As a Software Engineer at Remedy Robotics, you will build the software foundation for the world’s first fully automated endovascular robotic platform. This role sits at the intersection of cutting-edge robotics, real-time systems, and life-saving medical technology. Your work directly impacts patients by automating complex, highly delicate vascular procedures where minutes can mean the difference between recovery and permanent disability. The software you write controls micro-precision hardware, processes high-frequency sensor feedback, and implements autonomous path-planning algorithms to safely navigate catheters through complex blood vessels. Unlike traditional software roles, you will deal with physical-world constraints, real-time deterministic requirements, and the extreme safety standards of medical devices. You will collaborate closely with Catheter Engineers, Electrical Engineers, and clinical experts to turn complex physical maneuvers into reliable, repeatable software routines. This position is both intellectually challenging and deeply meaningful. It requires engineers who are not only exceptional at writing clean, robust code but are also excited about solving open-ended physical and algorithmic problems. If you thrive in a highly collaborative, interdisciplinary environment where your code has immediate, tangible consequences in the real world, this role is a perfect fit.

PracHub editorial advice for the preparation topics above.
Emphasize Determinism
Whenever you are asked to write code or design a system, explicitly state how you are managing memory and processing latency. Show that you know how to avoid non-deterministic behaviors that could compromise a real-time control system.
Ask About the Physical Constraints
During system design questions, ask clarifying questions about the physical hardware. Inquire about motor encoder resolution, communication bus latency, mechanical backlash, and sensor noise. This shows you think like a true robotics engineer.
Prioritize Simplicity and Safety
Avoid over-engineering. In a medical device context, the simplest, most verifiable solution is almost always superior to a highly complex, theoretical one. Always explain how your design handles failures and keeps the system in a safe state.
Demonstrate Cross-Functional Curiosity
Show excitement about learning from other disciplines. Mentioning how you have worked with mechanical or electrical teams in the past to debug complex system behaviors highlights your readiness for the collaborative environment at Remedy Robotics.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.

Write the update path that detects a concurrent edit
resource carries version INT NOT NULL DEFAULT 1. resource_revision holds revision_id, resource_id, version, actor_user_id, change_kind, patch JSONB, request_id, created_at with UNIQUE (resource_id, version). outbox_event holds aggregate_type, aggregate_id, aggregate_version, event_type, payload, status. A PUT carries the version the client read. Write the exact statements for the single transaction that applies the edit, records the revision and enqueues 'resource.updated', and give the handler's branch on zero affected rows. Then say what PostgreSQL 16 does under READ COMMITTED when two of these updates hit one row at once.
Approach
- One transaction, three writes, no network call inside it: UPDATE resource SET title = $3, version = version + 1, updated_at = now() WHERE resource_id = $1 AND tenant_id = $4 AND version = $2; then INSERT the resource_revision row at version $2 + 1; then INSERT the outbox_event row at the same aggregate_version. The event goes to a table rather than a broker because no transaction spans both.
- Branch on the affected-row count before doing anything else. Zero has three causes — stale version, wrong tenant, row gone — so re-read once and map to 409 carrying the current version, or 404 for an id outside the caller's tenant, which also stops the endpoint confirming that another tenant's id exists.
- State the engine behaviour instead of assuming it. Under READ COMMITTED the second UPDATE blocks on the row lock, and when the first commits PostgreSQL re-evaluates the WHERE clause against the newly committed row, so the version predicate now fails and the statement reports zero rows. Under REPEATABLE READ the identical collision raises SQLSTATE 40001 instead, so the handler must fold both shapes into one conflict response.
- Keep UNIQUE (resource_id, version) even though the predicate already serialises writers. It is what makes a lost update unwritable if any other path ever reaches the revision table, and it converts a logic bug into 23505 rather than into a silently missing history row.
Follow-up
- A client sends the version it read ten minutes ago and the resource has moved three versions. What is in your 409 so it can resolve the conflict without a full re-fetch?
- Two editors, two disjoint fields, no overlap. Does your answer still refuse the second write, and should 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?
