A Software Engineer at Parachute Health plays a critical role in transforming how healthcare communication and medical ordering operate. The engineering team is tasked with replacing outdated, paper-and-fax-based workflows with a clean, intuitive, and highly secure digital platform. By streamlining the ordering process for Durable Medical Equipment (DME), medical supplies, and specialized home care services, engineers directly reduce patient wait times for life-saving equipment and improve overall care coordination. As a Software Engineer, you will work on complex, high-impact systems that handle sensitive patient data while ensuring high availability and seamless integrations with external electronic health record (EHR) systems. The platform's scale and the critical nature of its domain require a focus on robust system design, data integrity, and strict adherence to security and HIPAA compliance. You will not just write code; you will design architectures that solve real-world logistical and medical coordination challenges. This position offers the opportunity to tackle deep technical problems—such as real-time state tracking, complex search indexing, and multi-party workflow coordination—within a collaborative, mission-driven environment. Success in this role requires a balance of strong technical execution, a product-minded approach to problem-solving, and a deep empathy for the clinicians, suppliers, and patients who rely on the platform daily.

PracHub editorial advice for the preparation topics above.
Prioritize Test-Driven Development (TDD)
When completing coding challenges, write your test cases early. Demonstrating that you think about edge cases and test coverage before finalizing your implementation is a significant indicator of engineering maturity.
During pair programming, explain your thought process out loud
The interviewer is as interested in how you navigate obstacles and accept feedback as they are in the final working code.
Prepare for Written Prompts
Some technical rounds may present requirements via a written README rather than a verbal explanation. Practice reading technical specifications carefully under time constraints, and do not hesitate to ask clarifying questions about the written requirements.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.

Keep soft-deleted accounts from blocking re-registration
app_user holds user_id, tenant_id, email CITEXT, password_hash (NULL for SSO principals), email_verified_at, auth_version, status ('invited','active','suspended','deactivated'), created_at, updated_at, deleted_at. Two live accounts for one address inside a tenant must be impossible, but an address freed by a soft delete must be reusable, and the same tenant may delete and re-register it repeatedly. Write the uniqueness DDL for PostgreSQL 16, then the equivalent for MySQL 8 where partial indexes do not exist, and say what each permits once three deleted rows already hold that address.
Approach
- Start from what is actually unique: not (tenant_id, email), but (tenant_id, email) among live rows. PostgreSQL says that directly — CREATE UNIQUE INDEX app_user_live_email ON app_user (tenant_id, email) WHERE deleted_at IS NULL. A full constraint over the same two columns burns the address permanently the first time someone deletes an account.
- Keep case-insensitivity in the type or the index, never in the application: CITEXT as given, or UNIQUE (tenant_id, lower(email)) as an expression index where the extension is unavailable. A case-sensitive unique column is exactly how two accounts for one human appear.
- For MySQL 8 the predicate has to move inside the key: add a discriminator column that is a constant 0 while the row is live and is set to user_id on delete, with UNIQUE (tenant_id, email, deleted_marker). Live rows share the constant and still collide; deleted rows differ from each other and stop colliding.
- State the NULL variant and its dependency: leaving the marker NULL for deleted rows also works, because a unique index treats NULLs as distinct — true in MySQL, and true in PostgreSQL only under the default NULLS DISTINCT, which PostgreSQL 15 lets you reverse. Check the polarity against the three existing deleted rows: constant-on-live is what preserves the collision you want, and reversing it silently admits duplicate live accounts.
Follow-up
- A deleted account re-registers with the same address the next day. Do the old resource rows follow the new user_id, and how does the API keep the two principals apart?
- How do you honour an erasure request while resource_revision.actor_user_id still references this table?
Replace offset paging on the resource feed with keyset
resource holds resource_id, tenant_id, owner_user_id, title, body_ref, version, status ('draft','active','archived','deleted'), created_at, updated_at, deleted_at, with an index on (tenant_id, status, updated_at DESC, resource_id DESC). The listing endpoint returns active resources for one tenant, newest update first, 50 per page, today with LIMIT 50 OFFSET n. Tenants reach page 400 and rows are created while they read. Write the keyset query, define what the cursor carries and how it is encoded, and say which part of the index each predicate uses. Assume PostgreSQL 16.
Approach
- Name the two failures separately. OFFSET 20000 makes the server produce and discard 20,000 rows, so page cost grows with depth rather than with page size. Independently, any write that changes how many rows sort above the offset moves the window between two fetches, and the direction decides which anomaly you get: an insert lands at the head of updated_at DESC and pushes already-returned rows down past the boundary, so they are returned a second time; a delete above the offset, or a row whose updated_at is bumped above the cursor, pulls rows up and one is never returned at all. Nothing in the response reveals either.
- Write the seek: WHERE tenant_id = $1 AND status = 'active' AND (updated_at, resource_id) < ($2, $3) ORDER BY updated_at DESC, resource_id DESC LIMIT 50. The row-value comparison is one index range rather than a disjunction, and both columns are NOT NULL, which is what makes that comparison well defined.
- Map each predicate onto the index: tenant_id and status are equality on the leading columns, (updated_at, resource_id) is the range, and the ORDER BY matches the index order so no Sort node appears and the scan stops after 50 rows. The DESC in the definition only matters for mixed directions — a plain ascending btree on the same columns is read backwards for this query.
- Put both sort columns in the cursor and nothing the client can tamper with into another tenant: base64 of (updated_at, resource_id), validated server-side, with tenant_id taken from the principal.
Follow-up
- The client asks for 'jump to page 400'. What do you offer instead, and what does the honest version cost?
- Sort order becomes user-selectable across four columns. How many indexes is that, and which would you refuse to add?

Listing latency scales with page size, not with filters
The tenant listing endpoint reads resource filtered by tenant_id and status, ordered by updated_at DESC, and returns each row plus the owner's display name from app_user and the actor of that resource's latest resource_revision. p99 is 55 ms at 10 rows per page and 1.4 s at 200. Database telemetry shows 401 statements per request, each under 1 ms, and nothing in the slow-query log. Diagnose the cause and give the fix, stating the statement count per request and the p99 you expect afterwards.
Approach
- Read the counters before forming a theory. 401 statements for 200 rows is one driver query plus two per row, and sub-millisecond execution with an empty slow-query log rules out a bad plan. The time is round trips, which is why it is invisible in every per-query metric and scales with rows returned rather than with filter selectivity.
- Name the two per-row statements from their normalised text: a single-row app_user lookup by user_id, and a resource_revision lookup by resource_id ordered by version DESC LIMIT 1. Confirm by dropping those two response fields and watching the statement count fall to one. That locates the calls in the serialisation layer, not the repository.
- Check that the arithmetic accounts for the whole gap. Measure one round trip to the replica in isolation; 400 trips at roughly 3 ms of network plus 0.2 ms of execution is about 1.3 s on top of a 55 ms baseline, which matches. If the multiplication had fallen short, the N+1 would only be part of the story and you would keep looking.
- Batch both lookups. Collect owner_user_ids and resource_ids from the driver query, then issue WHERE tenant_id = $1 AND user_id = ANY($2) for the users, and PostgreSQL's SELECT DISTINCT ON (resource_id) ... WHERE resource_id = ANY($2) ORDER BY resource_id, version DESC for the latest revision, which the UNIQUE (resource_id, version) index serves directly. On an engine without DISTINCT ON, use a lateral join or a row_number window. Three statements per request at any page size.
Follow-up
- The page size is capped at 200 today. What breaks first if it is raised to 2,000, and is it still this bug?
- How do you stop the next N+1 from reaching production, given that no individual query is slow and the endpoint's tests pass?

How technical are the initial screening rounds?
The initial conversational screen with recruiting is focused on your background and alignment. However, technical evaluations begin early in the process—sometimes starting with a short interactive coding challenge or a take-home programming assessment to ensure core coding competency before moving to deeper rounds.
Parachute Health Software Engineer candidate reports ↗What is the expectation around testing during the coding rounds?
High. Writing automated tests for your logic is not just a nice-to-have; it is a core evaluation criterion. Structuring your code to be modular and testable, and writing assertions to verify your logic, will significantly strengthen your evaluation.
Parachute Health Software Engineer candidate reports ↗How should I handle the open-ended nature of the architecture interviews?
Expect the prompts to be brief and business-oriented. Your job is to actively ask clarifying questions to uncover technical constraints, data volume expectations, and user workflows. Treat the session as a collaborative whiteboard discussion with your future team.
Parachute Health Software Engineer candidate reports ↗Does Parachute Health require experience with their specific tech stack?
While familiarity with their specific technologies is helpful, they value strong engineering fundamentals, clean coding practices, and solid architectural thinking over syntax memorization. You are generally welcome to use your language of choice for coding challenges.
Parachute Health Software Engineer candidate reports ↗What topics does Parachute Health test in interviews?
Parachute Health interviews most often cover Communication, Behavioral Interviewing, Eligibility & Benefits (E&B), System Design, and Project Management. The exact emphasis depends on the specific role you apply for.
