagement via our software development or clone solutions catalog instead. Compare sibling hire models and full-build options in the related section below.

Integrations fail silently

The dangerous failure is not the one that throws an error. It is the sync that quietly stops and is discovered a month later, by which point the two systems disagree.

What's Included

Every engagement includes this - no add-on tiers

01

Direct Repository Access

Added directly to your GitHub or GitLab. Work committed to your repository from day one - never a separate codebase.

02

Weekly Demo & Sprint Review

Every Friday, working software demonstrated live - not a written status update. You see exactly what shipped.

03

NDA + IP Assignment Day One

Bilateral NDA and IP assignment signed before any detail is discussed. All code belongs to you - confirmed in writing.

04

Async-First Communication

Daily written updates via Slack regardless of timezone, plus live sync during your guaranteed overlap window.

05

Release & Deployment Handled

CI/CD pipeline runs, build profiling, and release coordination - included, not billed separately.

06

2-Week Replacement Guarantee

If the match isn't right within the first 2 weeks, Miracuves replaces at no additional cost.

Honest Comparison

Miracuves vs Toptal, Turing, and Upwork - an honest comparison

Marketplaces optimise for transaction volume. Miracuves optimises for embedded delivery accountability - published rates, vetting you can verify, and a replacement guarantee if the match fails. Use this table when stakeholders ask why not Toptal, Turing, or Upwork - we answer plainly because the wrong engagement model wastes quarters. Procurement teams use it to compare IP ownership, overlap hours, and who remains accountable when delivery slips - not just hourly rate on a spreadsheet.

What They Own

What an integration developer actually owns

Integrations fail quietly. A sync that stops working on a Tuesday and is noticed the following month is worse than one that never worked, because by then the data has diverged.

Contracts
What each side promises
Agreed payloads and versioning, so a change at one end does not silently break the other. Most integration failures are a contract nobody wrote down.
In scope
Failure
What happens when it breaks
Retries, backoff and dead-letter handling, because the other system will be down at some point and losing the record is not acceptable.
In scope
Idempotency
Safe to run twice
Duplicate deliveries handled without double-charging or double-creating. Every real-world queue redelivers eventually.
In scope
Auth
Keeping credentials working
Token refresh, rotation and expiry handled properly, since expired credentials are the most common cause of a sync stopping.
In scope
Visibility
Knowing it is still running
Alerting when volume drops to zero, not just when an error is thrown. Silent success and silent failure look identical without it.
In scope
Mapping
Data that means the same thing
Reconciling fields that look equivalent and are not, which is where most integration bugs actually live.
In scope

Team Structures

Four ways to structure your integration team

Start with one integration specialist or scale into a connectivity pod for multi-partner platforms. Miracuves documents which practitioners join your squad, overlap hours, escalation path, and replacement SLA in the engagement letter - whether you embed individuals, a multi-role pod, or fractional leadership alongside delivery.

Onboarding

From signed NDA to first production commits

Most clients have a matched engineer in their repository within 48 hours of agreement. This is the standard onboarding path - not a best-case story used only in sales calls.

01

Day 0 - Brief & NDA

You share stack, timezone, sprint cadence, and access expectations. Miracuves signs bilateral NDA before technical details. Matching criteria documented in writing - role seniority, compliance needs, and overlap hours - not a vague 'send resumes' request. If the role requires clearance or niche certifications, Miracuves states timeline impact upfront.

02

Day 1-2 - Shortlist & Interview

You receive one to three profiles that already passed vetting and a paid trial exercise. You run your technical interview; Miracuves does not block direct engineer access. Profiles include verifiable project history and stack tags - not keyword-stuffed CVs. Rate and structure confirmed in writing before the engineer touches your repository.

03

Day 2-3 - Onboarding

Engineer added to your GitHub, Slack, Jira or Linear, and CI/CD. Branch strategy, review rules, and first sprint goal agreed in a 60-minute kickoff - not a week of vendor orientation. Miracuves engineers use your conventions: PR template, lint rules, and release branches from day one.

04

Week 1 - First Demo

Working commits and a Friday demo of shippable output. Async updates daily inside your overlap window. Miracuves stays accountable if ramp is slower than agreed - replacement SLA applies. You evaluate fit on real code review quality, not a take-home that never ships to your main branch.

05

Ongoing - Scale or Exit

Add QA, design, or backend capacity under the same engagement letter. Month-to-month terms with two weeks' notice - no annual lock-in unless you request rate stability. When staffing is no longer the right model, Miracuves can transition you to a full product build via our technology and vertical pages without changing NDA counterparty.

First 72 Hours

What happens after you say yes

01

NDA & brief locked

Stack, timezone, and matching criteria captured in writing before anyone touches your repo.

02

Vetted shortlist delivered

One to three profiles that already passed Miracuves vetting - you interview directly, no recruiter relay.

03

Repo access & kickoff

GitHub, Slack, and sprint tools connected; 60-minute kickoff sets week-one goals and review rules.

Full Catalog

Build with Miracuves - staffing or full product delivery

Not sure staffing is the right model? Miracuves also ships complete products from 90+ clone bases and custom builds - same company, same NDA, same IP ownership. Many clients start with a dedicated engineer, then expand into a squad or switch to a vertical clone deployment when scope clarifies. Every hire page links to published technology stacks, vertical clone deployments, and sibling engagement models so stakeholders compare staffing versus turnkey product delivery under one NDA counterparty.

Frequently Asked

Questions about hiring from Miracuves

How is a dedicated Miracuves integration developer different from buying an iPaaS connector pack?

Connector packs cover happy paths until a partner changes schemas, rate limits you, or duplicates webhook delivery. Miracuves developers own those edge cases - idempotency, partial failures, schema drift, OAuth token refresh, and observability across distributed transactions. They commit integration code to your repositories, embed in your release process, and pass vetting that includes live webhook debugging, not drag-and-drop tutorials alone.

Do you support REST, GraphQL, SOAP, and event-driven architectures?

Senior matches cover the integration styles you specify. Matching filters for GraphQL federation experience, legacy SOAP maintenance, Kafka or SQS event pipelines, and batch ETL where relevant. Miracuves does not label every backend developer an 'integration specialist' without verified partner-shipping history. Miracuves confirms structure, rate, timezone overlap, and IP assignment in your engagement letter before start - not verbal promises after you have paused the roadmap.

Can you work with enterprise middleware like MuleSoft, Boomi, or Celigo?

Yes - enterprise middleware experience is available in matched profiles for SAP, Salesforce, NetSuite, and custom ERP landscapes. Scope includes mapping maintenance, error stores, replay tooling, and partner onboarding runbooks. State your middleware stack during matching so vetting exercises reflect your production constraints.

How do you handle webhook reliability, retries, and duplicate delivery?

Idempotency keys, dead-letter queues, exponential backoff, and replay dashboards are core vetting scenarios - not afterthoughts added post-incident. Senior developers design integrations assuming partners will timeout, duplicate events, and ship breaking schema changes without warning. Miracuves confirms structure, rate, timezone overlap, and IP assignment in your engagement letter before start - not verbal promises after you have paused the roadmap.

Will developers document APIs and maintain OpenAPI specs for partners?

Yes. OpenAPI or AsyncAPI specs, partner integration guides, sandbox examples, and contract tests are standard deliverables - not optional documentation phases billed separately. Good integration work is maintainable by your internal team and external partners without tribal knowledge. Miracuves confirms structure, rate, timezone overlap, and IP assignment in your engagement letter before start - not verbal promises after you have paused the roadmap.

OAuth, SAML, and SSO flows are breaking in production. Can you help?

Auth integration including OAuth 2.0, SAML federation, token refresh, and scoped credential rotation is standard senior criteria. Vetting includes debugging broken auth flows under time pressure - a common real-world failure mode marketplace profiles often underestimate. Miracuves confirms structure, rate, timezone overlap, and IP assignment in your engagement letter before start - not verbal promises after you have paused the roadmap.

What engagement length makes sense for a partner onboarding burst vs ongoing integration ownership?

Partner onboarding bursts often start part-time at $1,499/mo and scale to full-time during parallel partner launches. Ongoing ownership of integration platforms typically stays full-time month-to-month. Miracuves confirms structure before start - no forced annual contract for a six-week connector project. Miracuves confirms structure, rate, timezone overlap, and IP assignment in your engagement letter before start - not verbal promises after you have paused the roadmap.

Who owns connectors, middleware configs, and integration IP?

Your organization retains all code and configuration under signed IP assignment. Integrations live in your repositories and middleware tenants - not a Miracuves-hosted black box. Handoff includes runbooks for partner escalation and on-call playbooks your team can operate. Miracuves confirms structure, rate, timezone overlap, and IP assignment in your engagement letter before start - not verbal promises after you have paused the roadmap.
